Bioprostheses were implanted in 53 patients with a mean age of 74 years, and mechanical prostheses were used in 83 with a mean age of 64 years; there were 47 women and 89 men. Quality of life was evaluated using the Short Form 36-Item Health Survey questionnaire. Physical function scores were significantly better in patients with a mechanical prosthesis. Mental health indices were identical in both groups. Younger patients with mechanical valves and older patients with biological valves had significantly better item scores. In all age groups, men tended to have better scores than women, but a significant difference was noted only in the physical functioning index. The quality of life in patients with mechanical and biological valves was similar at 2 years postoperatively.<\/jats:p>","DOI":"10.1177\/0218492309102522","type":"journal-article","created":{"date-parts":[[2013,5,6]],"date-time":"2013-05-06T09:37:22Z","timestamp":1367833042000},"page":"35-38","source":"Crossref","is-referenced-by-count":13,"title":["Quality of Life after Mechanical vs. Biological Aortic Valve Replacement"],"prefix":"10.1177","volume":"17","author":[{"given":"Anas","family":"Aboud","sequence":"first","affiliation":[{"name":"Department of Cardiothoracic Surgery, Herz- und Diabeteszentrum NRW, Bad Oeynhausen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin","family":"Breuer","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, Friedrich Schiller University, Jena, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Torsten","family":"Bossert","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, Friedrich Schiller University, Jena, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jan F","family":"Gummert","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, Herz- und Diabeteszentrum NRW, Bad Oeynhausen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2009,2,1]]},"reference":[{"key":"bibr1-0218492309102522","doi-asserted-by":"publisher","DOI":"10.1016\/0003-4975(95)00936-1"},{"key":"bibr2-0218492309102522","first-page":"339","volume":"4","author":"Myken P","year":"1995","journal-title":"J Heart Valve Dis"},{"key":"bibr3-0218492309102522","first-page":"81","volume":"98","author":"Perchinsky M","year":"1998","journal-title":"Circulation"},{"key":"bibr4-0218492309102522","doi-asserted-by":"publisher","DOI":"10.1378\/chest.119.1_suppl.220S"},{"key":"bibr5-0218492309102522","doi-asserted-by":"publisher","DOI":"10.1016\/0003-4975(96)00629-7"},{"key":"bibr6-0218492309102522","unstructured":"Society of Thoracic Surgeons National Database Committee.
