Operator experience and technical improvements have improved outcomes especially for patients undergoing TAVR. We sought to determine and compare 1-year outcomes using a contemporary meta-analysis.\n<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Method<\/jats:title>\n                <jats:p>We searched the Medline (MESH), Cochrane and Google scholar databases using keywords \u201cAS\u201d, \u201catrial fibrillation\u201d (AFib) and \u201cstroke\u201d. We performed a meta-analysis to compare TAVR with SAVR populations for post-procedural stroke, all-cause and cardiovascular mortality at 1-year.\n<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>A total of 23 studies met criteria for analysis with total population of 66,857 patients, of which 61,913 had TAVR and 4944 had SAVR. Temporal trends demonstrated overall improvement in outcome for both, TAVR and SAVR groups through the decade. Outcomes, in terms of stroke (3.1% vs. 5%), all-cause (12.4% vs. 10.3%) and cardiovascular mortality (7.2% vs. 6.2%) were similar at 1-year, in TAVR versus SAVR, respectively.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Despite overall gradual improvement in both TAVR and SAVR outcomes over the decade, there is a statistical overlap in confidence intervals for all-cause, cardiovascular mortality and postprocedural stroke at 1-year.
