To demonstrate the feasibility of transfemoral transcatheter aortic valve replacement (TAVR) with the 29 mm Edwards SAPIEN XT valve and Novaflex™ + delivery system through a 20F expandable sheath (eSheath™, Edwards Lifesciences, USA). In addition, to describe the use of the Novaflex + delivery system and expandable sheath.
TAVR has undergone significant advances in device technology resulting in smaller profile sheaths and delivery systems, allowing transfemoral delivery of a 29 mm valve.
Twelve patients underwent transfemoral TAVR with the 29 mm Edwards SAPIEN XT valve and Novaflex + delivery system through a 20F expandable sheath. Baseline clinical and procedural characteristics are evaluated. In-hospital and 30-day outcomes are reported according to Valve Academic Research Consortium criteria.
All patients were male with a mean aortic annulus diameter of 25.0 ± 1.1 mm and 25.9 ± 1.2 mm, on transesophageal echocardiography and multidetector computerized tomography, respectively. Mean iliofemoral minimal luminal diameter (MLD) was 8.0 ± 0.8 mm. Successful deployment of the valve occurred in 11 out of 12 patients. Valve embolization occurred in one patient. Aortic valve area increased from 0.7 ± 0.2 to 2.0 ± 0.5 cm(2) (P < 0.001). There were two major vascular complications; however, there were no in-hospital or 30-day neurological events, need for pacemaker insertion, or mortality.
Transfemoral TAVR with the 29 mm Edwards SAPIEN XT valve and Novaflex + delivery system through a 20F expandable sheath was feasible with acceptable short-term outcomes.
展示经股动脉输送 29 毫米爱德华思派恩 XT 瓣膜和诺华 Flex™+输送系统通过 20F 可扩张鞘(eSheath™,爱德华生命科学公司,美国)进行经股动脉主动脉瓣置换术(TAVR)的可行性。此外,还描述了诺华 Flex+输送系统和可扩张鞘的使用方法。
TAVR 在器械技术方面取得了重大进展,导致鞘管和输送系统的轮廓更小,从而能够通过股动脉输送 29 毫米瓣膜。
12 名患者接受了经股动脉 TAVR,使用 29 毫米爱德华思派恩 XT 瓣膜和诺华 Flex+输送系统通过 20F 可扩张鞘。评估了基线临床和程序特征。根据 Valve Academic Research Consortium 标准报告住院和 30 天的结果。
所有患者均为男性,平均主动脉瓣环直径为 25.0±1.1mm 和 25.9±1.2mm,分别经食管超声心动图和多排计算机断层扫描测量。平均髂股最小管腔直径(MLD)为 8.0±0.8mm。12 名患者中有 11 名成功植入瓣膜。1 名患者发生瓣膜栓塞。主动脉瓣口面积从 0.7±0.2cm²增加至 2.0±0.5cm²(P<0.001)。有 2 例主要血管并发症;然而,没有院内或 30 天的神经事件、需要起搏器植入或死亡率。
经股动脉 TAVR 使用 29 毫米爱德华思派恩 XT 瓣膜和诺华 Flex+输送系统通过 20F 可扩张鞘是可行的,短期结果可接受。
