The upside-down stentless aortic bioprosthesis to tricuspid valve replacement.

Between March 2008 and January 2009, a stentless tricuspid valve replacement (STVR) was performed in three patients with tricuspid valve endocarditis who were resistant to medical therapy. Intraoperative and follow-up echocardiograms revealed good prosthetic function without stenosis or regurgitation. This technique could be considered an additional surgical option to stented biological valves or homograft implantations in very high risk populations.
