BACKGROUND: Vascular and bleeding complications are common after transcatheter aortic valve implantation (TAVI) and are associated with worse outcomes. The plug-based Manta (M) vascular closure device (VCD) is a novel option to achieve haemostasis for large-bore arterial access sites. OBJECTIVE: We aimed to compare vascular and bleeding complications between the M-VCD and the established suture-based Perclose ProGlide (P)-VCD. METHODS: From February to September 2019 a total of 578 patients underwent transfemoral TAVI at a single high-volume centre. Access site closure was performed using M-VCD in 195 patients (33.7%) and P-VCD in 383 patients (66.3%). We assessed vascular and access site-related complications as well as bleeding events according to the Valve Academic Research Consortium-2 definition. RESULTS: Overall vascular complications occurred less frequently in the M-VCD group (10.7% vs. 19.0%, p = 0.011) driven by a significantly lower rate of major vascular events (2.0% vs. 6.5%, p = 0.025). Access site-related complications were significantly less frequent in the M-VCD cohort (10.7% vs. 16.6%, p = 0.048). The M-VCD was associated with significantly lower rates of major (0.5% vs. 4.4%, p = 0.009) and life-threatening bleeding (0% vs. 2.3%, p = 0.032). In multivariable analysis, the use of M-VCD was the only independent predictor of vascular complications (odds ratio 0.54, 95% confidence interval 0.32-0.91, p = 0.022). CONCLUSIONS: The M-VCD was associated with a reduction of vascular and access-site complications as well as severe bleeding after transfemoral TAVI compared to the P-VCD in this observational study.
