Paediatric nanofibrous bioprosthetic heart valve

IET Nanobiotechnology, 2017
The search for an optimal aortic valve implant with durability, calcification resistance, excellent haemodynamic parameters and ability to withstand mechanical loading is yet to be met. Thus, there has been struggled to fabricate bio‐prosthetics heart valve using bioengineering.

Valve in valve and valve in ring transcatheter aortic valve implantation [PDF]

Българска кардиология, 2022
In recent years the trend towards surgical bioprosthetic valve implantation, especially among young patients, has increased in order to avoid anticoagulant therapy. The patient’s age remains one of the leading risk factors for valve dysfunction.

Degenerative processes in bioprosthetic mitral valves in juvenile pigs

Journal of Cardiothoracic Surgery, 2011
Background Glutaraldehyde-treated bioprosthetic heart valves are commonly used for replacement of diseased heart valves. However, calcification and wear limit their durability, and the development of new and improved bioprosthetic valve designs is needed

Bioprosthetic valve thrombosis in carcinoid heart disease

Annals of Cardiac Anaesthesia, 2019
Tricuspid regurgitation in carcinoid syndrome leads to significant morbidity and mortality that may warrant a tricuspid valve replacement. However, for patients with high serotonin levels and known hypercoagulable risks, the optimum timing for surgery and postoperative anticoagulation approaches remain unclear.

Design and Fabrication of Three-Dimensional Scaffolds for Tissue Engineering of Human Heart Valves [PDF]

, 2008
We developed a new fabrication technique for 3-dimensional scaffolds for tissue engineering of human heart valve tissue. A human aortic homograft was scanned with an X-ray computer tomograph.
