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.
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.
Genetics
This variant (609160) is associated with a mutation in the chromosome 10q22.3 region.[1]
