Incomplete occlusion of left ventricular aneurysms after endoventricular aneurysmorrhaphy: diagnosis by echocardiography and ventriculography.

Surgical treatment of left ventricular aneurysms have recently focused on maintaining normal left ventricular geometry by using a circular patch repair to exclude the aneurysmal cavity (endoaneurysmorrhaphy). We describe two patients who underwent this procedure and were subsequently found by echocardiography and angiography to have a residual communication between the left ventricular cavity and the aneurysm which contained thrombus. This finding may have implications regarding the optimal hemodynamic result of the surgery and the risk of thromboembolism.
