Surgical treatment of left ventricular aneurysm with acute myocardial infarction associated to mitral valve stenosis: a case report

A 55-year-old female afflicted with mitral valve stenosis and atrial fibrillation was admitted to our hospital complaining of chest pain, ST elevation of ECG (V2-5) and elevated CPK value were recognized. She was diagnosed as having acute myocardial infarction, and percutaneous transluminal coronary recanalization was performed immediately. The coronary angiogram showed occlusion by the thrombus at the proximal left anterior descending branch (#7), even, left ventriculogram showed ventricular aneurysm on the anterior wall. But these lesions could not be recanalized by 960,000 IU urokinase administration. She underwent aneurysmectomy and mitral valve replacement with 27 mm SJM prosthesis. When mitral valve stenosis accompanied with left ventricular aneurysm we considered in order to improve left ventricular function, it is necessary to undergo not only mitral valve operation but left ventricular aneurysmectomy aggressively.
