Current study population was 2993 patients with severe AS enrolled in the CURRENT AS Registry-2 (2581 patients from 10 TAVI centers; 412 patients from 10 non-TAVI centers). TAVI centers more frequently opted for the initial aortic valve replacement (AVR) strategy compared to non-TAVI centers (60% and 40%, P < 0.001). Among patients with the initial AVR strategy, TAVI centers disproportionately favored the initial TAVI strategy compared to non-TAVI centers (71% and 23%, P < 0.001). No significant differences were observed in the risk of a composite of all-cause death or heart failure hospitalization between TAVI and non-TAVI centers in the entire study population (cumulative 3-year incidence: 32.0% and 31.0%, P = 0.37; adjusted hazard ratios: 0.92, 95% confidence intervals: 0.74-1.15, P = 0.45) or in conservative, initial AVR, initial surgical AVR, and initial TAVI strata. A substantial disparity exists in the treatment strategies for patients with severe AS between TAVI and non-TAVI centers. TAVI centers tended to perform AVR, particularly TAVI, earlier and more frequently.

We assessed the hemodynamic performance of supra-annular SAPIEN 3 valve implantation. This retrospective study involved consecutive patients who underwent transcatheter aortic valve replacement (TAVR) using the SAPIEN 3. The device implantation depth and transcatheter heart valve (THV) leaflet-nadir position were angiographically analyzed, and supra-annular implantation was defined as a higher leaflet-nadir position than the original annular line. The Doppler hemodynamic status was evaluated at patient discharge. Among 184 patients, 120 (65%) underwent supra-annular implantation, and their mean implantation depth was significantly lower than that of intra-annular implantation (1.1 vs. 5.2 mm, p < 0.001). No patients developed valve embolization or coronary occlusion, and none required the TAV-in-TAV procedure. Two (1.6%) patients in the supra-annular implantation group had a mild or greater paravalvular leak. Echocardiography demonstrated that supra-annular implantation had better hemodynamic performance, showing a larger indexed effective orifice area (iEOA) compared with intra-annular implantation (1.09 vs. 0.97 cm²/m², p < 0.01). There was a weak but negative correlation between the implantation depth and iEOA (r =  - 0.27, p < 0.01).
