This case highlights that left ventricular noncompaction with preserved ejection fraction can initially present as life-threatening ventricular tachycardia, requiring electrical cardioversion and strict adherence to antiarrhythmic therapy such as amiodarone.
The discovery of non-compaction cardiomyopathy of the left ventricle (NCVG), although rare, is not exceptional. This case involved a 36-year-old man admitted with palpitations, exertional dyspnea, hypersudation, and anxiety. The electrocardiogram revealed ventricular tachycardia. Transthoracic Doppler echocardiography and cardiac magnetic resonance imaging revealed hypertrabeculation of the left ventricle, with a ratio of noncompacted to compacted myocardium of 3.04. LVEF was 64%. The diagnosis of ventricular tachycardia revealing noncompaction of the left ventricle complicated by lateral ischemia was accepted. Anti-arrhythmic treatment with external electric shock enabled sinus rhythm to be achieved with a good reduction in tachycardia.
