Background—Multiple morphologies, hemodynamic instability, or noninducibility may limit ventricular tachycardia (VT) ablation in patients with arrhythmogenic right ventricular dysplasia (ARVD). Substrate-based mapping and ablation may overcome these limitations. We report the results and success of substrate-based VT ablation in ARVD. Methods and Results—Twenty-two patients with ARVD were studi...
Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is characterized by progressive degeneration of the right ventricular myocardium, ventricular arrhythmias, fibrous-fatty replacement, and increased risk of sudden death. Mutations in 6 genes, including 4 encoding desmosomal proteins (Junctional plakoglobin (JUP), Desmoplakin (DSP), Plakophilin 2, and Desmoglein 2), have been ide...
Arrhythmogenic right ventricle dysplasia/cardiomyopathy (ARVD/C) is an inherited cardiomyopathy characterized by fibro fatty replacement of the right and less frequently left ventricle (1, 2). Ventricular arrhythmias requiring implantable cardioverter defibrillator (ICD) are common in patients with ARVD/C and electrical storm (≥3 life-threatening ventricular arrhythmia within 24-hour period) re...
Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is a life-threatening inherited cardiomyopathy with an estimated prevalence of 1 per 5000 individuals characterized by the replacement of the cardiac myocytes with fibrofatty tissue leading to ventricular arrhythmias, right ventricular failure, and sudden cardiac death. ARVD/C is commonly inherited in an autosomal dominant manne...
Introduction Ventricular arrhythmia (VA) is most commonly caused by ischemic heart disease. However, alternative etiologies of VA, including channelopathies, congenital heart disease, other cardiomyopathies such as hypertrophic cardiomyopathy, drugs, electrolyte imbalances, and infiltrative diseases must always be considered on the differential. Arrhythmogenic right ventricular dysplasia (ARVD)...
BACKGROUND Prior studies evaluating the efficacy of catheter ablation of ventricular tachycardia (VT) among patients with arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) have reported varied outcomes. More recently, studies have suggested that an epicardial ablation is necessary for improved outcomes after catheter ablation of VT. The overall objective of the present study wa...
OBJECTIVES The purpose of this study was to define the incidence and predictors of implantable cardioverter-defibrillator (ICD) therapy in patients with arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) after placement of an ICD for primary prevention. BACKGROUND Patients with a diagnosis of ARVD/C often receive an ICD for prevention of sudden cardiac death. METHODS Patient...
OBJECTIVES Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is characterized by fibrofatty replacement of cardiomyocytes. In around 50% of index patients, a genetic predisposition is demonstrated. The purpose of this study was to examine a plakophilin-2 (PKP2) splice site mutation, c.2489+4A>C, identified in 4 separately ascertained Dutch ARVD/C families. METHODS Genealogica...
Most sudden cardiac deaths in young athletes are caused by previously undetected inherited cardiac diseases. Here, we report a case of a young male athlete in whom a presumptive diagnosis of hypertrophic cardiomyopathy (HCM) was made following a near sudden cardiac death. Although his imaging studies initially suggested HCM, a detailed clinical and genetic evaluation of the patient and his asym...
