With transcatheter aortic valve implantation (TAVI) rapidly spreading its indication to lower-risk and younger patients, reliable and reproducible guidance on how to orient the transcatheter heart valve (THV) to avoid coronary overlap and improve haemodynamic performance becomes an urgent need. It has recently been suggested that the orientation of the neo-commissures during the navigation of the delivery system could be correlated with their final position in the aortic annulus and, consequently, modified to improve final THV orientation1. However, no previous study has considered the effect of different aorta angulations and how to add this variable to a neo-commissure ...
