Functional Assessment in TAVI: FAITAVI

"The Angiographically-guided strategy is that of aiming the most complete degree of revascularization based on angiographic evaluation (stenting all coronary stenosis of major branches \>2.5mm, with a % coronary stenosis\>50% as evaluated by visual estimation.~The Physiologically-guided strategy is that of treating only lesions with FFR ≤0.80, and leaving on optimal medical treatment lesions with FFR \>0.80. The iFR values will be recorded in all patients, and verified in the core laboratory to allow a post-hoc analysis correlating the 0.80 FFR cut-off with different iFR cut-off values, and using the same study end-points.~Particular attention will be dedicated to the eventual occurrence of clinical events in patients deferred on the bases of FFR values \>0.80 that show a discrepancy with positive (\<0.89) iFR values to investigate the reliability of the FFR in the aortic stenosis setting. Both groups will receive the same TAVI strategy and optimal medical therapy"
