Abstract

A 37-year-old man without a significant medical history had an out-of-hospital sudden cardiac arrest. A bystander started cardiopulmonary resuscitation, and emergency medical services arrived promptly, confirmed ventricular fibrillation, and restored sinus rhythm. An emergent coronary arteriogram was normal. Transthoracic echocardiography revealed a severely reduced left ventricular ejection fraction and suggested left ventricular noncompaction. The patient’s heart failure with reduced ejection fraction was treated with carvedilol, lisinopril, and spironolactone, and after he was weaned from the ventilator he received an implantable cardioverter-defibrillator. The patient’s identical twin was treated in the same fashion for a sudden cardiac arrest. Although many experts think that left ventricular noncompaction cardiomyopathy is a distinct nosological entity, others think that it is simply a dilated cardiomyopathy with unusually prominent left ventricular trabeculae.
