Idiopathic left ventricular outflow tract pseudoaneurysm

Left ventricular outflow tract (LVOT) pseudoaneurysm is a rare occurrence and may produce clinically unpredictable symptoms. A very few cases of LVOT pseudoaneurysm are reported and there has always been a predisposing factor in these reported cases such as history of infective endocarditis, myocardial infarction, prosthetic aortic valve replacement or chest trauma. Our patient did not have the above predisposing conditions. Intra operative transesophageal echocardiography helped patient management and guided the surgical team in securing and isolation of the aneurysmal sac from the LVOT.
