BACKGROUND

The latest iterations of devices for transcatheter aortic valve replacement (TAVR) have brought refinements to further improve patient outcomes.

OBJECTIVES

This study sought to compare early outcomes of patients undergoing TAVR with the self-expanding (SE) Evolut PRO/PRO+ or balloon-expandable (BE) Sapien 3 ULTRA devices.

METHODS

The OPERA-TAVI registry collected data from 14 high-volume centers worldwide on patients undergoing TAVR with SE or BE devices. After excluding patients who were not eligible to both devices, patients were compared using 1:1 propensity score matching. The primary efficacy and safety outcomes were VARC-3 device success and early safety, respectively.

RESULTS

Among 2,241 patients eligible for the present analysis, 683 pairs of patients were matched. The primary efficacy outcome did not differ between patients receiving SE or BE transcatheter aortic valves (SE: 87.4% vs BE: 85.9%; P = 0.47), but BE device recipients showed a higher rate of the primary safety outcome (SE: 69.1% vs BE: 82.6%; P < 0.01). This finding was driven by the higher rates of permanent pacemaker implantation (PPI) (SE: 17.9% vs BE: 10.1%; P < 0.01) and disabling stroke (SE: 2.3% vs BE: 0.7%; P = 0.03) in SE device recipients. On post-TAVR echocardiography, the rate of moderate-to-severe paravalvular regurgitation was similar between groups (SE: 3.2% vs BE: 2.3%; P = 0.41), whereas lower mean transvalvular gradients were observed in the SE cohort (median SE: 7.0 vs BE: 12.0 mm Hg; P < 0.01).

CONCLUSIONS

The OPERA-TAVI registry showed that SE and BE devices had comparable VARC-3 device success rates, but the BE device had a higher rate of early safety. The higher PPI and disabling stroke rates in SE device recipients drove this composite endpoint.
