Chronic right-sided myocarditis mimicking arrhythmogenic right ventriculardysplasia

Arrhythmogenic right ventricular dysplasia (ARVD) is a cause of right ventr icular heart failure and has been implicated in some cases of sudden death in young adults, It is well known that a large majority of patients with AR VD have histological evidence suggestive of inflammation. Here we report a unique case of chronic myocarditis limited to the right ventricle and right side of the interventricular septum which presented clinically as ARVD. Th e fact that right sided myocarditis can clinically mimic the genetic diseas e of classic arrhythmogenic right ventricular dysplasia has therapeutic imp lications for the patient and relatives, Copyright (C) 2000 by W.B.
