ABSTRACT

Obstruction to pulmonary blood flow in complete transposition of the great arteries (TGA) can be dynamic or anatomic. Gradients measured preoperatively across the left ventricle outflow tract (LVOT) by Doppler echocardiography may overestimate the degree of anatomic obstruction as a result of the greatly increased pulmonary blood flow in children with TGA, especially with an associated ventricular septal defect (VSD). It is imperative, therefore, that the pathophysiologic processes involved in left ventricular outflow tract obstruction (LVOTO) be fully evaluated using intraoperative real time transesophageal echocardiography (TEE) in order to make a safe surgical decision. Here, we present a case of TGA VSD with LVOTO which needed muscle bundle resection along with arterial switch operation (ASO) which is guided by intraoperative real time TEE which helping in differentiating anatomic from dynamic LVOTO.
