(Top left) Stentless Shelhigh valve (Shelhigh) in aortic position viewed from transesophageal position. (Top right) M-mode color Doppler echocardiography demonstrates flow inside the valve. (Bottom) Schematic presentation. Note coronary flow in right coronary sinus and artery (R Coro). (Diast = flow in diastole; Flow = Doppler flow in systole in two-dimensional echocardiography; Syst = flow in systole.)
