  • Title: Early failure secondary to noncoronary leaflet prolapse in a stentless aortic bioprosthesis.
    Author: Cherian S, Müller H, Kalangos A, Cikirikcioglu M.
    Journal: Tex Heart Inst J; 2012; 39(5):676-9. PubMed ID: 23109766.
    Abstract:
    Structural degeneration is an important long-term disadvantage of biologic prostheses. However, early failure of these prostheses is uncommon and is usually caused by rapid calcification. We report the successful management of a rare case of early failure of a stentless aortic bioprosthesis (within 4 months of implantation). The patient presented with severe noncalcific aortic regurgitation secondary to prolapse of the noncoronary leaflet. In consideration of the acute nature of failure in this new-generation bioprosthesis and its unclear cause, we believe that this report, albeit of a single case, warrants some attention.
