摘      要：Introduction:Transcatheter aortic valve replacement(TAVR)can have some fatal complications during and after the *** recently,pre-procedural imaging with cardiac computed tomography(CT),which is required to evaluate for TAVR,had its own *** aimed to determine whether 3 D printed models can predict complications when other pre-procedural imaging techniques ***:Vascular center patients with aortic valve stenosis,who died after TAVR between June 2011 and June2016,were enrolled in this retrospective *** CT datasets of the patients were imported into a threedimensional(3 D)construction software and then printed by flexible *** predict complications during and after operations,we designed a release test using the non-valved stent mode that was consistent with the Edwards Sapien XT valve in size and radial support ***:The 3 D model predicted the coronary obstruction and annular rupture in the in vitro release process,which was consistent with what happened in the actual ***:Three-dimensional modeling facilitates pre-operative assessment of patients receiving TAVR,with accurate simulation of intraoperative status.
