Submitral left ventricular aneurysm (SMLVA) is a rare disease entity that exclusively occurs in the black population. We herewith report on a surgical case of SMLVA in a 68-year-old male who presented with ventricular tachycardia. He underwent surgical repair under standard hypothermic cardiopulmonary bypass. In the state of apical elevation, a vertical ventriculotomy was made directly over the aneurysm, which was located at the posterobasal aspect of the left ventricle. Radiofrequency ablation

His postoperative recovery was uneventful. There has been no dysfunction of the mitral valve or recurrence of the ventricular tachycardia at 2 years' follow-up.
