Systemic disease presenting as cardiac tamponade: a case report.

Background: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by multisystem inflammation and is a common cause of pericarditis and pericardial effusion, but significant pericardial effusion and cardiac tamponade are rare and even rarer as the first manifestation. Case summary: We report the case of a young male who presented with fever, recurrent pericarditis, and polyserositis with pericardial and bilateral pleural effusion. On examination, he was haemodynamically unstable and the pericardial effusion had considerable dimensions and an urgent pericardiocentesis was performed. Antinuclear antibody with a speckled pattern was positive, complement C4 levels were low, and the remaining autoimmunity and infectious study was unremarkable. Considering the European League Against Rheumatism/American College of Rheumatology classification criteria for SLE, a score of 11 points was obtained, confirming the diagnosis of SLE. Discussion: This case report illustrates a rare form of presentation of SLE, in which the first manifestation was pericarditis with polyserositis and cardiac tamponade.

Nonbacterial thrombotic endocarditis of mitral valve associated with a lymphoproliferative malignancy: case report and literature review.

BACKGROUND: Non-bacterial thrombotic endocarditis (NBTE) is a rare condition marked by sterile vegetations on cardiac valves, often linked to rheumatologic diseases, autoimmune disorders, and advanced solid malignancies. An early diagnosis and treatment of the associated clinical condition are mandatory, although they do not usually eliminate valvular vegetations, making anticoagulation essential to prevent embolic events. Despite variability, the prognosis of NBTE is usually unfavorable due to recurrent embolic events and the severity of the primary condition, typically advanced cancer. CASE PRESENTATION: We present a case of a 57 years-old male who presented to the emergency department with a 5-day history of painful bilateral digital edema and color change episodes (from pallor to cyanosis). Physical examination revealed erythrocyanosis in the distal extremities, prompting consideration of secondary Raynaud syndrome. Despite medical therapy, progressive digital ischemia led to multiple finger amputations. During etiological investigation, anticoagulation tests and autoimmune analysis yielded negative results. A transesophageal echocardiogram was performed, revealing an irregular hyperechogenic mass on the anterior leaflet of the mitral valve without valve dysfunction, and a thoracic computed tomography scan with contrast showed an enlarged right paratracheal lymph node. Histopathological analysis from a transthoracic needle biopsy of the paratracheal lymph node revealed diffuse large B-cell lymphoma. The patient underwent aggressive R-CHOP chemotherapy, achieving a favorable complete response. CONCLUSION: This is a particular case involving the occurrence of NBTE and Raynaud phenomenon as the initial paraneoplastic manifestations in a previously healthy young man. Reports of NBTE associated with lymphoproliferative conditions are quite rare, with fewer than ten cases described in the literature. To our knowledge, this is the first case of NBTE specifically associated with diffuse large B-cell lymphoma.

Heart rate score in remote monitoring: An additional tool for predicting outcomes in heart failure with reduced ejection fraction.

BACKGROUND: Heart rate score (HRS) ≥ 70% has been associated with arrhythmic events and mortality but these studies were not specific for heart failure (HF) patients. We hypothesized that HRS ≥ 70% obtained from remote monitoring (RM) is associated with HF hospitalizations and arrhythmic events in HF with reduced ejection fraction (HFrEF). METHODS: HRS was calculated from RM in patients with HFrEF and ICD or CRT-D. Two groups were defined: HRS ≥ 70% (G1, n = 55) and HRS < 70% (G2, n = 48) RESULTS: A total of 103 patients were included (64.4 ± 13.04 years, 69.9% male, mean left ventricular ejection fraction (LVEF) 33.62 ± 11.97% and FUP 61.7 ± 38.87 months). The device was CRT-D in 59.2% and ICD in 40.8% and the majority (90.3%) had the device implanted in primary prevention. G1 patients were more frequently male (p = .017) and had more coronary disease (p = .035). HRS ≥70% was an independent predictor for unplanned HF hospitalizations (OR: 1.905 (95% CI: 1.328-3.649), p < .001)). The indication for device implantation (primary vs. secondary prevention), type of device, NYHA class, age, gender and LVEF were not independent predictors of the outcome. VF (4.9 ± 20.0 G1 vs. 1.1 ± 5.47 G2, p = .046) and VT episodes were more prevalent in G1 (3.1 ± 8.93 G1 vs. 0.3 ± 1.59 G2, p = .026), as well as appropriate device shocks (4.3 ± 12.06 G1 vs. 0.3 ± 1.49 G2, p = .023). There was no difference in inappropriate shocks or mortality outcomes between groups. CONCLUSION: HRS ≥70% obtained from RM was an independent predictor of HF hospitalizations and was associated with arrhythmic events with VT and VF episodes and appropriate device shocks in HFrEF patients.

Heart surgery waiting list management in an ultra-peripheral region: impact of a risk-stratified queuing method.

BACKGROUND: The management of heart surgery waiting list is essential, particularly in ultraperipheral regions. We aimed to characterise a cohort of patients awaiting surgery in such a region, and to assess the occurrence of adverse events and causative factors. METHODS: A retrospective, multicentre analysis from 2016 to 2020. Patients were divided into "Urgent group" vs "Priority group" based on surgical priority. A composite outcome of death or hospital admission was determined. RESULTS: We included 329 patients, 18.2% in the Urgent group. Baseline characteristics were similar, except for a higher prevalence of smoking habits in the Urgent group (56.7% vs 38.7%, p = 0.016), as well as the CCS class (p = 0.014) and EuroScore surgical risk (p < 0.001). Disease acuity indicated highest priority for coronary artery bypass grafting patients. Myocardial revascularization and aortic valvular replacement were the main procedures. Overall, 15.2% of patients received treatment within recommended waiting time, with 50.8% being Urgent patients. Urgent patients had higher risk for composite outcome (HR 3.92, 95% CI 1.26-12.22; p = 0.019), with fewer events reported (5% vs 17.8%, p = 0.051). Chronic kidney disease and previous open-heart surgery were independent predictors of this outcome. Chronic kidney disease remained as independent predictor at 1-year follow-up, while surgical priority did not affect outcomes. CONCLUSIONS: Despite similar occurrences of adverse events on the waiting list, longer waiting times for patients in the Urgent group increase their risk of adverse events. The priority level had no impact on outcomes. Chronic kidney disease and open-heart surgery were independent predictors for events, highlighting their significance in the triage process.

Acute Chest Pain and Electrical Alternans.

A young man presented with acute stabbing chest pain. A 12-lead electrocardiogram revealed electrical alternans with phasic variation of the QRS amplitude in all leads. Lung auscultation revealed absent left hemithorax breath sounds. Chest radiography confirmed a left-sided tension pneumothorax. Tension pneumothorax is a very rare cause for electrical alternans. (Level of Difficulty: Intermediate.).

Primary cardiac lymphoma: The unusual suspect and the importance of a multimodality approach.

Primary cardiac lymphomas are rare tumors with heterogeneous presentation, often difficult to diagnose, requiring a high level of clinical suspicion. An attempted diagnosis is fundamental for effective treatment. We report a very rare case of a primary cardiac lymphoma in a middle-age female patient that presented with atrial flutter, atrioventricular conduction disorder, and a secondary autoimmune hemolytic anemia with cold agglutinin syndrome. The investigation was challenging and a definite diagnosis was achieved by histopathological study and corroborated by regression after chemotherapy. Learning objectives: Primary cardiac tumors are rare, often difficult to diagnose, and a multimodality imaging approach is essential for diagnosis. Although complete atrioventricular (AV) block is often an indication for permanent pacemaker, reversible causes should be considered. AV blocks caused by infiltration of lymphoma can resolve after effective treatment and so it may be reasonable to delay pacemaker implantation until after treatment. A multidisciplinary approach is fundamental in complex cases.

Double coronary anomaly: A case report.

We describe an extremely rare case of a 37-year-old female patient who presented with exertional angina and was diagnosed with a unique coronary anomaly with an anomalous right coronary artery with origin in the left anterior descending artery and a fistula between this anomalous coronary artery and the pulmonary artery. Learning objectives: Most patients with coronary anomalies are asymptomatic but some may have angina caused by a coronary steal phenomenon, myocardial infarction, or even sudden death depending on the circuit and characteristics of the anomaly.The combination of multiple coronary anomalies is extremely rare.Despite being a rare diagnosis, coronary anomalies should always be considered as a cause of myocardial ischemia, especially in young patients with low probability for coronary obstructive disease.
