Arrhythmogenic Right Ventricular Dysplasia

Arrhythmogenic right ventricular dysplasia (ARVD) is a rare form of cardiomyopathy.

Arrhythmogenic right ventricular dysplasia (ARVD) is a rare form of cardiomyopathy. It occurs when the heart muscle tissue in the right ventricle dies and is replaced by fat or scar tissue. As a result, the heart cannot pump properly. Patients with ARVD often have arrhythmias, which can increase the risk of sudden cardiac death. ARVD usually occurs in teens and young adults. It has also been linked to sudden cardiac death in young athletes.

What are the causes?

Doctors do not know what causes ARVD. It often runs in families, but it can occur in people with no family history of the condition. ARVD may also be caused by congenital conditions (those that are present at birth) and viral or inflammatory myocarditis.

What are the symptoms?

Symptoms of ARVD include palpitations and fainting after physical activity, ventricular arrhythmias, dizziness, and lightheadedness. Heart failure may also be a symptom of ARVD.

How is it diagnosed?

How is it treated?

There is no known cure for ARVD. Instead, treatment is focused on relieving the symptoms. You will likely be given antiarrhythmic medicines. If there is a risk for sudden death, your doctor may recommend an implantable cardioverter defibrillator. If you have ARVD, you will need to ask your doctor about exercising or participating in sports.
