Comparison of transcatheter aortic valve implantation with other approaches to treat aortic valve stenosis: A systematic review and meta-analysis

Background Transcatheter aortic valve replacement (TAVI) is an alternative treatment for patients with symptomatic severe aortic stenosis ineligible for surgical aortic valve replacement (SAVR) or at increased perioperative risk. Due to continually emerging evidence, we performed a systematic review and meta-analysis comparing benefits and harms of TAVI, SAVR, medical therapy, and balloon aortic valvuloplasty.
