The conclusions drawn have been limited by small sample sizes. The use of TAVR for BcAV stenosis remains controversial.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We searched multiple databases from the inception of the databases through September 30, 2016 for studies of TAVR for BcAV stenosis. We included all observational studies with more than one patient and at least 1 month of outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We analyzed 13 observational studies with 758 patients. Meta analyses showed device success rate of 95% [95% confidence interval (CI) 90.2% to 98.5%] and an early safety event in 16.9% [95% CI 12.2% to 22%]. At 30 days, moderate to severe paravalvular leak was seen in 12.2% [95% CI 3.1% to 24.8%] and new pacemaker implantation in 17.9% [95% CI 14.2% to 22%]. All\u2010cause mortality was 3.7% [95% CI 2.1% to 5.6%], which should be viewed in the context of an STS PROM of 5.0%.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>This analysis suggests that TAVR for BcAV is not associated with excess mortality. The incidence of paravalvular leaks and pacemaker implant is increased compared to tricuspid aortic valve cohorts undergoing TAVR, and operators should weigh these potential complications against the clinical benefit provided by TAVR for BcAV patients at high risk for surgical valve replacement.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ccd.27340","type":"journal-article","created":{"date-parts":[[2017,9,30]],"date-time":"2017-09-30T06:32:50Z","timestamp":1506753170000},"page":"975-983","source":"Crossref","is-referenced-by-count":24,"title":["<scp>T<\/scp>ranscatheter aortic valve replacement for stenotic bicuspid aortic valves: <scp>S<\/scp>ystematic review and meta analyses of observational studies"],"prefix":"10.1002","volume":"91","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7129-7663","authenticated-orcid":false,"given":"Gautam","family":"Reddy","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Diseases Mayo Clinic Rochester Minnesota"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhen","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Diseases Mayo Clinic Rochester Minnesota"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rick A.","family":"Nishimura","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Diseases Mayo Clinic Rochester Minnesota"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kevin L.","family":"Greason","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Diseases Mayo Clinic Rochester Minnesota"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sung\u2010Han","family":"Yoon","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Diseases Cedars Sinai Medical Center Los Angeles California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raj R.","family":"Makkar","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Diseases Cedars Sinai Medical Center Los Angeles California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"Jr.","given":"David R.","family":"Holmes","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Diseases Mayo Clinic Rochester Minnesota"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,9,30]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9343(70)80070-5"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.107.740878"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.0000155623.48408.C5"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2014.02.537"},{"key":"e_1_2_9_6_1","doi-asserted-by":"crossref","unstructured":"Joint Task Force on the Management of Valvular Heart Disease of the European Society of Cardiology (ESC); European Association for Cardio\u2010Thoracic Surgery (EACTS); Vahanian A Alfieri O Andreotti F Antunes MJ Bar\u00f3n\u2010Esquivias G Baumgartner H Borger MA Carrel TP De Bonis M Evangelista A Falk V Iung B Lancellotti P Pierard L Price S Sch\u00e4fers HJ Schuler G Stepinska J Swedberg K Takkenberg J Von Oppell UO Windecker S Zamorano JL Zembala M.
