Abstract: Commotio cordis (Latin: "agitation of the heart") is a dysrhythmia provoked by praecordial trauma during the early part of cardiac repolarisation. Recorded rhythms include ventricular tachycardia/fibrillation, bradyarrhythmias, idioventricular rhythm, complete heart block and asystole. The quoted fatality rate is 65% even with prompt CPR and defibrillation, and exceeds 80% in the absence of such interventions. Above a certain threshold of trauma/impact, structural cardiac damage may also occur (contusio cordis).

Sudden cardiac arrest has been reported in patients with congenital anomalies of the coronary arteries. We present a rare case of sudden cardiac arrest caused by anomalous left main coronary artery originating high from the posterior aspect of left sinus of Valsalva with intramural retroaortic segment, associated with bicuspid aortic valve.
