Arrhythmogenic right ventricular dysplasia with left ventricular involvement: report of a case.

A case of arrhythmogenic right ventricular dysplasia with histological abnormality of the left ventricle is reported. Right ventriculography showed severe dilatation and hypokinesis, and left ventriculography also showed slightly diffuse hypokinesis. Histological findings of both ventricles revealed myocytolysis, severe fibrosis, and marked fatty infiltrations. It is therefore important to examine histologically both the left and right ventricles for such lesions.
