What is arrhythmogenic right ventricular cardiomyopathy?

ARVC: Arvc is a cardiomyopathy that results in partial or total replacement of right ventricular muscle by fat or fibrous tissue. The principal problem is life-threatening heart rhythm disturbances which are the cause of death in these patients. Medications can suppress the arrhythmias but sometimes an aicd is needed. There is a genetic form of arvc. Cardiac MRI is useful for diagnosis.

A cardiomyopathy: Also called arrhythmogenic right ventricular dysplasia (arvd), it is a cardiomyopathy of the right ventricle. The muscle of the right ventricle is replaced by fat and fibrosis, which causes abnormal heart rhythms. It is a progressive disease. There is a genetic basis for arvd.
