What is Arrhythmogenic Right Ventricular Dysplasia (ARVD) best described as?

Explanation:
Arrhythmogenic Right Ventricular Dysplasia is a hereditary cardiomyopathy where the right ventricular myocardium is progressively replaced by fatty and fibrotic (scar) tissue. This fibrofatty replacement weakens the right ventricle, creates scar-based reentry circuits, and predisposes to ventricular arrhythmias and sudden death, especially in younger individuals. The hallmark is this specific tissue replacement in the right ventricle, rather than a failure of the left ventricle from ischemia, a global dilated cardiomyopathy, or a purely electrical tachycardia like AV nodal reentrant tachycardia.
