Arrhythmogenic ventricular cardiomyopathy and sudden cardiac death: Left or right?

Abstract

Arrhythmogenic right ventricular cardiomyopathy is a leading cause of sudden cardiac death among athletes in Italy and the Mediterranean region. Although it often involves the right ventricle causing scarring, dilation, systolic impairment with aneurysm formation, it can also involve the left ventricle or present as isolated left ventricular cardiomyopathy. Cardiac magnetic resonance imaging is considered the gold standard in confirming the diagnosis. We summarize four cases of arrhythmogenic ventricular cardiomyopathy with different presentations observed over the past 2 years.
