BACKGROUND: Transcatheter aortic valve replacement (TAVR) using a self-expandable valve (SEV) promotes better hemodynamics compared with a balloon-expandable valve (BEV) in a small aortic annulus (SAA).
OBJECTIVES: The authors sought to compare hemodynamic properties and clinical outcomes between the latest-generation BEV and SEV after TAVR for SAA.
METHODS: We retrospectively analyzed 1,227 patients undergoing TAVR for aortic stenosis with SAA, defined as an annulus area ≤430 mm2, using the BEV (SAPIEN3 Ultra RESILIA, Edwards Lifesciences) and SEV (Evolut FX, Medtronic). The impact of valve design on severe prosthesis-patient mismatch, aortic valve mean pressure gradient ≥20 mm Hg, paravalvular leakage (PVL) ≥ mild, new permanent pacemaker implantation (PMI), and modified VARC-3 device success at discharge was evaluated using logistic regression and propensity score analysis.
RESULTS: Of 1,227 patients, 798 (65.0%) underwent TAVR with BEV implantation. TAVR using BEV had a relatively higher rate of severe prosthesis-patient mismatch (OR: 1.74; 95% CI: 0.54-5.62) and significantly higher incidence of mean pressure gradient ≥20 mm Hg (OR: 2.05; 95% CI: 0.91-4.62) than that using SEV. By contrast, the BEV showed significantly lower incidence of PVL ≥ mild (OR: 0.19; 95% CI: 0.14-0.26), and new PMI (OR: 0.53; 95% CI: 0.33-0.86). The rate of device success was comparable between the BEV and the SEV. These results were confirmed by propensity score analysis.
CONCLUSIONS: In TAVR for SAA, SEV demonstrated better hemodynamics than the latest BEV, whereas the latest BEV had lower incidences of PVL ≥ mild and new PMI than the SEV.
