Submitral Aneurysm: An Unusual Aneurysm of the Left Ventricle.

We report a case of a 42-year-old man with a submitral aneurysm who presented to the emergency room in circulatory collapse, with left ventricular obstruction and severe mitral valve stenosis and regurgitation secondary to the aneurysm. Resection of the aneurysm and mitral valve replacement were performed through a median sternotomy without any complication and with good results.
