case_images: Mid-esophageal aortic valve short-axis view on transesophageal echocardiography showing a "rectangular" opening of the quadricuspid aortic valve during systole (a) and an "x" or cross-shaped appearance during diastole (b). Cusp 1: left coronary, cusp 2: right coronary, cusp 3: noncoronary, cusp 4: accessory cusp

case_images: Preoperative transthoracic echocardiography has reported a tricuspid aortic valve; however, intraoperative transesophageal echocardiography (TEE) showed a QAV in mid-esophageal aortic valve short-axis view [Figure 1a and 1b, Video 1]. The left and right coronary cusps (1 and 2) were large, while the noncoronary and accessory cusps (3 and 4) were smaller in size, making it type "C" QAV according to the Hurwitz and Roberts classification [Figures 1 and 2].
