Abstract
One of the most profitable applications of intraoperative TEE is evaluating the anatomy and function of the atrioventricular valves during repair of atrioventricular septal defects (AVSD). Surgical correction closes the ASD and ventricular septal defect (VSD) with a patch and reconstructs the atrioventricular valve. Two-dimensional echocardiography allows the study of leaflet motion before and after valve reconstruction. Residual shunts and valve regurgitation can be detected by color Doppler flow imaging. Two forms can be distinguished: partial, or ostium primum ASD, and complete AVSD. Three anatomic types of complete AVSD can be distinguished according to the morphology of the atrioventricular valve: type A, type B type C.
