A Deep Learning Framework for Design and Analysis of Surgical Bioprosthetic Heart Valves. [PDF]
Sci Rep, 2019 Bioprosthetic heart valves (BHVs) are commonly used as heart valve replacements but they are prone to fatigue failure; estimating their remaining life directly from medical images is difficult.

Imaging of Bioprosthetic Valve Dysfunction after Transcatheter Aortic Valve Implantation
Diagnostics, 2023 Transcatheter aortic valve implantation (TAVI) has become the standard of care in elderly high-risk patients with symptomatic severe aortic stenosis. Recently, TAVI has been increasingly performed in younger-, intermediate- and lower-risk populations ...

Quadruple Bioprosthetic Valve Replacement in a Patient With Severe Carcinoid Heart Disease
JACC: Case Reports, 2020 Carcinoid heart disease typically affects the tricuspid and pulmonary valves, causing severe regurgitation and/or stenosis. Valve surgery has been shown to reduce right heart failure and improve long-term prognosis in these patients.

The susceptibility of bioprosthetic heart valve leaflets to oxidation [PDF]
Biomaterials, 2014 The clinical use of bioprosthetic heart valves (BHV) is limited due to device failure caused by structural degeneration of BHV leaflets. In this study we investigated the hypothesis that oxidative stress contributes to this process. Fifteen clinical BHV that had been removed for device failure were analyzed for oxidized amino acids using mass ...
