Left Ventricle Noncompaction Phenotype: Cause or Consequence?

Left ventricular noncompaction (LVNC) is commonly described as a congenital cardiomyopathy characterized by prominent myocardial trabeculae and deep intertrabecular recesses extending in the left ventricular chamber. Clinical presentation can differ considerably from asymptomatic individuals to those presenting with heart failure and other serious complications. Diagnosis is usually made by two-dimensional transthoracic echocardiography or cardiac magnetic resonance. Moreover, even if strain parameters are significantly reduced in patients with LVNC, they are not routinely investigated. Here, we report the case of a previously symptomless patient admitted to the hospital for pulmonary edema. Two-dimensional transthoracic echocardiography showed severe valvular heart disease and left ventricle pronounced trabeculation and remodeling, although speckle tracking echocardiography (STE) demonstrated only mild strain reduction. We, therefore, explore the possibility that STE may be useful to differentiate LVNC cardiomyopathy from LVNC phenotype due to severe remodeling.

Effectiveness of levosimendan and role of cardiac magnetic resonance in cardiogenic shock due to COVID-19 related lymphocytic myocarditis in the course of viral sepsis.

COVID-19 and sepsis pose great challenges to clinicians and growing evidence is demonstrating links between the two conditions. Both can be complicated by acute heart failure. The use of levosimendan in patients with ventricular dysfunction during COVID-19 infection and sepsis has very little evidence. A 46-year-old, hypertensive and obese patient was admitted for severe left ventricular failure and shock during sepsis following a COVID-19 infection. The patient was treated first with norepinephrine, which was partially effective, then with the addition of levosimendan as a continuous 24 hours infusion. Vital signs and echocardiographic systolic performance indices, such as FE, SVi, CI, dP/dT, TAPSE, and tricuspid S-wave velocity, as well as diastolic function, were recorded at access, 12 and 24 hours. After initiation of levosimendan, a rapid improvement in vital signs and systolic and diastolic performance indices was observed, not depending on changes in preload, afterload, and inflammatory status. Blood cultures were negative for the presence of bacteria, thus defining the picture of likely viral sepsis. Cardiac magnetic resonance was determinant, showing a picture of myocarditis sustained by immune processes rather than direct viral injury, which was confirmed by endomyocardial biopsy. In conclusion, this case highlights the efficacy of levosimendan in acute heart failure complicated by shock due to COVID-19-related myocarditis and concomitant sepsis and confirms cardiac magnetic resonance as the gold standard for the diagnosis of myocardial inflammatory disease. To the best of our knowledge, this is the first documented case of effective use of levosimendan in this context.

Accordion sign in COVID 19 related acute myocarditis, an old sign for a novel context? A cardiac magnetic resonance case series report study.

INTRODUCTION: The COVID-19 pandemic is related to a higher incidence of myocarditis; we present a case series of seven patients, admitted with COVID-19 related acute myocarditis, evaluated with cardiac magnetic resonance imaging, showing an altered profile of the free wall of the right ventricle, no longer present after six months follow-up. MATERIALS AND METHODS: Seven patients have been evaluated for COVID-19 related acute myocarditis, all patients have been evaluated with cardiac magnetic resonance imaging both in the acute setting and after six months follow-up. RESULTS: In the acute phase, myocarditis was confirmed in keeping with the current diagnostic criteria. In five out of seven cases, the presence of a crinkling profile of the free wall of the right ventricle was observed; at six months follow up, remission in four out of the five cases and a significant reduction in the remaining case, of the previously described findings, was observed. CONCLUSIONS: Crinkling appearance in the profile of the free wall of the right ventricle, detectable with cardiac magnetic resonance imaging, might represent a morphological feature present in the acute setting of COVID-19 related myocarditis; several underlying physiopathological mechanisms are conceivable. Further studies are needed to confirm this correlation, define the underlying mechanisms and the prognostic implication related to it. This is the first report in the literature that has considered such findings to the best of our knowledge.

When it's neighbor's fault, a complicated ascending aortic aneurysm mimicking pulmonary embolism: A case report.

Thoracic aortic aneurysms represent a potentially life-threatening disease with increasing prevalence, probably related to the increasing mean age of the global population; the complications of thoracic aortic aneurysms can show multiple modes of presentation in the acute phase based on various factors, including the involvement of the structures with which the aneurysm is in close anatomical relationship. With this case report we want to show how it is possible that a complicated ascending aortic aneurysm can mimic an acute pulmonary embolism/acute cor pulmonale in the acute phase; the earliest possible differential diagnosis between pulmonary embolism and acute aortic disease is of crucial importance due to the opposite implications that the treatment of these two diseases have. .

Tricuspid annular disjunction can be isolated and even arrhythmogenic. A cardiac magnetic resonance study.

Mitral annular disjunction is related to increased arrhythmogenic risk; in a certain percentage of cases, mitral annular disjunction is associated with tricuspid annular disjunction. While the prognostic implications of mitral annular disjunction have been well established, there is still little data to define this aspect regarding the tricuspid annular disjunction. We present a case of a patient admitted for life-threatening ventricular arrhythmias that occurred during endurance sporting activity, who was found to have isolated tricuspid annular disjunction, not associated with mitral annular disjunction. Based on several factors, including the morphology and axis of QRS of the ventricular arrhythmic activity, and its behavior, including the response to antiarrhythmic treatment, and in keeping with the finding of edema and late gadolinium enhancement at the basal segment of the right ventricle free wall on cardiac magnetic resonance imaging, a direct relation between tricuspid annular disjunction and ventricular arrhythmias was highly conceivable. Control after three months showed almost complete remission of the previously described and persistence of LGE at the level of the basal segment of the free wall of the right ventricle, so giving strength to the hypothesis of an event related to increased acute RV free wall stress, secondary to high-intensity physical activity, established on a framework of chronic wall stress, as represented by LGE, similarly to what happens for mitral valve prolapse. To the best of our knowledge, this is the first case of a legitimately conceivable direct relation between tricuspid annular disjunction and ventricular arrhythmias.

The spoils of war and the long-term spoiling of health conditions of entire nations.

The healthcare system of Ukraine was already suffering from several shortfalls before February 2022, but the war of aggression started by the Russian leadership is poised to inflict a further severe blow that will have long-lasting consequences for the health of all Ukrainians. In pre-war Ukraine, noncommunicable diseases (NCDs) contributed to 91% of deaths, especially cardiovascular diseases (67%). Ukrainians have a high prevalence of risk factors for NCDs ranking among the highest levels reported by the World Health Organization (WHO) in the European (EU) Region. Cardiovascular disease is one of the key health risks for the conflict-affected Ukrainian population due to significant limitations in access to health care and interruptions in the supply of medicines and resources. The excess mortality observed during the COVID-19 pandemic, due to a combination of viral illness and chronic disease states, is bound to increase exponentially from poorly treated NCDs. In this report, we discuss the impact of the war on the public health of Ukraine and potential interventions to provide remote health assistance to the Ukrainian population.

Reconsideration of the ECG in pericarditis; have we been led astray all these years?

Recently, new criteria for the diagnosis of pericarditis have been published. This paper has been thought to point out the limits in the new criteria specificity as well in the application of the new criteria for the diagnosis of pericarditis as recently demonstrated by studies based on cardiac magnetic resonance imaging. We report the case of A 18y old male with no significant past medical history who presented with complaints of chest pain typical for pericarditis, initially labeled as pericarditis; the patient was evaluated by electrocardiography, trans-thoracic echocardiography and cardiac magnetic resonance imaging; the condition, based on electrocardiogram and trans-thoracic echocardiography findings, was labeled as pericarditis in keeping with current diagnostic criteria. Cardiac magnetic resonance imaging demonstrated myocardial edema with no T2-defined pericardial inflammation on TIR/T2 imaging; late gadolinium enhancement imaging demonstrated multiple irregular, punctate, epicardial zones. The constellation of findings was consistent with acute myocarditis without pericardial involvement. In conclusion, limits in specificity of the newly published criteria for diagnosis of pericarditis, which add to the already demonstrated limits in sensitivity, subsist. Cardiac magnetic resonance imaging plays a unique role in the initial assessment of pericarditis; this is particularly important in the Covid-19 era in light of the increasing incidence of myocarditis and pericarditis; also, the case suggests that the combination of information between advanced echocardiography and cardiac magnetic resonance imaging may have an important diagnostic role in this setting. Additionally, we suggest that despite recent enthusiasm for colchicine, its role may be best defined in those with myocarditis, not pericarditis.

Where do we go from here? Beyond the MagnaSafe trial: A focus beyond a 'safety-first' notion. An MRI study in 500 consecutive patients.

BACKGROUND: In patients with conventional pacemakers or ICD's, MRI is infrequently performed due to safety concerns. Recent reports have allayed many of these concerns. However, the additive clinical value of scanning patients with cardiac implants has not been established. OBJECTIVE: Assessing the additive value of thoracic and non-thoracic MRI in patients with implantable cardiac devices. METHODS AND RESULTS: Prospective data were analyzed in 500 patients with implanted cardiac devices that underwent MRI over a 12 year period at a single institution (Allegheny General Hospital, Pittsburgh, PA). A set of three questions were answered following scan interpretation by both the MRI technologist and interpreting MRI physician(s): 1) Did the primary diagnosis change? 2) Did MRI provide additional information to the existing diagnosis? 3) Did patient management change? If 'Yes' was answered to any of the above questions, it was considered that the MRI scan was of value to patient diagnosis and/or guiding therapy. Scans encountered were neurological/neurosurgical 354 (70.8%), cardiac 98 (19.6%) and orthopedic 48 (9.6%) in nature. In 431 (86%) MRI added additional information to the primary diagnosis and in 277 (55.4%) MRI changed the primary diagnosis. In 304 (60.8%) cases management changed, 265 (53%) due to a change in diagnosis and in 39 (7.8%) due to providing additional information. No safety issues were encountered and no adverse effects of MRI scan were noted. CONCLUSIONS: MRI in patients with implanted cardiac devices was of additive value to diagnosis and management thereby informing risk-benefit considerations. CONDENSED ABSTRACT: 500 patients with implanted cardiac devices who underwent a MRI examination over a 12 year period were followed prospectively. Imaging primarily focus on three anatomical regions (neurological/neurosurgical, cardiac and orthopedic) providing added information to the primary diagnosis in 431 (86%) cases and changing the primary diagnosis in 277 (55.4%) cases. In 304 (60.8%) cases management changed with 265 (53%) being due to a change of diagnosis and in 39 (7.8%) due to providing additional information. No safety issues were encountered using a defined protocol. CONCLUSIONS: MR imaging retains its diagnostic yield in patients with implanted devices.

Reversibility of the endothelial dysfunction after CPAP therapy in OSAS patients.

BACKGROUND: The obstructive sleep apnoea syndrome (OSAS) is a common airways disease which often involves cardiovascular structures, causing vessel inflammation as well as hypoxia, induced by difficulties in the passage of air through the upper airways. Aim of our research is to evaluate the effects of Continuous Positive Airway Pressure (CPAP) on the syndrome itself and the patients cardiovascular risk profile, practically adopting Flow-Mediated Vasodilation (FMD) technique to evaluate endothelial function. METHODS AND RESULTS: We enrolled 63 patients (49 males and 14 female, mean age: 54 ± 10 years) subdivided into four groups: high cardiovascular risk factors, no CPAP therapy, CPAP therapy started less- and more than 3 months before. The patients underwent FMD of the brachial artery using a high resolution ultrasonograph connected to an image analysis system. The maximum recovery value was calculated as the ratio (maximum-baseline) of the change in diameter over the baseline value. Data obtained from this study demonstrate the significant reversibility of FMD in patients treated for more than 3 months with CPAP therapy (Group 4). CONCLUSIONS: Our study shows the importance of administering CPAP therapy for more than 3 months in patients suffering from OSAS to improve EF to a level equal to high cardiovascular risk subjects probably due to a recovery from the systemic hypoxia. Besides, our work points out the importance of FMD as a "clinical" tool able to point out any improvement or regression after therapies.
