Figure 1 (A) Echocardiography of the aorta revealed the stenosis at the sinutubular junction level with a diameter of 4.7 mm and BAV with mild aortic regurgitation. (B) Echocardiography on the atrium level suggested SASD and mild pulmonary arterial hypertension. (C, D and F) CT and three-dimensional reconstruction confirmed the significant SVAS and demonstrated the absence of right coronary artery. (E) Left coronary origin was above the level of Valsalva sinus and demonstrated features of stenosis at the ostium. (G and H) Exploration during surgery revealed that main branch of the right coronary artery was present but not connected to the aorta.
