Fig. 3From: Simulation of semilunar valve function: computer-aided design, 3D printing and flow assessment with MRTop Panel: 3D printed tricuspid aortic valve phantom. a Superior view looking down the ascending aorta to visualize the aortic valve leaflets. b Inferior view looking up the left ventricular outflow tract to the base of the closed valve. c Lateral view of aortic valve phantom incorporating aortic root structures. Bottom Panel: Piping connected to phantom which attaches to the physiological MRI compatible pump. Red arrows show the direction of flow through the phantomBack to article page
