Objectives: This study aimed to assess the feasibility of percutaneous arterial access site closure after percutaneous transfemoral transcatheter aortic valve implantation (TF-TAVI) using single versus double Perclose ProGlide devices. Backgrounds: Although suturing with the preclose technique has been widely adopted during TF-TAVI, the optimal vascular closure strategy is still under debate. Methods: Data from 279 patients who underwent TF-TAVI, obtained from the Optimized CathEter vAlvular iNtervention (OCEAN-TAVI) Japanese multicenter registry. Technical, procedural, and clinical outcomes were compared between the single ProGlide group (n=99) and double ProGlide group (n=180). They were also analyzed by propensity adjusted matching model (single [n=69] vs. double [n=69]). All patients were treated through a 16-Fr to 20-Fr eSheath. Technical success of the closure device was defined as hemostasis not requiring alternative invasive treatment. Access site-related vascular complications, bleedings, and other procedural complications were defined according to the Valvular Academic Research Consortium-2 (VARC-2) criteria. Results: The rates of technical success and access site-related vascular complications were similar in the 2 groups (94.9% vs. 91.6%, p=0.44; 5.0% vs. 7.7%, p=0.54, respectively). The prevalence of bleeding complications did not differ between the 2 groups (1.0% vs. 3.3%, p=0.43). Thirty-day mortality rate also showed no difference between the 2 groups (2.0% vs. 1.1%, p=0.95), although these events were not associated with access site failure. These results were not attenuated in the propensity matching model. Conclusions: Vascular closure with a single ProGlide in TF-TAVI could achieve equivalent, acceptable rates of technical success and procedural complications compared with the double ProGlide technique.
