Antithrombotic Therapy in Patients with Prosthetic Heart Valves [PDF]
Libyan Journal of Medicine, 2009 Patients with mechanical valve prostheses require a lifelong anticoagulant treatment. The combined use of Warfarin and low-dose aspirin appears to reduce the risk of valve thrombosis and systemic embolism at a low risk of bleeding.

On the setting up of numerical modeling of heart valve prostheses
Сибирский научный медицинский журналThe aim of the study was to compare scenarios of numerical modeling of the operation of a heart valve bioprosthesis, identifying their advantages and limitations. Material and methods. Numerical modeling was conducted in the Abaqus/ CAE (Dassault Systèmes, France) engineering analysis environment, simulating two cycles of the valve apparatus’s ...

Biodegradable Poly-ε-Caprolactone Scaffolds with ECFCs and iMSCs for Tissue-Engineered Heart Valves
International Journal of Molecular Sciences, 2022 Clinically used heart valve prostheses, despite their progress, are still associated with limitations. Biodegradable poly-ε-caprolactone (PCL) nanofiber scaffolds, as a matrix, were seeded with human endothelial colony-forming cells (ECFCs) and human ...

A New Nanocomposite Copolymer Based On Functionalised Graphene Oxide for Development of Heart Valves
Scientific Reports, 2020 Polymeric heart valves seem to be an attractive alternative to mechanical and biological prostheses as they are more durable, due to the superior properties of novel polymers, and have the biocompatibility and hemodynamics comparable to tissue ...

Developing the Tissue Engineered Heart Valve – a Descriptive Hemodynamic and Ultrasound in Vitro Characterization Study of Heart Valves in a Bioreactor [PDF]
Romanian Journal of Cardiology, 2021 The inherent limitations of current heart valve substitutes create the premise for the Tissue Engineered Heart Valve (TEHV), considered the perfect substitute. We aimed to compare in vitro hemodynamic performances of our TEHV, the conventional prosthetic

Fluid dynamic characterization of a polymeric heart valve prototype (Poli-Valve) tested under continuous and pulsatile flow conditions. [PDF]
, 2015 PURPOSE: Only mechanical and biological heart valve prostheses are currently commercially available. The former show longer durability but require anticoagulant therapy; the latter display better fluid dynamic behavior but do not have adequate durability.
