Arrhythmogenic right ventricular dysplasia with massive involvement of the left ventricle.

Abstract

A 30-year-old male died suddenly after two years of clinically progressive episodes of recurrent ventricular tachycardia. In spite of recurrent episodes of palpitation, the patient had never shown signs or symptoms of heart failure before death. Post mortem examination revealed massive left ventricular involvement in addition to complete absence of myocardial tissue in the right ventricle, replaced by adipose tissue. This case illustrates that patients with arrhythmogenic right ventricular dysplasia may die of arrhythmia before failure of the left ventricle.
