Case reportThree-Dimensional Printing of Models for Preoperative Planning and Simulation of Transcatheter Valve Replacement
Section snippets
Comment
TAVI has become a new approach alternative to conventional heart valve replacement in patients in whom open surgical techniques were not possible [1]. Almost all publications conclude that the preoperative assessment of the aortic annulus dimensions is important for correct valve sizing and finally to minimize perioperative complications such as paravalvular aortic regurgitation, valve migration, and ischemic events. However, a gold standard has not been established, and numerous techniques for
