Chronic right-sided myocarditis mimicking arrhythmogenic right ventricular dysplasia.
Arrhythmogenic right ventricular dysplasia (ARVD) is a cause of right ventricular 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 ARVD 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. The fact that right sided myocarditis can clinically mimic the genetic disease of classic arrhythmogenic right ventricular dysplasia has therapeutic implications for the patient and relatives.
