Concurrent submitral left ventricular aneurysm and an aneurysm of the sinus of valsalva: report of a case.

We herein describe a rare case of a concurrent submitral left ventricular (LV) aneurysm and an aneurysm of the sinus of Valsalva in a 65-year-old Japanese woman. The patient had a history of mitral valve replacement (MVR) for mitral regurgitation caused by a submitral LV aneurysm at the age of 58. At the time of the MVR, the orifice of the submitral LV aneurysm without thrombi was beneath the posterior leaflet, but surgical repair of the submitral LV aneurysm was not attempted. Although the patient was asymptomatic, when she underwent an echocardiogram at 65 years of age an aneurysm of the noncoronary sinus of Valsalva was detected. However, echocardiography performed before the initial operation had shown that the aneurysm of the sinus of Valsalva was coexistent with the submitral LV aneurysm. Since the submitral LV aneurysm revealed no progressive enlargement during the 7 years, patch closure of the aneurysm of the sinus of Valsalva alone was successfully performed.
