DYNAMIC LEFT VENTRICULAR OUTFLOW TRACT OBSTRUCTION COMPLICATING AORTIC VALVE REPLACEMENT: A HIDDEN MALEFACTOR REVISITED

Dynamic left ventricular outflow tract obstruction complicating aortic valve replacement: A hidden malefactor revisited

It is known that a dynamic left ventricular outflow tract (LVOT) obstruction exists in patients, Compressor Motor Start Relay following aortic valve replacement (AVR) and is usually considered to be benign.We present a patient with dynamic LVOT obstruction following AVR, who developed refractory cardiogenic shock and expired inspite of various trea
