Successful management of an unruptured mycotic coronary aneurysm

Systemic complications of native-valve endocarditis include embolism, abscess formation and development of mycotic aneurysms. To date, only two cases of mycotic coronary aneurysm (MCA) detected by transesophageal echocardiography (TEE) have been reported since 1812. We describe the successful management of infectious mitral valve endocarditis complicated by a MCA involving the left circumflex artery initially detected by TEE. This report illustrates the importance of correlating findings between TEE and coronary angiography, as early detection and prompt management of these rare coronary aneurysms are of paramount importance.
