RESUMO
We report on the case of a 65-year-old man with unstable angina due to a left anterior descending (LAD) coronary artery single aneurysm. On a beating heart, the aneurysm was partially resected and the left internal thoracic artery was grafted in situ as a patch to the LAD opening. The patient remains well and free of symptoms two years after the operation.

Posterior non-ischemic left ventricular aneurysms are unusual aneurysms of different etiology that develop adjacent to the mitral valve annulus causing mitral regurgitation and progressive heart failure. Surgical correction is mandatory and involves repair of the aneurysm along with repair or replacement of the mitral valve. Two cases of posterior non-ischemic left ventricular aneurysms are reported. Both patients were females (19 and 9 years old) and they presented with symptoms of progressive heart failure. Definite diagnosis was made with transesophageal echocardiography (TEE) and confirmed with left ventriculography. Both patients were successfully treated by surgery. The first patient underwent repair of the aneurysm from inside the left ventricle and mitral valve replacement. The second patient had resection of the aneurysm through an extracardiac route. Both patients are in NYHA class 1, 5 and 4 years respectively after their operation with no evidence of mitral valve dysfunction. Posterior non-ischemic left ventricular aneurysms can securely be diagnosed by TEE and angiocardiography. Surgical treatment is mandatory in order to forestall potential life threatening cardiovascular events and should be tailored to the operative findings.
