Idiopathic left ventricular outflow tract pseudoaneurysm

Annals of Cardiac Anaesthesia, 2013
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
