Arrhythmogenic ventricular cardiomyopathy (AVC) is a heritable heart muscle disorder characterized by fibrofatty infiltration of the myocardium. Intramyocardial fat deposition is considered arrhythmogenic and predisposes patients to life-threatening arrhythmias and sudden cardiac death. The classic subtype of AVC is characterized by fibrofatty replacement of the right ventricular myocardium ( i.e. arrhythmogenic right ventricular cardiomyopathy). In advanced cases of arrhythmogenic right ventricular cardiomyopathy, the left ventricle may be involved as well. Predominantly left ventricular involvement by AVC is exceedingly rare and lack of specific diagnostic criteria as well as its potential cardiotoxic effect make its diagnosis challenging and of high importance.
