Postmyocardial infarction ventricular septal defect is an increasingly rare mechanical complication of acute myocardial infarction. We present a case of acute myocardial infarction from right coronary artery occlusion that developed hypotension and systolic murmur 12 hours after successful percutaneous coronary intervention. Although preoperative imaging suggested a large ventricular septal def...

Background: Idiopathic right ventricular arrhythmias (IRVA) are responsive to medical and ablative treatment and have a benign prognosis. Arrhythmias caused by right ventricular dysplasia (ARVD) are refractory to treatment and may cause sudden death. It is difficult to distinguish between these two types of arrhythmia. Objective: To differentiate patients with IRVA and ARVD by a conventional el...

OBJECTIVE The main purpose of present study was to investigate the impact of percutaneous closure of atrial septal defect (ASD) on right ventricular (RV) systolic function assessed by tricuspid annular isovolumic myocardial acceleration (IVA) that is independent of preload and afterload changes. METHODS A prospective cohort study was designed involving twenty five patients with secundum type ...

BACKGROUND The p.Gln554X mutation in desmocollin-2 (DSC2) is prevalent in ≈10% of the Hutterite population. While the homozygous mutation causes severe biventricular arrhythmogenic right ventricular cardiomyopathy, the phenotypic features and prognosis of heterozygotes remain incompletely understood. METHODS AND RESULTS Eleven homozygotes (mean age 32±8 years, 45% female), 28 heterozygotes (m...

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is characterized by ventricular arrhythmias and fibrofatty replacement of the right ventricular (RV) myocardium. Although the RV is the predominant chamber involved, left ventricular (LV) involvement has also been documented. Electrophysiological correlations of histopathologic findings in nonischemic cardiomyopathy, and especially in ARVC,...

Our case report describes a very rare example of isolated right ventricular infarction in a 39-year-old patient with nondominant anomalous right coronary artery. We took advantage of both computed tomography and magnetic resonance imaging techniques to diagnose this case. The computed tomography scan characterized the anatomy and course of the right coronary artery and cardiac magnetic resonanc...
