Repair of posterior left ventricular aneurysm through transatrial approach

Repair of posterior left ventricular ischemic aneurysms implies an extracardiac approach to reshape the ventricular geometry frequently associated with mitral surgery. A transatrial technique was described for lesions following mitral surgery or for subvalvular idiopathic cases. A transmitral approach was used for ischemic or traumatic pseudoaneurysm. We describe a case of postinfarction posterior true aneurysm with associated mitral incompetence. Both lesions were treated through an intracardiac approach. The posterior mitral leaflet was detached posteriorly to close the aneurysm with a patch, and the valve replaced sparing all subvalvular apparatus. This technique seems to be safe and allows to treat both lesions avoiding ventriculotomy.
