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.

小主动脉环中最新一代球囊扩张和自扩张经导管心脏瓣膜之间的瓣膜性能。



背景 与球囊扩张瓣膜 (BEV) 相比,使用自扩张瓣膜 (SEV) 的经导管主动脉瓣置换术 (TAVR) 在小主动脉环 (SAA) 中可促进更好的血流动力学。目的 作者试图比较最新一代 BEV 和 TAVR 后 SEV for SAA 的血流动力学特性和临床结果。方法 我们回顾性分析了 1,227 例接受 TAVR 治疗主动脉瓣狭窄伴 SAA(定义为瓣环面积 ≤430 mm2)的患者,使用 BEV (SAPIEN3 Ultra RESILIA,Edwards Lifesciences) 和 SEV (Evolut FX,Medtronic)。使用 logistic 回归和倾向评分分析评估瓣膜设计对严重人工体-患者错配、主动脉瓣平均压力梯度 ≥20 mm Hg、轻度瓣周渗漏 (PVL) ≥轻度、新的永久性起搏器植入 (PMI) 和改良 VARC-3 装置出院成功率的影响。结果 在 1,227 例患者中,798 例 (65.0%) 接受了 TAVR 联合 BEV 植入。与使用 SEV 相比,使用 BEV 的 TAVR 的严重假体-患者错配率相对较高 (OR: 1.74;95% CI: 0.54-5.62) 和平均压力梯度 ≥20 mm Hg 的发生率显著更高 (OR: 2.05;95% CI: 0.91-4.62)。相比之下,BEV 显示轻度 (OR: 0.19;95% CI: 0.14-0.26) 和新发 PMI (OR: 0.53;95% CI: 0.33-0.86) ≥ PVL 发生率显著降低。BEV 和 SEV 之间的设备成功率相当。这些结果通过倾向得分分析得到证实。结论在 SAA 的 TAVR 中,SEV 的血流动力学优于最新的 BEV,而最新的 BEV 在轻度和新发 PMI ≥ PVL 发生率低于 SEV。
