Objectives: This study aimed to perform the first meta-analysis of studies comparing transcarotid (TC) and trans-subclavian (TSc) transcatheter aortic valve replacement (TAVR).Background: The safety and feasibility of a TC and a TSc approach for performing TAVR in patients with prohibitive femoral anatomy have been well described. The potential advantage of one approach over the other is yet to be ascertained.Methods: A computerized literature search of key medical databases through September 2020 was performed. Randomized controlled trials (RCTs) and observational studies comparing TC and TSc TAVR with reported 30-day outcomes were considered. The primary endpoint was a composite of all-cause mortality, stroke, life-threatening, and/or major bleeding or major vascular complications. Statistical analysis using random-effects models to report the odds ratio (OR) with 95% confidence interval (CI) was performed.Results: A total of 5 observational studies inclusive of 4164 patients (TC = 1788 and TSc = 2376) met the eligibility criteria. The average age of patients was 81.1 years. There was no difference in the occurrence of the composite endpoint between the groups at 30-days. A statistically insignificant trend towards higher rates of major vascular complications (OR 1.65; 95% CI 0.94-2.89; P = 0.08; I2 = 0%) and the need for permanent pacemaker placement was observed with the TSc approach.Conclusions: This meta-analysis of studies comparing TC and TSc TAVR showed similar 30-day outcomes between the 2 approaches. A notable trend towards higher rates of major vascular complications and the need for permanent pacemaker placement was observed with the TSc approach. [ABSTRACT FROM AUTHOR]
