Overview
Arrhythmogenic right ventricular dysplasia is a type of nonischemic cardiomyopathy that involves primarily the right ventricle. It is characterized by hypokinetic areas involving the free wall of the right ventricle, with fibrofatty replacement of the right ventricular myocardium, with associated arrhythmias originating in the right ventricle. This variant of ARVD is somewhat unusual as some family members were found to have involvement of the left ventricle and left bundle branch block.
Pathophysiology
The pathogenesis of ARVD involves apoptosis with fatty and fibro-fatty infiltration of the right ventricular free wall leading to heart failure and ventricular arrhythmias. This variant of ARVD is somewhat unusual as some family members were found to have involvement of the left ventricle and left bundle branch block.
