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

Clinical performance of decellularized heart valves versus standard tissue conduits: a systematic review and meta-analysis

Journal of Cardiothoracic Surgery, 2020
Background Valve replacement surgery is the definitive management strategy for patients with severe valvular disease. However, valvular conduits currently in clinical use are associated with significant limitations.

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).

Comparative analysis of ovine and human aortic valve tissue for bioprosthetic valve development using relaxation tests and numerical simulation [PDF]

Scientific Reports
As the demand for aortic valve prostheses grows, optimizing their mechanical performance and durability is essential. While mechanical valves offer longevity, their need for lifelong anticoagulation limits their use, making bioprosthetic valves a ...

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.

Models of immunogenicity in preclinical assessment of tissue engineered heart valves.

Acta Biomaterialia, 2021
Tissue engineered heart valves may one day offer an exciting alternative to traditional valve prostheses. Methods of construction vary, from decellularised animal tissue to synthetic hydrogels, but the goal is the same: the creation of a 'living valve ...

Management of Life-Threatening Bleeding in Patients With Mechanical Heart Valves

Cureus, 2021
Valvular heart disease is common in the United States, with a number of patients undergoing valve replacement procedures every year. The two types of valve prostheses include mechanical and bioprosthetic valves.
