Arrhythmogenic right ventricular dysplasia masquerading as an abdominal episode

A 19-year-old woman presented with abdominal pain. Aside from epigastric tenderness, the patient's physical examination was unremarkable. She developed ventricular tachycardia with left bundle branch block morphology shortly after admission. Echocardiography revealed a thin, enlarged, and hypokinetic right ventricle. Electron beam computed tomography demonstrated hypodense areas in the right ventricular free wall suggestive of fatty infiltration, which suggested arrhythmogenic right ventricular dysplasia. The diagnosis was confirmed with the use of cardiac magnetic resonance imaging. The patient received an implantable cardioverter-defibrillator. This case illustrates a noncardiac presentation of a rare yet treatable cardiac condition.
