'''Arrhytmogenic Right Ventricular Cardiomyopathy''', (ARVC, or ARVD: Arrhythmogenic Right Ventricular Disease) is characterized by fatty replacement and fibrosis of the heart. Especially Most commonly the right ventricle apex and outflow tract are involved. However the left ventricle can be affected to.<cite>Corr</cite>
As a result of the fatty replacement and fibrosis, ventricular arrhythmias are common in this disease and can lead to palpitations, syncope and sudden death. At more advanced ages right ventricular pump failure can occur.
The diagnosis is based on major and minor criteria, as published by the European Society of Cardiology.<cite>McKenna1994</cite>
ARVC is a progressive disease. The '''incidence''' is estimated to be 1:3.000-1:10.000. Manifestations are usually seen during the teensin teenagers. Although the diagnosis is more often made in athletes, sports are not thought to have a causative relationship with the disease. ARVD can occur in families; more than 9 different chromosomal defects have been described, most often with autosomal dominant inheritance.
One unique form of ARVD, called Naxos disease (after the Greek island where it was first diagnosed), has an autosomal recessive pattern of inheritance.
