PC flow measurements in-vitro and in-vivo including a synthetic aortic valve model, two biological and one mechanical aortic valve prosthesis. a. Flow measured in-vitro over the distance to the valve. b. Flow measured in-vivo over the distance to the valve. c In-vivo: Long axis view (Cine-imaging, steady state free precession) showing the left ventricular outflow tract and the position of the aortic prosthesis (white arrow). d In-vivo: cine imaging of the aortic valve location (left) and ascending aorta in the area of the suspected restored flow 26.4 mm distal to the aortic valve (right) for each subject (columns)
