Arrhythmogenic right ventricular dysplasia in the elderly.

Arrhythmogenic right ventricular dysplasia (ARVD) is a syndrome characterized by recurrent ventricular tachycardia. However, cases of ARVD have also presented as dilated cardiomyopathy later associated with ventricular arrhythmias. Histologically, this syndrome manifests as a fibrofatty replacement of the RV myocardium, predisposing the heart to ventricular arrhythmias. ARVD was once considered a disease of the young, but may be underrecognized in the older population. This report presents two cases of elderly men with newly symptomatic ARVD, believed to represent the oldest patients with ARVD described in the literature to date. The diagnosis of ARVD should be considered in individuals of all ages who present with a clinical syndrome consistent with ARVD and supportive evidence on ECG.
