title: Left ventricular outflow tract false aneurysm late after aortic valve replacement.
abstract: We describe an unusual case of left ventricular outflow tract (LVOT) pseudoaneurysm late after aortic valve replacement. A 77-year-old man, who had undergone aortic valve replacement with mechanical prosthesis 7 years ago, presented, asymptomatic, with a transesophageal echocardiography (TTE) diagnosis of a large cavitary mass arising behind the aortic wall. The orifice of the pseudoaneurysm was successfully surgically closed and the aortic root reconstructed with cryopreserved homograft.
