Key Points TMVR can cause fatal LVOT obstruction, especially in the setting of valve‐in‐mitral annular calcification. A predicted neoLVOT of <190 mm 2 , measured using computer aided design models of 3‐D datasets with a virtual valve implant, portends a high risk of LVOT obstruction following TMVR. NeoLVOT predictions may be based on different valve implantation depths, and do not account for body mass, complex neoLVOT time‐varying three‐dimensional geometry, flow, or anterior mitral leaflet dynamics.
