Chronic (or healed) myocarditis mimicking arrhythmogenic right ventricular dysplasia.

The aetiology of arrhythmogenic right ventricular dysplasia is still unknown, and there are few reports on familial coincidence in the literature. A case of a previously healthy man with an episode of acute myocarditis is described. After recovery from acute myocarditis, the patient was resuscitated from aborted sudden cardiac death 16 months later. Angiographic and electrophysiological evaluation suggested the pattern of arrhythmogenic right ventricular dysplasia. The case seems to suggest that arrhythmogenic right and/or left ventricular dysplasia could be mimicked by chronic (or healed) myocarditis.
