Simulation of transcatheter aortic valve (AV) implantation (TAVI) on three-dimensional (3D) printed models were performed in 3 patients with high risk anatomy for coronary obstruction (CO). Patient 1 had a narrow sinus (29.2mm) and low coronary height (7.3mm); patient 2 had a low coronary height (6.4mm) and a horizontal aorta (71°); patient 3 had an externally-mounted bioprosthesis (TrifectaTM, Abbott) undergoing valve-in-valve procedure. Digital models of the AV, aortic root and bioprosthesis were created using dedicated software (Mimics 19.0) based on computed-tomography (CT) datasets (Figure A1, B1 &C1).
