Mitral valve replacement with mechanical or bioprosthetic valve
Multimedia Manual of Cardio-Thoracic Surgery, 2005A presentation on the technique of mitral valve replacement is shown: exposure and excision of the diseased mitral valve is demonstrated along with the use of sub-annular and supra-annular interrupted suture techniques for securing biological and mechanical mitral prostheses. A brief overview of the literature is presented.

Tissue Valve Degeneration and Mechanical Valve Failure
Current Treatment Options in Cardiovascular Medicine, 2019The management of valvular heart disease has been dramatically influenced by recent evolutions in biomedical technology and surgical practice. With an aging population worldwide and accompanying increase in the prevalence of surgical valve disease, an understanding of prosthetic valve behavior and durability is essential for proper patient selection ...

Tricuspid Valve Replacement: Bioprosthetic or Mechanical Valve?
Asian Cardiovascular and Thoracic Annals, 2004Significant morbidity and mortality is associated with tricuspid valve replacement, and controversy still exists as to the ideal prosthesis in this position. This study aimed to identify the risk factors for low cardiac output and mortality, and whether bioprosthetic or mechanical valves perform better in the tricuspid position.

Patents and Heart Valve Surgery - I: Mechanical Valves
Recent Patents on Cardiovascular Drug Discovery, 2013Valvular heart disease, inherited or acquired, affects more than 5 million Americans yearly. Whereas medical treatment is beneficial in the initial stages of valvular heart disease, surgical correction provides symptomatic relief and long-term survival benefits.

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.

Fluid Mechanics of the Mitral Valve
Nature, 1969THE exploitation of trapped vortices and flow deceleration by the aortic valve to ensure maximum efficiency and to make possible laminar flow1,2 suggests a similar mechanism for the atrio-ventricular valves. These are the inlet valves to the two ventricles, the mitral valve on the left side and the tricuspid valve on the right.

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.

Mechanism of Closure of the Aortic Valve
Nature, 1968THE human aortic valve consists of three cusps made of relatively inelastic, muscle-free material about 0.15 mm thick. It opens and shuts about once a second, and withstands a pressure difference of 100 mm of mercury when closed. It usually functions for 70 yr without failure, and works so efficiently that very little blood is regurgitated at each ...
