Comparative Outcomes of Transcatheter Versus Surgical Aortic Valve Replacement in Elderly Patients With Severe Symptomatic Aortic Stenosis: A Systematic Review.

Objectives: Aortic stenosis is the most common valvular heart disease globally; while transcatheter aortic valve replacement (TAVR) has proven to be a competitive alternative to surgical aortic valve replacement (SAVR) and revolutionized treatment, its safety and efficacy has yet to be comprehensively assessed against SAVR for certain subsets of aortic stenosis patients; therefore, this study aims to systematically analyze all the available clinical evidence from randomized clinical trials on TAVR versus SAVR among intermediate and low-risk patients with severe symptomatic aortic stenosis.

Methodology: We performed a systematic review of the randomized controlled trials (RCT), studies comparing TAVR and SAVR in low- and intermediate-risk patients were identified by a comprehensive search of the major databases. Mortality, stroke, length of stay, and other perioperative outcomes were assessed.
