Abstract

Subaortic left ventricular aneurysm is a rare, mostly congenital condition, and occurs as a result of a defect in the alveolar fibrosa between the mitral and aortic annuli. Clinically, most subaortic left ventricular aneurysms are asymptomatic, but some of them cause arrhythmia, chest pain, and even sudden cardiac death. We report an autopsy case of sudden cardiac death due to subaortic left ventricular aneurysm in a 38-year-old male sailor.

(A, B) A subaortic left ventricular aneurysm is located below the posterior leaflet of the aortic valve. (C) The aneurysm has the shape of ‘8’ and extends between the aorta and left atrium. A thrombus is observed in the aneurysm. Ao, aorta; LA, left atrium; An, aneurysm; LC, left coronary artery; LV, left ventricle.
