MANTA Versus Suture-based Closure Devices Following Transcatheter Aortic Valve Replacement: An Updated Meta-analysis.

BACKGROUND

Vascular access closure is essential in large-bore arteriotomy procedures, such as transcatheter aortic valve replacement. ​Suture-based devices are frequently used for vascular access closure. MANTA (Teleflex) is a collagen plug-based device used to achieve hemostasis with evolving efficacy and safety data. This study aimed to evaluate plug-based versus suture-based closure devices following large-bore arteriotomy procedures.

METHODS

We conducted a systematic review searching PubMed, Cochrane Library, and ClinicalTrials.gov (inception through November 2021) for studies evaluating plug-based versus suture-based closure devices following large-bore arteriotomy procedures. We performed a meta-analysis comparing the length of stay, device failure, mortality, bleeding, and vascular complications between these 2 types of devices.

RESULTS

Eleven studies (2 randomized controlled trials and 9 observational studies) with a total of 3123 patients were included in this analysis. Compared with suture-based devices, plug-based devices were associated with a significant decrease in the length of stay (standardized mean difference: -0.14; 95% CI, -0.25 to -0.03) and vascular closure device failure (odds ratio, 0.63; 95% CI, 0.44-0.91) following the procedure. There were no significant differences in all-cause mortality, major or minor bleeding, and major or minor vascular complications between plug-based and suture-based closure devices.

CONCLUSIONS

Plug-based vascular closure devices were associated with a shorter length of stay and lower risk of device failure following large-bore arteriotomy procedures without differences in mortality, bleeding, or vascular complications than suture-based closure devices.
