Surgical Management of Submitral Aneurysm

Submitral left ventricular aneurysm is a rare entity. It is mostly in Africans; the most prevalent etiology is congenital. It is also seen rarely in Caucasians and Asians due to varied etiologies. The diagnosis may be achieved by transthoracic echocardiography, transesophageal echocardiography, or even left ventricular angiography. We present a case where the former was misleading and the latter could not be performed due to cardiac failure, yet diagnosis was achieved by magnetic resonance imaging.
