Large-bore arterial access closure after transcatheter aortic valve replacement: a systematic review and network meta-analysis.

AIMS: As the indications to transcatheter aortic valve replacement (TAVR) expand to patients at increasingly lower risk, procedure-related vascular and bleeding complications events must be minimized. We aimed to evaluate the impact of different large-bore arterial access closure devices on clinical outcomes after TAVR. METHODS AND RESULTS: We searched for papers that reported outcomes according to the type of vascular closure device/technique used after TAVR and performed a Bayesian network meta-analysis (NMA). Fifteen studies involving 9259 patients who underwent access site closure using PROSTAR™ XL percutaneous vascular surgical system (Abbott Vascular, Santa Clara, CA, USA), Perclose ProGlide™ suture-mediated closure system (Abbott), or MANTATM vascular closure device (Teleflex, Morrisville, NC, USA) were included. NMA showed MANTA to have the highest likelihood of reducing a primary composite endpoint of intra-hospital death, major vascular complications, and major or life-threatening bleedings [surface under the cumulative ranking curve analysis (SUCRA) 94.8%], but this was mitigated when only randomized clinical trials and propensity-matched cohorts were included (SUCRA 56.1%). The ProGlide showed the highest likelihood to reduce major or life-threatening bleedings, especially with increasing procedural complexity, and the MANTA device to reduce major and minor vascular complications. The ProStar XL device performed poorly in all explored endpoints. CONCLUSION: Available evidence summarized through a NMA shows that ProGlide and MANTA devices appear to be both valid vascular closure devices globally and to be the best options to minimize vascular complications and reduce bleeding in patients undergoing TAVR, respectively.
