The aim of this study was to compare the immediate outcome of patients undergoing transcatheter (TAVI) versus surgical aortic valve replacement with the sutureless Perceval bioprosthesis (SU-AVR). This is a retrospective multicenter analysis of 773 patients who underwent either TAVI (394 patients, mean age, 80.8 ± 5.5 years, mean EuroSCORE II 5.6 ± 4.9 %) or SU-AVR (379 patients, 77.4 ± 5.4 years, mean EuroSCORE II 4.0 ± 3.9 %) with or without concomitant myocardial revascularization. Data on SU-AVRs were provided by six European institutions (Belgium, Finland, Germany, Italy and Sweden) and data on TAVIs were provided by a single institution (Catania, Italy). In-hospital mortality was 2.6 % after SU-AVR and 5.3 % after TAVI (p = 0.057). TAVI was associated with a significantly high rate of mild (44.0 vs. 2.1 %) and moderate-severe paravalvular regurgitation (14.1 vs. 0.3 %, p < 0.0001) as well as the need for permanent pacemaker implantation (17.3 vs. 9.8 %, p = 0.003) compared with SU-AVR. The analysis of patients within the 25th and 75th percentiles interval of EuroSCORE II, i.e., 2.1-5.8 %, confirmed the findings of the overall series. One-to-one propensity score-matched analysis resulted in 144 pairs with similar baseline characteristics and operative risk. Among these matched pairs, in-hospital mortality (6.9 vs. 1.4 %, p = 0.035) was significantly higher after TAVI. SU-AVR with the Perceval prosthesis in intermediate-risk patients is associated with excellent immediate survival and is a valid alternative to TAVI in these patients.
本研究旨在比较经导管主动脉瓣置换术(TAVI)与使用无缝合Perceval生物瓣膜的外科主动脉瓣置换术(SU-AVR)患者的近期预后。这是一项对773例患者的回顾性多中心分析,这些患者接受了TAVI(394例,平均年龄80.8±5.5岁,平均欧洲心脏手术风险评估系统II 5.6±4.9%)或SU-AVR(379例,77.4±5.4岁,平均欧洲心脏手术风险评估系统II 4.0±3.9%),伴或不伴有同期心肌血运重建。SU-AVR的数据由六个欧洲机构(比利时、芬兰、德国、意大利和瑞典)提供,TAVI的数据由一个机构(意大利卡塔尼亚)提供。SU-AVR术后住院死亡率为2.6%,TAVI术后为5.3%(p=0.057)。与SU-AVR相比,TAVI与轻度(44.0%对2.1%)和中重度瓣周反流发生率显著较高(14.1%对0.3%,p<0.0001)以及永久起搏器植入需求(17.3%对9.8%,p=0.003)相关。对欧洲心脏手术风险评估系统II处于第25和第75百分位数区间(即2.1-5.8%)的患者进行分析,证实了整个系列的研究结果。一对一倾向评分匹配分析产生了144对具有相似基线特征和手术风险的配对。在这些匹配对中,TAVI术后住院死亡率(6.9%对1.4%,p=0.035)显著更高。在中危患者中使用Perceval瓣膜进行SU-AVR与优异的近期生存率相关,是这些患者TAVI的有效替代方案。
