  1. Polymeric Transcatheter Heart Valves

    Coetzee, JohanDivision of General Surgery2019

    Rheumatic heart disease (RHD) is one of the main causes of heart disease in the emerging world. Once the disease has become symptomatic valve repair or replacement is the only treatment currently available. Commercial bioprosthetic valves (surgical and transcatheter) suffer from calcification and …

    Falahatpisheh, Ahmad

    <p>Heart valves play an important role in directing blood flow and preventing back flow in the heart. Design and development of bioprosthetic heart valves has been a major focus of research in the field of cardiovascular engineering as they are a better replacement for natural diseased valves than …

  7. Hybrid Electrospun Transcatheter Aortic Heart Valves for Tissue Engineering Applications

    Taylor, JadeDivision of Biomedical Engineering2022

    Bioprosthetic and mechanical heart valves are suboptimal due to both calcific degeneration and the need for lifelong anticoagulation treatment. Tissue engineering (TE) has the potential to overcome these and other shortcomings by providing viable valves capable of growth, remodelling, and repair. …

    Vossler, John DavidWake Forest University2015

    The long term efficacy of heart valve bioprostheses is limited by progressive degeneration characterized by immune mediated inflammation and calcification. To avoid this degeneration, decellularized heart valves with functionalized surfaces capable of rapid in vivo endothelialization have been …

    Forléo, Márcio Henrique, author, Dasi, Lakshmi Prasad, advisor, James, Susan, committee member, Orton, Christopher, committee member, Dinenno, Frank, committee memberColorado State University. Libraries2014

    Implantation of a bileaflet mechanical heart valve (BMHV) continues to be associated with risk of thromboembolic complications despite anti-coagulation therapy. Mechanical heart valves have been the gold standard in valve heart replacement since the 1950s with BMHVs currently still being the valve …
