High prevalence of catecholamine-facilitated focal ventricular tachycardia in patients with arrhythmogenic right ventricular dysplasia/cardiomyopathy.
BACKGROUND Exercise-related ventricular tachycardia (VT) and high burden of premature ventricular contractions (PVCs) are common in arrhythmogenic right ventricular dysplasia/cardiomyopathy. We hypothesized that VT in arrhythmogenic right ventricular dysplasia/cardiomyopathy shows a high degree of association with the PVC at baseline. METHODS AND RESULTS The study population included 16 conse...
متن کاملDiagnostic value of isoproterenol testing in arrhythmogenic right ventricular cardiomyopathy.
BACKGROUND Although the Task Force Criteria for arrhythmogenic right ventricular cardiomyopathy (ARVC) have recently been updated, the diagnosis remains challenging in the early stages. The aim of this study was to evaluate the diagnostic value of β-adrenergic stimulation in ARVC. METHODS AND RESULTS We evaluated 412 consecutive patients (213 men, age 41.5±16 years) referred for premature ven...
متن کاملCharacterization of the Left-Sided Substrate in Arrhythmogenic Right Ventricular Cardiomyopathy.
BACKGROUND The correlates of left ventricular (LV) substrate in arrhythmogenic right ventricular (RV) cardiomyopathy are largely unknown. METHODS AND RESULTS Thirty-two patients with arrhythmogenic RV cardiomyopathy (47±14 years; 6 women) were included. RV and LV dysplasia were defined from multidetector computed tomography and cardiac magnetic resonance imaging. Arrhythmias were characterize...
متن کاملCatheter Ablation of Ventricular Tachycardia/Fibrillation in a Patient with Right Ventricular Amyloidosis with Initial Manifestations Mimicking Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy
Differentiating arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) from other cardiomyopathies is clinically important but challenging. Although the modified Task Force Criteria can facilitate diagnosis of ARVD/C according to clinical manifestations, histopathological examination plays a pivotal role in excluding other diseases that can mimic ARVD/C. Here, we report a patient wi...
متن کاملArrhythmogenic Right Ventricular Cardiomyopathy/Dysplasia
Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is characterized by progressive, fibrofatty replacement of the myocardium, ventricular arrhythmia, sudden death, and progressive heart failure. ARVC/D may be an important cause of syncope, ventricular arrhythmias, electrocardiogram (ECG) abnormalities and/or non-ischemic wall motion abnormalities. Some patients, however, do not ...
