Risk Stratification in Arrhythmic Right Ventricular Cardiomyopathy Without Implantable Cardioverter-Defibrillators

Abstract Objectives The primary objective of this study is risk stratification of patients with arrhythmic right ventricular cardiomyopathy (ARVC). Background There is a need to identify those who need an automatic implantable cardioverter-defibrillator (ICD) to prevent sudden death. Methods This is an analysis of 88 patients with ARVC from 3 centers and who were not treated with an ICD. Results Risk factors for subsequent arrhythmic deaths were pre-enrollment sustained or nonsustained ventricular tachycardia and decreased left ventricular function. Conclusions These factors serve as proposed guidelines for implantation of an ICD in patients with ARVC to prevent sudden death.
