Abstract

A 35-year-old male with 7-year history of exertional dyspnea and abdominal distention hadfrequent premature ventricular contractions detected by Holter monitoring. Cardiovascularmagnetic resonance (CMR) imaging demonstrated a significantly dilated left ventricle (LV) withseverely reduced global systolic function. Coronary arterial stenosis was excluded with CT coronaryangiography. However, transmural late gadolinium enhancement was detected by CMRin the lateral wall of the LV. The patient received cardiac transplantation. The diagnosis of leftdominant arrhythmogenic right ventricular cardiomyopathy was made.
