Subvalvular left ventricular aneurysms. A report of 5 Ugandan cases

Abstract

The pathological features of 5 cases of subvalvular cardiac aneurysms occurring in Uganda over a 13 year period are described; 3 were subaortic and 2 were submitral. One of the latter was atypical in that the aneurysm arose at some distance below the fibrous mitral ring and was associated with endomyocardial fibrosis. In 2 cases where the coronary sinus and its ostium was examined, no abnormality was detected. Previous descriptions of the pathological aspects of subvalvular aneurysms are briefly reviewed.
