Subvalvular left ventricular aneurysms

Subvalvular left ventricular aneurysms can be subaortic or submitral with v ariable etiology. This is a retrospective study of 19 subvalvular aneurysms seen in 16 cases. There were 12 isolated subaortic aneurysms, 3 isolated s ubmitral aneurysms, and in 1 case with multiple subaortic and submitral ane urysms. Subaortic aneurysms were associated with infective endocarditis, wh ile there seems to be a strong association between submitral aneurysms and tuberculosis. Five cases of subvalvular aneurysm has associated aneurysm si nus of Valsalva-this association suggests a congenital weakness in the atta chment of aortic and mitral annuli to the underlying myocardium.
