We searched for predictors of long-term outcome including the surgeon as risk factor.<\/jats:p><jats:p>\n          Methods\u2003We selected all aortic valve reimplantations performed in our department between December 1999 and January 2017 and obtained a complete follow-up. The main indications were combined aortic aneurysm plus aortic valve regurgitation (AR), 69% and aortic dissections (15%). In 14%, valves were bicuspid. Cusp repair was performed in 27% of patients. One-third received additional procedures (coronary artery bypass grafting, mitral, or arch surgery). We performed multivariable analyses for independent risk factors of short- and long-term outcomes, including \u201csurgeon\u201d as variable. Twelve different surgeons operated on 193 patients. We created three groups: surgeons A and B with 84 and 64 procedures, respectively, and surgeon C (10 surgeons for 45 patients).<\/jats:p><jats:p>\n          Results\u2003Cardiopulmonary bypass and clamp times were 176\u2009\u00b1\u200945 and 130\u2009\u00b1\u200924\u2009minutes, respectively. In-hospital mortality was 2%. Postoperatively, 5% had mild and 0.5% had moderate AR. Kaplan\u2013Meier's survival estimates, freedom from reoperation, and freedom from severe AR at 12 years were 97\u2009\u00b1\u20091, 93\u2009\u00b1\u20092, and 91\u2009\u00b1\u20093%, respectively. Age and chronic obstructive pulmonary disease appeared as risk factors for perioperative complications by univariate analysis. Age, coronary artery disease, and duration of cardiopulmonary bypass, but not surgeon, presented as risk factors by multivariable analysis.<\/jats:p><jats:p>\n          Conclusion\u2003The results suggest that if a David procedure is performed successfully, long-term durability may be excellent. They also suggest that good and durable results are possible even with limited experience of the operating surgeon.<\/jats:p>","DOI":"10.1055\/s-0038-1675594","type":"journal-article","created":{"date-parts":[[2018,11,29]],"date-time":"2018-11-29T00:37:33Z","timestamp":1543451853000},"page":"567-574","source":"Crossref","is-referenced-by-count":2,"title":["Predictors of Outcome for Aortic Valve Reimplantation Including the Surgeon\u2014A Single-Center Experience"],"prefix":"10.1055","volume":"68","author":[{"given":"Sophie","family":"Tkebuchava","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, University Hospital Jena, Friedrich Schiller University Jena, Jena, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Raphael","family":"Tasar","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, University Hospital Jena, Friedrich Schiller University Jena, Jena, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Lehmann","sequence":"additional","affiliation":[{"name":"Institute of Medical Statistics, Information Sciences and Documentation, University Hospital Jena, Friedrich Schiller University Jena, Jena, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gloria","family":"Faerber","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, University Hospital Jena, Friedrich Schiller University Jena, Jena, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mahmoud","family":"Diab","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, University Hospital Jena, Friedrich Schiller University Jena, Jena, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin","family":"Breuer","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, University Hospital Jena, Friedrich Schiller University Jena, Jena, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ulrich","family":"Franke","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Robert-Bosch-Hospital, Stuttgart, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hristo","family":"Kirov","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, University Hospital Jena, Friedrich Schiller University Jena, Jena, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jan","family":"Gummert","sequence":"additional","affiliation":[{"name":"Clinic for Thoracic and Cardiovascular Surgery, Heart Center North Rhine-Westphalia, Bad Oeynhausen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Artur","family":"Lichtenberg","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Medical Faculty, Heinrich Heine University, Duesseldorf, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thorsten","family":"Wahlers","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, Heart Center of the University of Cologne, Cologne, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Torsten","family":"Doenst","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, University Hospital Jena, Friedrich Schiller University Jena, Jena, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2018,11,28]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"S1","DOI":"10.1016\/j.athoracsur.2013.01.083","article-title":"Aortic valve and ascending aorta guidelines for management and quality measures","volume":"95","author":"L G Svensson","year":"2013","journal-title":"Ann Thorac Surg"},{"issue":"02","key":"ref2","doi-asserted-by":"crossref","first-page":"347","DOI":"10.1016\/j.jtcvs.2006.03.053","article-title":"Long-term results of aortic valve-sparing operations for aortic root aneurysm","volume":"132","author":"T E David","year":"2006","journal-title":"J Thorac Cardiovasc Surg"},{"issue":"04","key":"ref3","doi-asserted-by":"crossref","first-page":"617","DOI":"10.1016\/S0022-5223(19)34942-6","article-title":"An aortic valve-sparing operation for patients with aortic incompetence and aneurysm of the ascending aorta","volume":"103","author":"T E David","year":"1992","journal-title":"J Thorac Cardiovasc Surg"},{"issue":"04","key":"ref4","doi-asserted-by":"crossref","first-page":"952","DOI":"10.1016\/S0735-1097(87)80254-1","article-title":"Evaluation of aortic insufficiency by Doppler color flow mapping","volume":"9","author":"G J Perry","year":"1987","journal-title":"J Am Coll Cardiol"},{"issue":"01","key":"ref5","doi-asserted-by":"crossref","first-page":"40","DOI":"10.1097\/00005650-199401000-00004","article-title":"The MOS 36-item Short-Form Health Survey (SF-36): III.
