Answer

Preoperative assessment of coronary artery disease (CAD) is essential to determine the need for concomitant coronary artery bypass grafting (CABG). Transesophageal echocardiography (TEE) is crucial preoperatively to examine the need for aortic valve replacement. Patients with aortic stenosis or aortic insufficiency in whom the valve leaflets are anatomically abnormal require replacement, whereas patients with aortic insufficiency and normal aortic valve leaflets may be candidates for valve-sparing procedures. TEE is valuable for accurate delineation of the aortic root at the sinuses of Valsalva and sinotubular junction.
