Background Significant postprocedural aortic regurgitation (AR) is observed in 10% to 20% of cases after transcatheter aortic valve replacement (TAVR). The prognostic value and the predictors of such a complication in balloon-expandable (BE) and self-expandable (SE) TAVR remain unclear.Methods and Results TAVR was performed in 3195 consecutive patients at 34 hospitals. Postprocedural transthoracic echocardiography was performed in 2769 (92%) patients of the eligible population, and these patients constituted the study group. Median follow-up was 306 days (Q1-Q3=178-490). BE and SE devices were implanted in 67.6% (n=1872) and 32.4% (n=897). Delivery was femoral (75.3%) or nonfemoral (24.7%). A postprocedural ARgrade 2 was observed in 15.8% and was more frequent in SE (21.5%) than in BE-TAVR (13.0%, P=0.0001). Extensive multivariable analysis confirmed that the use of a SE device was one of the most powerful independent predictors of postprocedural ARgrade 2. For BE-TAVR, 8 independent predictors of postprocedural ARgrade 2 were identified including femoral delivery (P=0.04), larger aortic annulus (P=0.0004), and smaller prosthesis diameter (P=0.0001). For SE-TAVR, 2 independent predictors were identified including femoral delivery(P=0.0001). Aortic annulus and prosthesis diameter were not predictors of postprocedural AR for SE-TAVR. A postprocedural ARgrade 2, but not a postprocedural AR=grade 1, was a strong independent predictor of 1-year mortality for BE (hazard ratio=2.50; P=0.0001) and SE-TAVR (hazard ratio=2.11; P=0.0001). Although postprocedural ARgrade 2 was well tolerated in patients with ARgrade 2 at baseline (1-year mortality=7%), it was associated with a very high mortality in other subgroups: renal failure (43%), AR
