Heart valves

Medical Device Technologies, 2021
Publisher Summary A prosthetic heart valve is a medical device that replaces a diseased native valve and that enables blood flow in the cardiac chambers to be regulated. A mechanical valve consists of an occluder, an occluder retention mechanism, and a sewing cuff. A typical tissue valve consists of porcine or bovine tissue, a stent, and a sewing cuff.

Heart valves cross-linked with erythrocyte membrane drug-loaded nanoparticles as a biomimetic strategy for anti-coagulation, anti-inflammation, anti-calcification, and endothelialization.

ACS Applied Materials and Interfaces, 2020
In recent years, valvular heart disease has become a serious disease threatening human life and is a major cause of death worldwide. However, the glutaraldehyde (GLU)-treated biological heart valves (BHVs) fail to meet all requirements of clinical ...

Biological heart valves

Biomedizinische Technik/Biomedical Engineering, 2013
Cardiac valvular pathologies are often caused by rheumatic fever in young adults, atherosclerosis in elderly patients, or by congenital malformation of the heart in children, in effect affecting almost all population ages. Almost 300,000 heart valve operations are performed worldwide annually.

Stolen Heart Valves?

Scottish Medical Journal, 1987
A patient having had both aortic and mitral valves replaced complained of triggering shop security alarms, attributing the problem to the prosthetic valves. It was demonstrated that the valves were not the cause of the problem and the source identified.

Artificial Heart Valves [PDF]

Annual Review of Medicine, 1990
This overview of heart valve prostheses is based on a current review of clinical reports and focuses on the major complications that characterize long-term valve performance: thromboembolism, thrombosis, anti-coagulant-related bleeding, and structural failure.
