The impact of pre-existing peripheral artery disease on transcatheter aortic valve implantation outcomes: A systematic review and meta-analysis.

Peripheral arterial disease (PAD) plays a decisive role in the preinterventional selection process of the optimal vascular access site in patients undergoing transcatheter aortic valve implantation (TAVI). However, the impact of PAD on mortality and vascular complications (VCs) in TAVI-treated patients remains unclear. Accordingly, we aimed to assess the outcomes of patients with and without PAD undergoing TAVI, by performing a meta-regression analysis.
