Fitting a transcatheter mitral valve in a life-sized 3D-printed model of the patients’ left heart. Three-dimensional virtual model was 3D-printed on a 1:1 scale. Calcium printed in blue. (A) Surgical view of the left atrium. A Sapien3 26 mm valve on its delivery system is positioned in the mitral annulus. (B) The transcatheter heart valve after deployment in the mitral annulus, adequately fitted. (C) Transcatheter heart valve viewed from the ventricular side. Pliers advanced from the aorta grasp the anterior mitral leaflet, the neo left ventricular outflow tract is highlighted in red. (D) Transcatheter heart valve with deflected anterior mitral leaflet viewed from the aorta shows modest left ventricular outflow tract obstruction (highlighted in red). AML, anterior mitral leaflet; LA, left atrium; LAA, left atrial appendage; LSPV, left superior pulmonary vein; LVOT, left ventricular outflow tract.
