Bioinspired polymeric heart valves: A combined in vitro and in silico approachCentral MessagePerspective

JTCVS Open, 2023
Background: Polymeric heart valves (PHVs) may address the limitations of mechanical and tissue valves in the treatment of valvular heart disease. In this study, a bioinspired valve was designed, assessed in silico, and validated by an in vitro model to ...

Bioprosthetic Heart Valves: Upgrading a 50-Year Old Technology

Frontiers in Cardiovascular Medicine, 2019
Prosthetic heart valves have been commonly used to address the increasing prevalence of valvular heart disease. The ideal prosthetic heart valve substitute should closely mimic the characteristics of a normal native heart valve.

HEART VALVE SURGERY

The Journal of Thoracic and Cardiovascular Surgery, 1965
SUMMARY This paper summarizes the experience in the treatment of a series of 1,370 cases of open-heart surgery. Of these, 964 valvular lesions and the associated pathologic lesion are analyzed. Details of correction and immediate and late results in the treatment of the following groups of lesions were studied: 74 cases of congenital aortic stenosis ...

Evaluation of pliable bioresorbable, elastomeric aortic valve prostheses in sheep during 12 months post implantation

Communications Biology, 2023
Pliable microfibrous, bioresorbable elastomeric heart valve prostheses are investigated in search of sustainable heart valve replacement. These cell-free implants recruit cells and trigger tissue formation on the valves in situ. Our aim is to investigate
