Currently, there is no preference for surgical (SAVR) vs transcatheter (TAVR) aortic valve replacement in patients with low ejection fraction (EF). The present study retrospectively compared the outcomes of SAVR vs TAVR in patients with EF ≤40% (70 SAVR and 117 TAVR patients). Study outcomes were survival and the composite endpoint of stroke, aortic valve reintervention, and heart failure readmission. The patients who had TAVR were older (median: 75 (25-75th percentiles: 69-81) vs 51 (39-66) years old; < .001) with higher EuroSCORE II (4.95 (2.99-9.85) vs 2 (1.5-3.25); < .001). Postoperative renal impairment was more common with SAVR (8 (12.5%) vs 4 (3.42%); = .03), and they had longer hospital stay [9 (7-15) vs 4 (2-8) days; < .001). There was no difference between groups in stroke, reintervention, and readmission (Sub-distributional Hazard ratio: .95 (.37-2.45); = .92). Survival at 1 and 5 years was 95% and 91% with SAVR and 89% and 63% with TAVR. Adjusted survival was comparable between groups. EF improved significantly (β: .28 (.23-.33); < 0.001) with no difference between groups ( = .85). In conclusion, TAVR could be as safe as SAVR in patients with low EF.
目前,对于射血分数(EF)较低的患者,外科主动脉瓣置换术(SAVR)与经导管主动脉瓣置换术(TAVR)之间没有偏好。本研究回顾性比较了 EF≤40%的患者行 SAVR 与 TAVR 的结局(70 例 SAVR 患者和 117 例 TAVR 患者)。研究结局为生存率和卒中和主动脉瓣再介入以及心力衰竭再入院的复合终点。行 TAVR 的患者年龄更大(中位数:75(25-75 百分位:69-81)比 51(39-66)岁;<0.001),EuroSCORE II 评分更高(4.95(2.99-9.85)比 2(1.5-3.25);<0.001)。术后肾功能不全在 SAVR 中更为常见(8(12.5%)比 4(3.42%);=0.03),且住院时间更长[9(7-15)比 4(2-8)天;<0.001]。两组之间在卒中和再介入以及再入院方面无差异(亚分布风险比:0.95(0.37-2.45);=0.92)。SAVR 的 1 年和 5 年生存率分别为 95%和 91%,TAVR 的 1 年和 5 年生存率分别为 89%和 63%。调整后的生存率在两组之间无差异。EF 明显改善(β:0.28(0.23-0.33);<0.001),两组之间无差异(=0.85)。总之,在 EF 较低的患者中,TAVR 与 SAVR 一样安全。
