چکیده
Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is characterized by progressive fatty and fibrous replacement. A female in her 70s, suddenly found in cardiopulmonary arrest. The heart weighed 452 g and yellow discoloration was observed. Histological examination revealed the replacement of the right ventricular myocardium by adipose tissue and fibrosis. The cause of death was fatal arrhythmia caused by ARVC/D. Tenascin C staining was useful in evaluating myocardial remodeling.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a disorder characterized by progressive replacement of myocardial cells by fibro-fatty tissue giving rise to ventricular tachyarrhythmias. In this case report, we describe a pediatric patient with sinoatrial arrests and second degree atrioventricular conduction block several years before ARVC became apparent. These findings suggest that ...

Reduced expressions of plakoglobin and connexin 43 have been reported in the myocardium of patients with arrhythmogenic right ventricular cardiomyopathy (ARVC). However, the relationships between these expression abnormalities and the clinical features of ARVC remain unknown.The expressions of plakoglobin and connexin 43 in myocardial biopsy specimens from 10 patients with confirmed ARVC, and 1...

Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is a genetically determined disease that progresses continuously from conception and throughout life. ARVC/D manifests predominantly in young adulthood. Early identification of the concealed cases in childhood is of utmost importance for the prevention of sudden cardiac death later in life. Magnetic resonance imaging (MRI) is ro...

BACKGROUND Cardiovascular magnetic resonance (CMR) is commonly used in patients with suspected arrhythmogenic right ventricular cardiomyopathy (ARVC) based on ECG, echocardiogram and Holter. However, various diseases may present with clinical characteristics resembling ARVC causing diagnostic dilemmas. The aim of this study was to explore the role of CMR in the differential diagnosis of patient...
متن کاملDifferential expression of B-type natriuretic peptide between left and right ventricles, with particular regard to sudden cardiac death
The aim of the present study was to investigate the differential expression of B‑type natriuretic peptide (BNP) between the left and right ventricle (RV) in sudden cardiac death (SCD). A total of 26 forensic autopsy cases of sudden death (survival time <30 min, postmortem interval <48 h or frozen within 6 h following death) in the present institute were examined. The cases consisted of acute is...
