Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a disease of the heart muscle. In this disease, fatty fibrous tissue replaces normal heart muscle. This interrupts normal electrical signals in the heart and may cause irregular and potentially life-threatening heart rhythms. The heart also becomes weaker over time leading to heart failure. It was previously called arrhythmogenic right ventricular dysplasia (ARVD). ARVC typically begins in a small part of the right ventricle. Over time, the disease slowly affects more of the right ventricle. Sometimes the left ventricle is affected, too. This can lead to abnormal heart rhythms, and sometimes sudden death. Over time, the heart can’t pump as much blood forward as it normally would. Blood backs up in the circulatory system causing fluid to build up in the soft tissues or the lungs. This can lead to many symptoms, such as swelling (edema) and shortness of breath. This is called heart failure. ARVC is a fairly rare genetic disease. S
