Mechanotransduction of autotransplants: remodeling potential of heart valves from autologous pericardial tissue [PDF]

Frontiers in Bioengineering and Biotechnology
Current commercial heart valve prostheses are non-living structures, either derived from artificial materials (mechanical valves) or foreign biological materials (xeno- or homo-graft).

A chronological history of heart valve prostheses to offer perspectives of their limitations [PDF]

Frontiers in Bioengineering and Biotechnology
Prosthetic heart valves (PHV) have been studied for around 70 years. They are the best alternative to save the life of patients with cardiac valve diseases. However, current PHVs may still cause significant disadvantages to patients.

Advancements and Perspectives in the Bioprosthetic Heart Valve: A Comprehensive Review on Biomaterial Processing and Emerging Polymeric Materials [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Heart valve disease contributes to cardiovascular disease–associated death. Bioprosthetic heart valves have emerged as a preferred option for heart valve replacement due to their superior hemodynamic performance and reduced need for lifelong ...

Fluid-structure interaction simulation of prosthetic aortic valves : comparison between immersed boundary and arbitrary Lagrangian-Eulerian techniques for the mesh representation [PDF]

, 2016
In recent years the role of FSI (fluid-structure interaction) simulations in the analysis of the fluid-mechanics of heart valves is becoming more and more important, being able to capture the interaction between the blood and both the surrounding ...

Tissue Engineering Heart Valves – a Review of More than Two Decades into Preclinical and Clinical Testing for Obtaining the Next Generation of Heart Valve Substitutes [PDF]

Romanian Journal of Cardiology, 2021
Well documented shortcomings of current heart valve substitutes – biological and mechanical prostheses make them imperfect choices for patients diagnosed with heart valve disease, in need for a cardiac valve replacement.

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

A Newly Developed Tri-Leaflet Polymeric Heart Valve Prosthesis. [PDF]

, 2015
The potential of polymeric heart valves (PHV) prostheses is to combine the hemodynamic performances of biological valves with the durability of mechanical valves. The aim of this work is to design and develop a new tri-leaflet prosthetic heart valve (HV)

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
