Minimally invasive transatrial repair of posterior left ventricular aneurysm.

Left ventricular aneurysms (LVA) are a complication of myocardial infarction, that rarely involve the posterior wall; surgical repair of posterior LVA poses a technical challenge when associated with concomitant mitral regurgitation. We describe a minimally invasive treatment of ischemic MR and concomitant patch exclusion of posterior LVA through a right minithoracotomy. Using a transatrial approach, the aneurysm is closed with a "U" shaped dacron patch, whose base is anchored to the mitral annulus. Two patients were operated by this method with excellent results.
