Abstract

Background: Mitral valve transcatheter edge-to-edge repair (M-TEER) has historically been considered more challenging in the commissural regions of the mitral valve (A1P1, A3P3) compared to central regions (A2P2). Data on outcomes with contemporary M-TEER by implant location are limited. Methods: Degenerative mitral regurgitation (DMR) patients treated with the PASCAL Precision system between Sep 2022-Oct 2024 using a single PASCAL or PASCAL Ace implant were analyzed by device location (A2P2 vs non-A2P2) from the STS/ACC TVT Registry. Procedural, clinical, and echocardiographic outcomes to 30 days were assessed. All outcomes were site-reported. Results: The study comprised 1207 patients categorized into two groups: patients with a single implant at A2P2 (n=977) and those with a single implant at non-A2P2 position (n=230). Patients in the A2P2 group were younger, majority female, had lower incidence of flail leaflet, and a higher incidence of heart failure hospitalization (HFH) and leaflet calcification. There were no aborted procedures in either group, and successful device implantation was achieved in a high proportion of patients, 98.2% in the A2P2 group vs. 97.0% in the non-A2P2 group (P=0.299). Procedure duration was shorter in the A2P2 group (77.0 min) vs. non-A2P2 group (86.0 min) (P=0.053). The PASCAL Ace implant was used more frequently in the non-A2P2 group (87.4%) compared to A2P2 group (67.0%) (P<0.001). At 30 days, the incidence of adverse events was low and comparable in both the A2P2 and non-A2P2 groups [mortality: 1.9% vs. 2.6%; mitral valve reintervention: 0.3% vs. 0%; HFH: 1.6% vs. 3.0%; single leaflet device attachment (SLDA): 0.1% vs. 0.4%; all P>0.05]. MR reduction at 30 days was similar in the A2P2 vs non-A2P2 groups (P=0.997) with MR≤2+ and MR≤1+ rates of 94.9% vs. 95.8% and 72.0% vs. 74.3%, respectively. Conclusion: In a real-world setting, DMR patients treated with the PASCAL Precision system in both commissural and non-commissural implant locations experienced high survival, significant MR reduction and low incidence of adverse events, including SLDA, HFH and mitral valve reintervention at 30 days.
