1-Year Real-World Outcomes of TAVR With the Fifth-Generation Balloon-Expandable Valve in the United States.

BACKGROUND

Longer term outcomes of transcatheter aortic valve replacement (TAVR) with the SAPIEN 3 Ultra RESILIA (S3UR) valve over its predecessors have not been reported in a national registry.

OBJECTIVES

The aim of this study was to compare the 1-year clinical and echocardiographic outcomes of the S3UR with those of the SAPIEN 3 (S3) and SAPIEN 3 Ultra (S3U) in the Society of Thoracic Surgeons/American College of Cardiology TVT (Transcatheter Valve Therapy) Registry.

METHODS

From September 2022 to March 2023, patients who underwent native TAVR with the S3UR or the S3 or S3U valve were propensity matched and compared. Predictors of 1-year outcomes were identified. The median follow-up time was 358 days (Q1-Q3: 47-365 days) for the S3UR and 364 days (Q1-Q3: 80-365 days) for the S3 and S3U.

RESULTS

A total of 4,598 S3UR patients were propensity matched with 4,598 and 32,536 S3 and S3U patients. At discharge, effective orifice areas were larger in the S3UR group (P < 0.0001). The lower discharge mean gradient in the S3UR group was maintained at 30 days and 1 year (P < 0.0001 for all). At 1 year, all-cause mortality (7.6% vs 9.7%; HR: 0.8; 95% CI: 0.67-0.93; P = 0.004), mild or greater paravalvular leak (PVL) (15.6% vs 18.5%; HR: 0.82; 95% CI: 0.69-0.97; P = 0.02), and life-threatening bleeding (2.0% vs 2.7%; HR: 0.7; 95% CI: 0.54-0.94; P = 0.03) were lower in the S3UR group. S3UR and mild or greater PVL were predictive of 1-year mortality in the overall cohort and in low-risk patients. Valve reintervention remained rare at 1 year (0.6% vs 0.4%; HR: 1.46; 95% CI: 0.77-2.78; P = 0.25).

CONCLUSIONS

TAVR with the S3UR is associated with superior 1-year clinical outcomes and lower gradients than its predecessors, with less PVL and low valve reintervention. Longer follow-up will determine the durability of the RESILIA technology in the SAPIEN valve platform.
