Left ventricular involvement in arrhythmogenic right ventricular cardiomyopathy demonstrated by multidetector-row computed tomography.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a condition in which the right ventricle is partially or totally replaced by the adipose tissue. Pathological abnormalities affect the left ventricle as well as the right ventricle, particularly the epimyocardium. Multidetector-row computed tomography, which allowed excellent visualization of not only the coronary arteries but also the myocardium with submillimeter spatial resolution and high signal-to-noise ratio, would be more suitable for the assessment of the extent of adipose tissue involvement in the right and left ventricular myocardium. We present a patient who was diagnosed as having ARVC with left ventricular involvement and underwent cardioverter defibrillator implantation.
