ABSTRACT

Background: The 2019 novel coronavirus disease (COVID-19) has been reported as pandemy and the number of patients continues to rise. Based on recent data, cardiac injury is a prominent feature of the disease, leading to increased morbidity and mortality. In the present study we aimed to evaluate myocardial dysfunction using transthoracic echocardiography (TTE) and tissue Doppler imaging (TDI) in hospitalized COVID-19 patients. Methods and Results: We recruited 30 patients (56.7% male, 55.80 +/- 14.949 years) who were hospitalized with the diagnosis COVID-19 infection. We analyzed left ventricular (LV) and right ventricular (RV) conventional and TDI parameters at the time of hospitalization and during the course of the disease. Patients without any cardiac disease and with preserved LV ejection fraction (EF) were included. TTE examination was performed and all the variables were recorded and analyzed retrospectively. We observed that both LV and RV conventional echocardiographic parameters were similar when the day of admission to the hospital was compared to the 5th day of the disease. Regarding TDI analysis, we demonstrated significant impairment in LV septal and lateral deformation (P < 0.001). In the correlation analysis no marked correlation was observed between impairment in LV deformation and inflammation biomarkers. Conclusion(s): Cardiac involvement is an important feature of the COVID-19 infection but the exact mechanism is still undefined. Echocardiography is an essential technique to describe myocardial injury and provide new concepts for the possible definitions of cardiac dysfunction.Copyright © 2023 The Author(s).

ABSTRACT

Objective. To assess the relationship between the severity of COVID-19 in patients without significant baseline cardiovascular pathology and various echocardiographic parameters of myocardial dysfunction. Material and methods. 46 patients with COVID-19 were included in our study: 33 patients of moderate severity and 13 - with severe disease. On days 1 and 9 upon admission, all patients underwent an echocardiographic study with standard assessment of the both ventricles function, as well as an assessment of their global longitudinal strain (GLS). Comparison of the studied parameters was carried out both between groups of patients and within each group in dynamics. Results. On day 1patients in the severe group had higher values of the systolic gradient on the tricuspid valve (22.0 [21.0;26.0] vs 30.0 [24.0;34.5] mm Hg, p = 0.02), systolic excursion of the plane of the tricuspid ring (2.3 [2.1;2.4] vs 2.0 [1.9;2.2] mm, p = 0.016), E/e' ratio (9.5 [7.7;8.9] vs 7.5 [6.8;9.3], p = 0.03). At day 9 among patients in the severe group, there was a decrease in end-diastolic (111.0 [100.0;120.0] vs 100.0 [89.0;105.0] ml, p = 0.03) and of end-systolic (35.5 [32.0;41, 2] vs 28.0 [25.0;31.8] ml, p < 0.01) volumes of the left ventricle. There was a decrease in GLS of the both ventricles compared to general accepted values. In dynamics, there was an increase in the GLS of the right ventricle in both groups, but it was more pronounced among severe group of patients (day 1 -18.5 [-15.2;-21.1] vs -20.2 [-15.8.1;-21.1] %, p = 0.03). The troponin levels were in the normal range. Conclusion. In COVID-19 patients without significant baseline cardiovascular pathology, there is a transient decrease in longitudinal strain of both ventricles, even in the absence of clinical and laboratory signs of acute myocardial injury.Copyright © Creative Cardiology 2021.

ABSTRACT

Submission content Introduction: An unusual case of a very young patient without previously known cardiac disease presenting with severe left ventricular failure, detected by a point of care echocardiogram. Main Body: A 34 year old previously well man was brought to hospital after seeing his general practitioner with one month of progressive shortness of breath on exertion. This began around the time the patient received his second covid-19 vaccination. He was sleeping in a chair as he was unable to lie flat. Abnormal observations led the GP to call an ambulance. In the emergency department, the patient required oxygen 5L/min to maintain SpO2 >94%, but he was not in respiratory distress at rest. Blood pressure was 92/53mmHg, mean 67mmHg. Point of care testing for COVID-19 was negative. He was alert, with warm peripheries. Lactate was 1.0mmol/L and he was producing more than 0.5ml/kg/hr of urine. There was no ankle swelling. ECG showed sinus tachycardia. He underwent CT pulmonary angiography which demonstrated no pulmonary embolus, but there was bilateral pulmonary edema. Troponin was 17ng/l, BNP was 2700pg/ml. Furosemide 40mg was given intravenously by the general medical team. Critical care outreach asked for an urgent intensivist review given the highly unusual diagnosis of pulmonary edema in a man of this age. An immediate FUSIC Heart scan identified a dilated left ventricle with end diastolic diameter 7cm and severe global systolic impairment. The right ventricle was not severely impaired, with TAPSE 18mm. There was no significant pericardial effusion. Multiple B lines and trace pulmonary effusions were identified at the lung bases. The patient was urgently discussed with the regional cardiac unit in case of further deterioration, basic images were shared via a cloud system. A potential diagnosis of vaccination-associated myocarditis was considered,1 but in view of the low troponin, the presentation was felt most likely to represent decompensated chronic dilated cardiomyopathy. The patient disclosed a family history of early cardiac death in males. Aggressive diuresis was commenced. The patient was admitted to a monitored bed given the potential risk of arrhythmia or further haemodynamic deterioration. Advice was given that in the event of worsening hypotension, fluids should not be administered but the cardiac centre should be contacted immediately. Formal echocardiography confirmed the POCUS findings, with ejection fraction <35%. He was initiated on ACE inhibitors and beta adrenergic blockade. His symptoms improved and he was able to return home and to work, and is currently undergoing further investigations to establish the etiology of his condition. Conclusion(s): Early echocardiography provided early evidence of a cardiac cause for the patient's presentation and highlighted the severity of the underlying pathology. This directed early aggressive diuresis and safety-netting by virtue of discussion with a tertiary cardiac centre whilst it was established whether this was an acute or decompensated chronic pathology. Ultrasound findings: PLAX, PSAX and A4Ch views demonstrating a severely dilated (7cm end diastolic diameter) left ventricle with global severe systolic impairment.

ABSTRACT

Objectives: Data about COVID-19 patients treated with veno-arterial-ECMO (VA-ECMO) is limited. Reported survival rates range from 27.9% to 77.8%, depending on VA-ECMO indication. A subgroup of patients suffers from circulatory failure due to a COVID-19 associated hyperinflammatory state (CovHI). In these patients, differentiation between inflammation and sepsis is difficult but important. In this retrospective case series, differential diagnoses of COVID-19 associated refractory circulatory failure and survival rates in different indications for VA-ECMO are investigated. Method(s): Retrospective analysis of 28 consecutive COVID-19 patients requiring VA-ECMO at the University Hospital Regensburg between March 2020 and May 2022. Specific treatment for COVID-19 was in accordance with respective guidelines. Mycotic infections were either invasive or met current definitions of COVID19-associated-pulmonary aspergillosis. Result(s): At VA-ECMO initiation, median age was 57.3 years (IQR: 51.4 - 61.8), SOFA score 16 (IQR: 13 - 17) and norepinephrine dosing 0.53mug/kg/min (IQR: 0.32 - 0.78). Virus-variants were: 61% wild-type, 14% Alpha, 18% Delta and 7% Omicron. Survival to hospital discharge was 39%. 17 patients were primarily supported with VA-ECMO only (survival 42%), 3 patients were switched from VV to VA-ECMO (survival 0%), and 8 patients were converted from VA to VAV or VV-ECMO (survival 50%). Indications for VA-ECMO support were pulmonary embolism (PE) (n=5, survival 80%), right heart failure due to secondary pulmonary hypertension (n=5, survival 20%), cardiac arrest (n=4, survival 25%), acute left heart failure (ALHF) (n=11, survival 36%) and refractory vasoplegia (n=3, survival 0%). Inflammatory markers at VA-ECMO initiation were higher in patients with ALHF or vasoplegia;in these patients a higher rate of invasive fungal infections (10/14, 71% vs. 4/14, 29%;p=0.023) compared to the other patients was found. Conclusion(s): Survival on VA-ECMO in COVID-19 depends on VA-ECMO indication, which should be considered in further studies and clinical decisions making. Circulatory failure due to vasoplegia should be considered very carefully as indication for VA-ECMO. A high rate of mycotic infections mandates an intense microbiological workup of these patients and must be considered as an important differential diagnosis to CovHI.

ABSTRACT

Objectives: Cases of fulminant myocarditis after mRNA COVID-19 vaccination have been reported. The most severe may need venoarterial extracorporeal membrane oxygenation (V-A ECMO) support. Here we report two cases successfully rescued with V-A ECMO. Method(s): We included all the cases supported with V-A ECMO for refractory cardiogenic shock due to myocarditis secondary to a mRNA SARS-COV2 vaccine in the high-volume adult ECMO Program in Vall Hebron University Hospital since January 2020. Result(s): We identified two cases (table). One of them was admitted for out-of-hospital cardiac arrest. In both, a peripheral V-A ECMO was implanted in the cath lab. An intra-aortic balloon pump was needed in one case for left ventricle unloading. Support could be successfully withdrawn in a mean of five days. No major bleeding or thrombosis complications occurred. Definite microscopic diagnosis could be reached in one case (Image, 3). Treatment was the same, using 1000mg of methylprednisolone/day for 3 days. A cardiac magnetic resonance 10 days after admission showed a significant improvement in systolic function and diffuse oedema and subepicardial contrast intake in different segments (Image, 1-2). Both patients were discharged fully recovered. Conclusion(s): V-A ECMO should be established in cases of COVID-19 vaccine-associated myocarditis with refractory cardiogenic shock during the acute phase. (Table Presented).

ABSTRACT

Introduction: Variants in PPP1R13L are associated with severe childhood-onset cardiomyopathy resulting in rapid progression to death or cardiac transplantation. PPP1R13L is proposed to encode a protein that limits the transcriptional activity of the NFkappaB pathway leading to elevated IL-1, IL-6, and TNF-alpha production in murine models. Optimal medical management for PPP1R13L-related cardiomyopathy is unknown. Here we report usage of a targeted anti-IL-1 immuno-modulatory therapy resulting in cardiac stabilization in a pediatric patient with congenital cardiomyopathy secondary to PPP1R13L variants. Case Report: A 4-year-old boy presented acutely with fever in the setting of persistent abdominal pain, vomiting, fatigue, and decreased appetite for two months following a mild COVID-19 related illness. Echocardiogram revealed severely depressed biventricular systolic function with an ejection fraction of 30%. Due to acute decompensated heart failure symptoms with hemodynamic instability, he was intubated and placed on continuous inotropic infusions with aggressive diuresis. Cardiac MRI demonstrated extensive subepicardial to near transmural fibrosis by late gadolinium enhancement in right and left ventricles. An implantable cardioverter-defibrillator (ICD) was placed due to frequent runs of polymorphic non-sustained ventricular tachycardia. Testing for viral pathogens was positive for rhino/enterovirus. Initial genetic testing was non-diagnostic (82-gene cardiomyopathy panel) but given the patient's significant presentation whole genome sequencing was pursued that showed two separate PPP1R13L variants in trans (c.2167A>C,p.T723P and c.2179_2183del,p. G727Hfs*25, NM_006663.4). Patient serum cytokine testing revealed elevations in IL-10 (4.7 pg/mL) and IL-1beta (20.9 pg/mL). Given the patient's tenuous circumstances and concern for continued progression of his cardiac disease, a trial of IL-1 inhibition via anakinra dosed at 3 mg/kg or 45 mg daily was initiated following hospital discharge. With approximately 6 months of therapy, the patient's cardiac function is stable with normalization of IL-10 and IL-1beta serum levels. Notably, the ventricular arrhythmia decreased after initiation of anakinra with no ICD shocks given. Therapy overall has been well tolerated without infectious concerns. Conclusion(s): In patients with PPP1R13L-related cardiomyopathy, immuno-modulatory therapies should be considered in an attempt to slow cardiac disease progression.Copyright © 2023 Elsevier Inc.

ABSTRACT

Introduction: The people worldwide have been affected by severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) infection since its appearance in December, 2019. Kawasaki disease-like hyperinflammatory shock associated with SARS-CoV-2 infection in previously healthy children has been reported in the literature, which is now referred to as a multisystem inflammatory syndrome in children (MIS-C). Some aspects of MIS-C are similar to those of Kawasaki disease, toxic shock syndrome, secondary hemophagocytic syndrome, and macrophage activation syndrome. Case Presentation: This study reported an 11-year-old boy with MIS-C presented with periorbital and peripheral edema, abdominal pain, elevated liver enzymes, severe right pleural effusion, moderate ascites, and severe failure of right and left ventricles. Conclusion(s): Due to the increasing number of reported cases of critically ill patients afflicted with MIS-C and its life-threatening complications, it was recommended that further studies should be carried out in order to provide screening tests for myocardial dysfunction. Adopting a multidisciplinary approach was found inevitable.Copyright © 2023, Author(s).

ABSTRACT

Objective To explore the clinical effect and safety of Suhexiang Pills () in the treatment of patients with tachycardia after severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. Methods A total of 138 patients with tachycardia after SARS-CoV-2 infection admitted to eight hospitals such as 971st Hospital of the PLA Navy, Changzhou Second People's Hospital, Xuzhou First People's Hospital, Henan Provincial People's Hospital, Henan Chest Hospital from February 2023 to March 2023 were randomly divided into control group and treatment group, with 87 patients in the treatment group and 51 in the control group. Patients in the control group were po administered with betaloc, once a day, and the initial dose was 23.75 mg, adjusted in time according to the patient's heart rate. Patients in the treatment group were po administered with Suhexiang Pills, 1 pill/time, twice daily. Patients in two groups were treated for 7 d. The clinical efficacy of the two groups was observed, and the heart rate and cardiac function indexes, RR interval, blood oxygen saturation and adverse reactions were compared between the two groups before and after treatment. Results After treatment, the total effective rate of the treatment group was 98.85%, and the total effective rate of the control group was 90.20%, and the difference between the two groups was statistically significant (P < 0.05). After treatment, heart rates were significantly decreased in both groups (P < 0.05), and the heart rates of the treatment group were significantly better than those of the control group (P < 0.05) on the 7th day of treatment. After treatment, the level of left ventricular ejection fraction (LVEF) in both groups was significantly higher than that before treatment (P < 0.05), and there was statistical difference between the treatment group and the control group (P < 0.05). The levels of left ventricular end diastolic dimension (LVEDD) and left ventricular end-systolic diameter (LVESD) in the treatment group significantly decreased than that before treatment (P < 0.05), and there was no statistical difference compared with the control group (P > 0.05). After treatment, the maximum RR interval in both groups reached the normal range on the third day, and the treatment group was significantly better than the control group (P < 0.05). Blood oxygen saturation of the treatment group was significantly increased on the 7th day of treatment compared with before treatment (P < 0.05), but there was no statistical significance between the two groups (P > 0.05). There was no significant difference in the total incidence of adverse events between the two groups (P > 0.05). Conclusion Suhexiang Pills decrease heart rates in patients with tachycardia after SARS-CoV-2 infection, which was equivalent to the effect of western medicine, and can protect heart, improve heart function to a certain extent.Copyright © 2023 Editorial Office of Chinese Traditional and Herbal Drugs.

ABSTRACT

Aim of the study. To study the experience of using focused transthoracic echocardiography in patients with COVID-19 in prone position (fEchoPr) in intensive care units (ICU). Materials and methods. The retrospective observational study included 53 patients (period from 15 April to 31 December 2020). Inclusion criteria: confirmed diagnosis of COVID-19, availability of fEchoPr data, outcome certainty (discharge/death). We analyzed electronic medical records. The fEchoPr was performed in patients in the prone position with a bolster under the left side of the chest and left arm raised ('swimmer's position'). We assessed the systolic function of the right ventricle (RV) (tricuspid annular plane systolic excursion (TAPSE)), RV size, RV/LV ratio, systolic function of the left ventricle (LV) (left ventricular outflow tract velocity time integral. (LVOT VTI)), and pulmonary hypertension (PH) (tricuspid regurgitation peak gradient (PGTR). Depending on the results, the patients were divided into 2 groups: informative (+fEchoPr) and non-informative (-fEchoPr) examinations. Results. There was no statistically significant difference in the groups (+fEcho n = 35 vs -fEcho n = 18) by age (65.6 +/- 15.3 vs 60.2 +/- 15.8, p > 0.05), by gender (male: 23 (65.7%) vs 14 (77.8%), p > 0.05), by body mass index (31.3 +/- 5.3 kg/m2 vs 29.5 +/- 5.4 kg/m2, p > 0.05), by mechanical ventilation support (24 (68.6%) vs 17 (94.4%), p = 0.074), by NEWS scale indicators (6.9 +/- 3.7 vs 8.5 +/- 3.5 points), by mortality (82.8% vs 94.4%, p > 0.05). Correlation analysis revealed a moderate inverse relationship between being on mechanical ventilation and the informative value of the study (Spearman's r = -0.30 at p = 0.033). In the +fEchoPr group, the correct measurement of TAPSE and RV/LV was carried out in 100%: a decrease in RV systolic function was recorded in 5 patients (14%), expansion of the RV in 13 patients (37%). Signs of PH were detected in 11 patients (31%), PGTR could not be measured in 10 patients (28%). LV systolic dysfunction was detected in 7 patients (20%). No pathology was detected in 16 patients (46%). One patient was diagnosed with infective endocarditis of native mitral valve, which was later confirmed by autopsy. Conclusion. In 66% of cases, fEchoPr examinations were informative, especially in terms of assessing the state of the right heart. fEchoPr examination is an affordable, valid and reproducible method to assess and monitor the state of the heart in ICU patients.Copyright © 2021 VIDAR Publishing House.

ABSTRACT

Introduction: Children requiring venoarterial (VA) extracorporeal membrane oxygenation for long durations may have increased risk of complications compared to venovenous (VV) ECMO. The purpose of this study was to evaluate the feasibility and safety of conversion from VA to VV ECMO. Method(s): This is a retrospective review of all children requiring VA ECMO who underwent conversion to VV ECMO at a single institution, from 2015- 2022. Indications for and methods of conversion were examined as well as adverse events including re-operation, ischemic complications, renal failure, and mortality. Descriptive statistics were calculated. Result(s): Of 422 pediatric patients on initial VA ECMO, only three children (0.7%) underwent conversion from VA to VV support, ages 10-19: for hypoxic respiratory failure due to COVID19, for cardiac dysfunction following orthotopic heart transplant, and for sepsis with associated left ventricular dysfunction. The indications for conversion were bleeding from cannulation site (n=2, 66%) and an anticipated prolonged ECMO run (n=1, 33%). For all three patients, the method of conversion was cutdown with femoral arterial repair followed by placement of additional jugular venous cannulas (n=2, 66%) or insertion of a singular jugular bicaval venous cannula with removal of the femoral cannulas (n=1, 33%). The median time on VA ECMO prior to conversion was 8 days (range 4-54 days). All 3 patients were managed with renal replacement therapy with 1 patient (33%) progressing to long term dialysis. There were no significant ischemic limb complications although one (33%) patient developed a femoral artery pseudoaneurysm that required re-operation. Two of the three patients (66%) were able to be decannulated at a median of 23.5 days (range 8-39 days) following conversion to VV ECMO and survived to discharge. The other patient was unable to be decannulated after successful conversion and care was withdrawn. Conclusion(s): Based on this small pilot study, conversion to VV ECMO from initial femoral VA ECMO cannulation is safe and feasible. Indications for conversion include coagulopathy and need for extended ECMO run after recovery of cardiac function.

ABSTRACT

Background/Aims Adult-onset Still's disease is a systemic inflammatory disease of unknown aetiology. Post-COVID-19 vaccine adult-onset Still's disease has been reported and was associated with only mild myocarditis. Here we report the first case of adult-onset Still's disease after mRNA COVID-19 vaccination presenting with severe myocarditis with acute heart failure and cardiogenic shock. Methods We described the case history of the patient. Results A 72-year-old Chinese woman developed gradual onset of fever, shortness of breath, sore throat, generalised arthralgia, malaise and poor appetite 15 days after receiving the first dose of BNT162b2 mRNA COVID-19 vaccine. Physical examination revealed fever, bilateral ankle oedema and elevated jugular venous pressure. Significant investigation results are shown in Table 1. Extensive viral panel tests (including enterovirus, influenza and cytomegalovirus) were all negative. Echocardiography showed severely reduced left ventricular ejection fraction of 20%. The acute heart failure was complicated by cardiogenic shock requiring intensive care unit admission. Myocarditis was later diagnosed. Although the heart condition subsequently improved, there were persistent fever and arthralgia, as well as the development of generalised maculopapular skin rash. In view of that, series of investigations were performed, which revealed persistent neutrophilic leucocytosis, hyper-ferritinaemia and liver function derangement, while autoimmune panel was grossly unremarkable and septic/viral workup was negative (Table 1). Contrast PET-CT scan showed no features of malignancy. Adult-onset Still's disease was diagnosed, and the patient was treated with oral prednisolone 40mg daily. The patient's condition responded to the treatment;the fever subsided and the leucocyte count and inflammatory markers were normalised, and she was subsequently discharged. Three months after discharge, the patient was clinically well with prednisolone tapered down to 5mg daily. Reassessment echocardiogram showed full recovery with LVEF 60%. Conclusion Severe myocarditis with acute heart failure and cardiogenic shock is a possible initial presentation of adult-onset Still's disease after mRNA COVID-19 vaccination. After exclusion of more common aetiologies, it is important to consider adult-onset Still's disease as one of the differential diagnoses in the presence of compatible features following COVID-19 vaccination, such that appropriate and timely workup and treatment can be offered.

ABSTRACT

Background: Among patients with COVID-19 infection, the risk of adverse cardiovascular outcome, particularly myocarditis and dysrhythmias remain elevated at least up to one year after infection. We present a case of atrial tachycardia and atrial Torsades de Pointes from COVID myocarditis, persisted 6 months after infection, which was successfully managed by ablation. Objective(s): A 25-year-old female presented with mild COVID-19 infection, Omicron variant, in May 2022. One month after, her Covid infection resolved;she presented with symptomatic atrial tachycardia, paroxysmal atrial fibrillation and flutter. ECG showed multiple blocked premature atrial contractions (PAC) (Figure 1A). Holter monitor showed PAC triggered atrial tachycardia degenerating to paroxysmal atrial fibrillation, atrial Torsades de Pointes. She has mild persistent troponin elevation. Echocardiography was normal. Cardiac MRI showed evidence of mild myocarditis with subepicardial late Gadolinium enhancement (LEG) along the lateral mid-apical left ventricular wall and edema. (Figure 1B). She was treated with Colchicine for 2 months. Repeat cardiac MRI 4 months after COVID infection showed resolution of edema and LGE. However, her symptomatic PAC and atrial tachycardia did not respond to betablocker and amiodarone. She underwent electrophysiology study. Activation mapping of PAC using CARTO revealed earliest activation at the right anterior atrial wall, with close proximity to tricuspid valve;unipolar signal showed QS pattern, bipolar signal showed 16 msec pre-PAC (Figure 1C and 1D). Mechanical pressure from ThermoCool SmartTouch ablation catheter (Biosense Webster Inc.) at this site suppressed the PAC. Radiofrequency ablation resulted with an initial acceleration and then disappearance of the PAC. We did not isolate pulmonary veins or ablate cavotricuspid isthmus. Post ablation, PAC and atrial fibrillation were not inducible on Isoproterenol. Method(s): N/A Results: Covid myocarditis can result in dysrhythmia that lingers long after Covid myocarditis has resolved. Covid myocarditis can be caused by direct viral invasion of myocytes or more commonly is inflammatory related to cytokine release and edema. Our case demonstrates that dysrhythmias can persist despite resolution of myocarditis. Catheter ablation can successfully to treat these arrhythmias. Conclusion(s): This case highlights the importance of recognizing cardiac dysrhythmia as possible the long-term cardiac complications of COVID-19, requiring specific treatment such as catheter ablation.

ABSTRACT

Case Presentation: Term male infant born to SARS-CoV-2 positive mother with infant testing negative. ECG for perinatal bradycardia revealed ventricular pre-excitation. Echocardiogram showed asymmetric LV hypertrophy with prominent trabeculations, subaortic narrowing with no pressure gradient, and normal biventricular systolic function. Rapid increase in RV pressure estimates and NT-proBNP in first week if life concerning for diastolic dysfunction. Anti-arrhythmic therapy initiated for SVT with subsequent resolution. Later, developed progressive LV dilation and systolic dysfunction. Myocardium showed regions resembling non-compaction and others concerning for infiltrative process. Cardiac MRI showed no obvious tumors, but rhabdomyomas could not be ruled out given similar appearance to myocardium. Due to worsening heart failure, everolimus therapy initiated to target potential rhabdomyomas while awaiting genetic testing for tuberous sclerosis. Subaortic narrowing and LV hypertrophy improved within days, and LV appearance became more consistent with non-compaction. Genetic testing revealed a TSC2 gene variant consistent with tuberous sclerosis. Systolic function improved, and patient discharged on afterload reduction. Echocardiogram 6 months post-discharge shows continued LV dilation and mild systolic dysfunction. Discussion(s): Although outflow obstruction and arrhythmias are common with cardiac rhabdomyomas and can cause dysfunction, our patient developed progressive dysfunction in the absence of outflow tract gradient or prolonged arrhythmia. As rhabdomyomas subsided, it became clearer that he had an underlying cardiomyopathy. We suspect that rhabdomyomas in the setting of abnormal myocardium led to abnormalities in myocardial contractility and compliance causing combined systolic and diastolic dysfunction. After complete resolution of rhabdomyomas, cardiac function has improved. However, he continues to have ventricular dilation and mild dysfunction attributable to cardiomyopathy. It is unlikely that mother's SARS-CoV-2 infection played a role as infant tested negative and clinical picture was not consistent with myocarditis.

ABSTRACT

COVID-19 is a highly transmissible disease with severe course especially in patients with nephrogenic hypertensive disease and chronic kidney disease due to a higher incidence of all-type infections than in the general population. The aim of the study is to describe a clinical case of SARS-CoV-2 infection complicated by nephrogenic pulmonary edema and COVID-associated pneumonitis, alveolitis. Description of the case. Patient K.S., born in 1975, was hospitalized 24 hours after symptom onset at emergency hospital due to complaints of increased blood pressure up to 180-200/110-120 mm Hg, temperature up to 38.7degreeC, dry cough, feeling of heaviness in the chest, change in urine color. PCR smear for SARS-CoV-2 was positive. Computed tomography revealed a pattern of bilateral COVID-associated pneumonitis, alveolitis, with 75% involvement. The electrocardiogram revealed signs of left ventricular myocardial hypertrophy. Ultrasound examination showed numerous cysts in the kidneys. Urinalysis at admission: leukocytes - 499, erythrocytes - 386. Glomerular filtration rate (CKD-EPI: 29 ml/min/1.73 m2) and corresponds to stage IV of chronic kidney disease. Coagulogram: fibrinogen: 32.3 (1.6-4.0) g/l, D-dimer: 663 (0-250). Despite the treatment, the patient's condition worsened, the phenomena of cardiopulmonary and renal insufficiency increased, which led to a fatal outcome. During a virological study of sectional material: SARS-CoV-2 coronavirus RNA was found in the lung and kidneys. Signs of bilateral COVID-associated pneumonitis, alveolitis with diffuse cellular infiltrates in combination with changes in the alveolar apparatus, signs of pulmonary edema were revealed. Heart-related signs - swelling of the interstitium, fragmented muscle fibers, some of them hypertrophied, a wave-like deformation of cardiomyocytes, blurring of the transverse striation. Arteries with thickened sclerosed walls. In the kidneys - diffuse damage to the proximal tubules of the nephron with areas of cortical and proximal necronephrosis, areas of fibrinoid swelling. Conclusion. The cause of death of a 45-year-old patient was a severe course of bilateral COVID-associated pneumonitis, alveolitis, which contributed to the development of renal medullary hypoxia and type 1 cardiorenal syndrome, which led to early nephrogenic pulmonary edema.Copyright © 2023 Saint Petersburg Pasteur Institute.

ABSTRACT

Aim. To investigate the relationship between echocardiographic parameters and laboratory immune inflammation signs in patients after coronavirus disease 2019 (COVID-19) pneumonia depending on the left ventricular (LV) involvement according to speckle tracking echocardiography (STE). Material and methods. The study included 216 patients (men, 51,1%, mean age, 50,1+/-11,1 years). The examination was carried out in patients 3 months after COVID-19 pneumonia. Patients were divided in 3 groups: group I (n=41) - diffuse decrease (>=4 segments the same LV level) of longitudinal strain (LS) according to STE;group II (n=67) - patients with regional decrease (LS reduction >=3 segments corresponding to systems of the anterior, circumflex or right coronary arteries);group III - patients without visual left ventricle involvement (n=108). Results. There were no significant differences in LV ejection fraction - 68,9+/-4,1% in group I, 68,5+/-4,4% in group II and 68,6+/-4,3 in group III (p=0,934). A decrease in the global longitudinal left ventricle strain was detected significantly more often in groups I and II compared with group III (-17,8+/-2,0, -18,5+/-2,0 and -20,8+/-1,8%, respectively;p<0,001). At the same time, LS depression of LV basal level (-14,9+/-1,5, -16,8+/-1,2% and -19,1+/-1,7%;p<0,001), as well as a decrease in LS of LV inferior-posterior segments in group with diffuse involvement was detected significantly more often than in groups II and III. In addition, we revealed a significant difference in interleukin-6 concentration - 3,1 [2,5;4,0], 3,1 [2,4;3,8] and 2,5 [3,8;1,7] pg/ml, (p=0,033), C-reactive protein - 4,0 [2,2;7,9], 5,7 [3,2;7,9] and 2,4 [1,1;4,7] mg/l, (p<0,001), tumor necrosis factor-alpha - 5,9+/-1,9, 6,2+/-1,9 and 5,2+/-2,0 pg/ml, (p=0,004) and ferritin - 130,7 [56,5;220,0], 92,2 [26,0;129,4] and 51,0 [23,2;158,9] microg/l, respectively (p=0,025). Conclusion. A relationship was found between diffuse and regional left ventricular involvement according to STE and signs of immune inflammation in patients 3 months after COVID-19 pneumonia.Copyright © 2023 Vserossiiskoe Obshchestvo Kardiologov.

ABSTRACT

Case Report: It is well documented that Coronavirus Disease 19 (COVID-19) patients who suffer cardiac injury have a higher mortality rate, however the exact mechanism of cardiac injury and potential complications are still unknown. Takotsubo Cardiomyopathy (TCM), which was first described in 1990 in Japan, is characterized by a transient systolic and diastolic left ventricular dysfunction with a range of wall motion abnormalities predominantly affecting women often following an emotional or physical trigger. Though TCM is seen less commonly as a cardiac complication of COVID-19, with increasing rates of cardiovascular events due to COVID-19, TCM should be taken into consideration as a potential diagnosis for a COVID-19 positive patient. Case Description: The case of a 75-year old female with a history significant for hypertension, type 2 diabetes mellitus, hyperlipidemia, and gastroesophageal reflux disease presented to the Emergency Department after a ground level fall and subsequent left hip pain. Upon primary survey, EKG showed persistent sinus tachycardia in the 130-150s, with intermittent borderline dynamic changes and a troponin that was mildly elevated at 0.10, and an initial false negative COVID-19 test. Preoperative echocardiogram showed normal left ventricle size, no regional wall abnormalities, and a left ventricular ejection fraction (LVEF) of 60-65%. In post-operative care, EKG illustrated dynamic changes in the form of ST elevation in the lateral precordial leads, as well as an increase in the cardiac troponins, from 0.07 to 3.51. A subsequent echocardiogram illustrated a drop in her ejection fraction from 60-65% to 30-35%, with evidence of left ventricular systolic dysfunction that was not noted on previous echocardiograms. Following the Mayo clinic diagnostic criteria, this patient met the diagnostic criteria for TCM, as evident by new electrocardiograph findings, non-obstructive cardiac catherization findings, echocardiogram findings illustrating transient left ventricular systolic dysfunction, modest elevations in cardiac troponins as well as the patient being a post-menopausal female. Subsequent echocardiogram on 2 week follow up showed a rebound in her ejection fraction to 50-55%. Discussion(s): Possible outcomes of TCM include cardiogenic shock, respiratory failure, and death. It is imperative that clinicians consider TCM as a possible diagnosis when treating COVID-19 patients that may be exhibiting cardiac complications. Frequent ECG monitoring and a vigilant differential should include TCM in patients presenting with COVID-19.

ABSTRACT

Case Presentation: A 19 year old male presented with sudden onset chest pain radiating to back. He was a smoker and denied using cocaine since his last hospitalization for cocaine-induced myocardial infarction 2 years ago. UDS was negative. EKG showed normal sinus rhythm with no ST-T wave changes. Initial troponin was 0.850. Potassium levels were low at 2.9 mmol/L but other labs were normal. Chest CT angiography ruled out aortic dissection. He was started on heparin drip. Stat Echocardiogram showed LVEF of 55-60% with no wall motion abnormalities. Repeat potassium levels normalized after replacement, however, his troponins were trending up from 3.9 and 11.5. He continued to complain of severe chest pain, so underwent cardiac catheterization which showed normal coronary arteries and LVEF 55-60%. Heparin drip was discontinued and NSAIDs and colchicine were started. Cardiac MRI (see Figure) was done that showed patchy mid-wall and epicardial delayed gadolinium enhancement involving the basal inferolateral wall, with mild hyperintense signal on the triple IR sequence, suggestive of myocarditis. On further probing, he reported receiving a second dose of Moderna COVID vaccine 3 days prior to presentation. Discussion(s): In December 2019, a novel RNA virus causing COVID-19 infection was reported, which quickly reached a pandemic level. COVID-19 vaccines were granted emergency use authorization by FDA. With millions of people receiving COVID-19 vaccinations worldwide, rare adverse effects are now being reported. The benefits of vaccination undoubtedly outweigh any minor side effects. However major adverse effects like this are potentially fatal. This case report warrants further investigation into the association of myocarditis with COVID-19 vaccinations and further recommendations regarding vaccination in younger adults.

ABSTRACT

Purpose of study Since mid-April 2020 in Europe and North America, clusters of pediatric cases with a newly described severe systemic inflammatory response with shock have appeared. Patients had persistent fevers >38.5 C, hypotension, features of myocardial dysfunction, coagulopathy, gastrointestinal symptoms, rash, and elevated inflammatory markers without other causes of infection. The World Health Organization, Centers for Disease Control, and Royal College of Paediatrics associated these symptoms with SARS-CoV-2 as multisystem inflammatory syndrome in children (MIS-C). Cardiac manifestations include coronary artery aneurysms, left ventricular systolic dysfunction evidenced by elevation of troponin-T (TnT) and pro-B-type naturietic peptide (proBNP), and electrocardiogram (ECG) abnormalities. We report the clinical course of three children with MIS-C while focusing on the unique atrioventricular (AV) conduction abnormalities. Case #1:19-year-old previously healthy Hispanic male presented with abdominal pain, fever, and non-bloody diarrhea for three days. He was febrile and hypotensive (80/47 mmHg) requiring fluid resuscitation. Symptoms, lab findings, and a positive COVID-19 antibody test were consistent with MIS-C. Methylprednisolone, intravenous immunoglobulin (IVIG), and enoxaparin were started. He required epinephrine for shock and high flow nasal cannula for respiratory distress. Initial echocardiogram demonstrated a left ventricular ejection fraction (LVEF) of 40% with normal appearing coronaries. Troponin and proBNP were 0.41 ng/mL and proBNP 15,301 pg/mL respectively. ECG showed an incomplete right bundle branch block. He eventually became bradycardic to the 30s-50s and cardiac tracing revealed a complete AV block (figure 1a). Isoproterenol, a B1 receptor agonist, supported the severe bradycardia until the patient progressed to a type 2 second degree AV block (figure 1b). A second dose of IVIG was administered improving the rhythm to a type 1 second degree AV block. An IL-6 inhibitor, tocilizumab was given as the rhythm would not improve, and the patient soon converted to a first-degree AV block. Cardiac magnetic resonance imaging showed septal predominant left ventricular hypertrophy and subepicardial enhancement along the basal inferior/anteroseptal walls typical for myocarditis. Case #2: 9-year-old previously healthy Hispanic male presented after three days of daily fevers, headaches, myalgias, diffuse abdominal pain, and ageusia. He was febrile, tachycardic, and hypotensive (68/39 mmHg). Hypotension of 50s/20s mmHg required 3 normal saline boluses of 20 ml/kg and initiation of an epinephrine drip. Severe hypoxia required endotracheal intubation. After the MIS-C diagnosis was made, he was treated with IVIG, mehtylprednisolone, enoxaparin, aspirin, and ceftriaxone. Due to elevated inflammatory markers by day 4 and patient's illness severity, a 7-day course of anakinra was initiated. Initial echocardiogram showed mild tricuspid and mitral regurgitation with a LVEF of 35-40%. Despite anti-inflammatory therapy, troponin and proBNP were 0.33 ng/mL and BNP of 25,335 pg/mL. A second echocardiogram confirmed poor function so milrinone was started. Only, after two doses of anakinra, LVEF soon normalized. Despite that, he progressively became bradycardic to the 50's. QTc was prolonged to 545 ms and worsened to a max of 592 ms. The aforementioned therapies were continued, and the bradycardia and QTc improved to 405 ms. Patient #3: 9-year-old African American male presented with four days of right sided abdominal pain, constipation, and non-bilious non-bloody emesis. He had a negative COVID test and unremarkable ultrasound of the appendix days prior. His history, elevated inflammatory markers, and positive COVID- 19 antibody were indicative of MIS-C. He was started on the appropriate medication regimen. Initial ECG showed sinus rhythm with normal intervals and echocardiogram was unremarkable. Repeat imaging by day three showed a decreased LVEF of 50%. ECG had since changed to a right bundle branch block. Anakinra as started and steroid dosing was increased. By day 5, he became bradycardic to the 50s and progressed to a junctional cardiac rhythm. Cardiac function normalized by day 7, and anakinra was subsequently stopped. Thereafter, heart rates ranged from 38-48 bpm requiring transfer to the pediatric cardiac intensive care unit for better monitoring and potential isoproterenol infusion. He remained well perfused, with continued medical management, heart rates improved. Methods used Retrospective Chart Review. Summary of results Non-specific T-wave, ST segment changes, and premature atrial or ventricular beats are the most often noted ECG anomalies. All patients initially had normal ECGs but developed bradycardia followed by either PR prolongation or QTc elongation. Two had mild LVEF dysfunction prior to developing third degree heart block and/or a junctional escape rhythm;one had moderate LVEF dysfunction that normalized before developing a prolonged QTc. Inflammatory and cardiac markers along with coagulation factors were the highest early in disease course, peak BNP occurred at approximately hospital day 3-4, and patient's typically had their lowest LVEF at day 5-6. Initial ECGs were benign with PR intervals below 200 milliseconds (ms). Collectively the length of time from initial symptom presentation till when ECG abnormalities began tended to be at day 8-9. Patients similarly developed increased QTc intervals later in the hospitalization. When comparing with the CRP and BNP trends, it appeared that the ECG changes (including PR and QTc elongation) occurred after the initial hyperinflammatory response. Conclusions Although the mechanism for COVID-19 induced heart block continues to be studied, it is suspected to be secondary to inflammation and edema of the conduction tissue. Insufficiency of the coronary arterial supply to the AV node and rest of the conduction system also seems to play a role. Although our patients had normal ECG findings, two developed bundle branch blocks prior to more complex rhythms near the peak of inflammatory marker values. Based on the premise that MIS-C is a hyperinflammatory response likely affecting conduction tissue, our group was treated with different regimens of IVIG, steroids, anakinra, and/or tocilizumab. Anakinra, being an IL-1 inhibitor, has been reported to dampen inflammation in viral myocarditis and tocilizumab has improved LVEF in rheumatoid arthritis patients. Based on our small case series, patient's with MISC can have AV nodal conduction abnormalities. The usual cocktail of IVIG and steroids helps;however, when there are more serious cases of cardiac inflammation, adjuvant immunosuppresants like anakinra and toculizumab can be beneficial.

ABSTRACT

Introduction: Use of hematopoietic cell transplantation (HCT) in patients with trisomy 21 (+21) is infrequent given concerns about increased toxicity with cytotoxic chemotherapy.1 Due to increasing evidence of benefit from post-HCT cyclophosphamide (PTCy) for graft-vs.-host disease (GVHD) prophylaxis and lack of prior descriptions in patients with +21,2-4 we report on 2 patients with +21 and acute lymphoblastic leukemia (ALL) who underwent HCT with PTCy. Method(s): Retrospective data were collected from 2 patients with ALL and +21 who underwent allogeneic HCT with PTCybased GVHD prophylaxis from 2019 to 2021. Data collected included age, disease risk, HCT-CI, GVHD incidence, and survival. Result(s): Patient 1 is a 22-year-old male and patient 2 a 25-year-old female. Both had Ph-negative, B-cell ALL. Patient 1 had ETV6/RUNX1 rearrangement, del 12p, gain of X, and he had recurrence of measurable residual disease (MRD) after initial MRD-negative CR with two lines of therapy pre-HCT. Patient 2 had normal cytogenetics and relapsed disease with 4 prior lines of therapy. Both achieved MRD-negativity pre-HCT. Both received fludarabine and melphalan conditioning, and patient 1 also received thiotepa 2.5 mg/kg. PTCy was given on days +3 and 4 at 50 mg/kg with sirolimus and tacrolimus for GVHD prophylaxis. Patient 1 had a haploidentical donor and received one dose of rabbit ATG (1 mg/kg) on day +5. Patient 2 had a matched unrelated donor. There was no significant delay in engraftment of ANC (day 16-19) or platelets (day 15-16). Patient 2 developed acute GVHD at day 30 (stage I skin, stage II GI) that resolved with steroids which were tapered off by day 96 without recurrence. Sirolimus stopped at day 79 (pt 1) and 103 (pt 2) and tacrolimus was stopped at day 274 (pt 1) and 469 (pt 2). Patient 1 developed a sirolimus-induced pericardial effusion at day 84 which did not recur after sirolimus discontinuation. Patient 2 developed moyamoya 8 months post-HCT during tacrolimus taper without other GVHD symptoms. Response to steroids was noted, so tacrolimus was restarted for residual neurological deficit. Neither patient developed chronic GVHD or left ventricular ejection fraction decline, and neither patient had disease relapse at follow-up of 30 and 16 months respectively. Patient 2 developed COVID pneumonia 16 months post-HCT and died while in CR. Patient 1 remains alive, in CR, and off immunosuppression nearly 3 years post HCT. Conclusion(s): Allogeneic HCT with PTCy at standard doses did not appear prohibitively toxic in patients with +21 when administered after reduced-intensity conditioning. In this case series, GVHD rates seemed consistent with larger series in patients without +21. Moyamoya development is associated with autoimmunity in patients with +21 and hence may have been GVHD-related5. Trisomy 21 should not be a barrier to patients otherwise eligible for HCT, even with PTCy prophylaxis.Copyright © 2023 American Society for Transplantation and Cellular Therapy
