Hippo activation in arrhythmogenic cardiomyopathy.
A rrhythmogenic cardiomyopathy (AC) is an inherited heart muscle that affects ≈1 to 2 in 5000 individuals and accounts for 15% to 25% of cases of sudden cardiac death in patients <35 years. 1 The cardiomyopathy is characterized by risk for lethal ventricular arrhythmias, ventricular enlargement and dysfunction, and fibro-fatty replacement of cardio-myocytes. Curiously, the disease often disprop...
متن کاملNoninvasive diagnosis of electroanatomic abnormalities in arrhythmogenic right ventricular cardiomyopathy.
BACKGROUND The diagnostic reliability and pathophysiologic relevance of different noninvasive diagnostic criteria for arrhythmogenic right ventricular cardiomyopathy (ARVC) are undefined. We tested the association between noninvasive diagnostic criteria for ARVC and the presence of low-voltage areas (LVAs) detected at electroanatomic voltage mapping (EAM). METHODS AND RESULTS Noninvasive diag...
متن کاملDispersion of ventricular depolarization-repolarization: a noninvasive marker for risk stratification in arrhythmogenic right ventricular cardiomyopathy.
BACKGROUND We retrospectively investigated the value of clinical and ECG findings as well as QT-QRS dispersion in predicting the risk of sudden death in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC). METHODS AND RESULTS Duration and interlead variability of the QT interval and QRS complex were measured manually from standard ECGs in 20 sudden death victims with ARVC dia...
متن کاملArrhythmogenic cardiomyopathy
Arrhythmogenic cardiomyopathy is an inherited heart muscle disorder, predisposing to sudden cardiac death, particularly in young patients and athletes. Pathological features include loss of myocytes and fibrofatty replacement of right ventricular myocardium; biventricular involvement is often observed. It is a cell-to-cell junction cardiomyopathy, typically caused by genetically determined abno...
متن کاملNoninvasive and invasive evaluation of noncompaction cardiomyopathy.
Noncompaction cardiomyopathy is a recently described rare congenital cardiomyopathy; patients can be asymptomatic or develop diastolic and/or systolic left ventricular dysfunction with heart failure, systemic emboli or ventricular arrhythmias. Long-term prognosis is poor. Currently, diagnosis is based on findings on 2D echocardiography; in the current case report we demonstrate the use of MRI t...
