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 ...

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.

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.

Heart Valve Disease

Primary Care: Clinics in Office Practice, 2013
Heart valve disease is often characterized by a prolonged asymptomatic period that lasts for years and presents primary care physicians with an opportunity to detect disease before irreversible heart failure or other cardiac complications develop. Acute valvular disease can masquerade as respiratory illness or present with nonspecific systemic symptoms,

Prosthetic Heart Valve

Emergency Medicine Clinics of North America, 1994
There are tens of thousands of patients with prosthetic heart valves implanted today, and although complications are infrequent, this may not hold true as patients live longer with prosthetic valves and as more and newer valves are implanted. A familiarity with the management of such patients will aid the emergency physician in the evaluation of this ...

Transplantability of Heart Valves

Archives of Surgery, 1962
The majority of unresolved problems in the present era of heart surgery are biologic rather than technical. The advances made in total body perfusion, the improvement in the protection of the myocardium in artificially induced cardiac arrest, etc., have made it possible to deal quite successfully with several types of congenital and acquired heart ...

Artificial Heart Valves

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.

Prosthetic Heart Valves

New England Journal of Medicine, 1996
Since the 1950s more than 80 models of prosthetic heart valves have been developed and used. More than 60,000 valve replacements are performed annually in the United States. Prosthetic heart valves may be mechanical or bioprosthetic. Mechanical valves, which are composed primarily of metal or carbon alloys, are classified according to their structure ...
