Long-term survival after transcatheter versus surgical aortic valve replacement for aortic stenosis: A meta-analysis of observational comparative studies with a propensity-score analysis

Objectives To synthesize evidence regarding long‐term survival after transcatheter aortic valve implantation (TAVI) versus surgical aortic valve replacement (SAVR) for severe aortic stenosis (AS) from real‐world clinical practice, we performed a meta‐analysis of observational studies with a propensity‐score analysis and ≥3‐year follow‐up. Methods Databases including MEDLINE and EMBASE were searched through April 2017 using PubMed and OVID....
