Background. Vascular complications (VCs) are commonly observed after transfemoral transcatheter aortic valve implantation (TAVI) procedures. Closure devices for the access site were developed to reduce their incidence. We aim to evaluate the prevalence, predictors, and outcomes of the occurrence of post-TAVI VCs. Materials and Methods. A retrospective study was conducted on 1336 consecutive patients who underwent TAVI at the University Hospital of Toulouse, France, between January 2016 and March 2020. All included procedures were performed through the common femoral artery, and ProGlide^® was the used closure device. The studied population was divided into two groups depending on the occurrence of VCs defined according to Valve Academic Research Consortium-2 criteria. Results. The mean age of the studied population was 84.4 ± 6.9, and 48% were male. 90% of TAVI interventions were performed through the right femoral artery. The prevalence of VCs was 18.8%, and 3.7% were major. Prolonged procedure duration was an independent predictor of VCs. Using the right access site and smaller introducer size (14 Fr) were preventive factors. No significant difference in mortality rate was detected between the two groups. Conclusion. This study showed a low prevalence for post-TAVI VCs, especially for the major type. An increase in bleeding events and prolonged cardiac care unit stay were the common adverse outcomes.

现实生活中经导管主动脉瓣植入术后血管并发症的发生率

背景。经股经导管主动脉瓣植入 (TAVI) 手术后通常会观察到血管并发症 (VC)。开发了用于访问站点的封闭装置以减少其发生率。我们旨在评估 TAVI 后 VC 的发生率、预测因素和结果。材料和方法。对 2016 年 1 月至 2020 年 3 月期间在法国图卢兹大学医院接受 TAVI 的 1336 名连续患者进行了一项回顾性研究。所有纳入的手术均通过股总动脉进行，ProGlide ^®是使用的闭合装置。根据 Valve Academic Research Consortium-2 标准定义的 VC 的发生率，将研究人群分为两组。结果。研究人群的平均年龄为 84.4 ± 6.9，其中 48% 为男性。90% 的 TAVI 干预是通过右股动脉进行的。VCs 的患病率为 18.8%，主要为 3.7%。手术时间延长是 VC 的独立预测因素。使用正确的进入部位和较小的引入器尺寸 (14 Fr) 是预防因素。两组之间的死亡率没有显着差异。结论。这项研究表明，TAVI 后 VC 的患病率较低，尤其是主要类型。出血事件增加和心脏监护病房逗留时间延长是常见的不良结局。
