<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <sec id="jocs12093-sec-0001" sec-type="section"> <title>Background</title> <p>The purpose of this study was to evaluate the clinical outcomes and risk of tricuspid valve replacements and to compare bioprosthetic versus mechanical valves.</p> </sec> <sec id="jocs12093-sec-0002" sec-type="section"> <title>Methods</title> <p>Between 1991 and 2009, 104 consecutive patients (71 women; mean age, 57 ± 10.8 years) with tricuspid valvular disease underwent mechanical TVR (mechanical group; n = 59) or bioprosthetic TVR (bioprosthesis group; n = 45).

Ten‐year actuarial survival after mechanical and bioprosthetic TVR was 83.9 ± 7.6% and 61.4 ± 9.1%, respectively (p = 0.004). However, there was also no significant difference in terms of adjusted analysis by propensity score (p = 0.084).
