Warfarin in patients with mechanical heart valves
British medical journal, 2020### What you need to know A 55 year old woman with severe aortic stenosis underwent valve replacement with a mechanical valve. She has been started on warfarin and is maintaining an international normalised ratio (INR) within the target range of 2.0-3.0.

Annual Review of Physiology, 1979
The goal implicit in the research reviewed above is to describe the contractile behavior of heart muscle in terms of crossbridge and filament behavior. It is necessary to elucidate these details in cardiac muscle because of the distinct biochemical differences between skeletal and cardiac myosin.

Nature, 1950
FROM experiments by several investigators it can be assumed that the heart mechanism of most Crustacea differs from the mechanism of the heart of vertebrates. The heart in Crustacea appears to possess a neurogenic automatism, as has been shown by its reactions to drugs and by histological examination.

Mechanical heart valve prostheses
Cardiovascular Pathology, 2003Abstract Mechanical heart value prostheses have been in use since the 1950s. Many prostheses have been used for a while and then discontinued. Today, there are a large number and variety of prostheses in use and an even larger variety that are in place in patients. These may be explanted at any time for a number of reasons.

Mechanical heart valve cavitation
Expert Review of Medical Devices, 2004Cavitation was first directly related to mechanical heart valves in the mid 1980s after a series of valve failures observed with the Edwards-Duromedics valve. The damages observed indicated that cavitation could be responsible. Later, several in vitro studies visualized the bubble formation and collapse of cavitation at mechanical heart valves.

The question of why the myocardium fails to contact normally and ultimately leads to congestive failure, has occupied the attention of both clinicians and basic scientists for decades. Nevertheless, it is only within recent years that improvements in clinical diagnostic techniques and development of more sophisticated physiological and biochemical ...

Propagation Mechanisms in Heart
Annual Review of Physiology, 1979The myocardium is composed of an assembly of short cells, separated at their ends by the intercalated disks (IDs). The fluid in the 10 cleft gap is continuous with the bulk interstitial fluid (ISF), and the width of the gap averages about 200 A.. Regions where the two membranes come into closer proximity are termed the gap junctions.

Innate Mechanisms of Heart Regeneration
Cold Spring Harbor Perspectives in Biology, 2021Heart regeneration is a remarkable process whereby regrowth of damaged cardiac tissue rehabilitates organ anatomy and function. Unfortunately, the human heart is highly resistant to regeneration, which creates a shortage of cardiomyocytes in the wake of ischemic injury, and explains, in part, why coronary artery disease remains a leading cause of death
