Giant Aneurysm of Left Main Coronary Artery in a Patient With Prior Operation for 4-Valve Endocarditis

Islam Abudayyeh et al. Tex Heart Inst J. .

Abstract

Left main coronary artery aneurysm is an unusual complication of infective endocarditis. Although this type of aneurysm is often asymptomatic, rupture and thrombus formation that result in myocardial infarction are known complications; therefore, prompt recognition and surgical intervention are warranted. This report describes a patient who presented with a giant left main coronary artery aneurysm 3.5 years after being treated for 4-valve endocarditis. The management and technical aspects of this challenging case are discussed here.

Keywords: Mycotic aneurysm; coronary aneurysm; endocarditis.
