Current Opinion in Cardiology, 1993
Progress in valve repair and replacement continued over the past year. Aortic valve repair for aortic insufficiency appears promising, and aortic decalcification may still be a useful alternative in certain cases of aortic stenosis. Mitral valve repair, well accepted for myxomatous valves, presents a challenge in ischemic disease.

Patents and Heart Valve Surgery – III: Percutaneous Heart Valves
Recent Patents on Cardiovascular Drug Discovery, 2014Advancements in technology for the treatment of valvularcardiac diseases seek to provide solutions for high risk patients in the form of percutaneous valve insertion for patients with complicated valvular disease not amenable to more traditional options.

Heart valve tissue engineering
Transplant Immunology, 2004Valvular heart disease is a significant cause of morbidity and mortality world-wide. Classical replacement surgery involves the implantation of mechanical valves or biological valves (xeno- or homografts). Tissue engineering of heart valves represents a new experimental concept to improve current modes of therapy in valvular heart surgery.

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.

Transplantability of Heart Valves
Archives of Surgery, 1962The 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 ...

Heart valve bioprostheses: antimineralization
European Journal of Cardio-Thoracic Surgery, 1992Clinical and experimental studies indicate that calcification of bioprosthetic valves depends on host, implant, and biomechanical factors. The earliest mineral deposits in both clinical and experimental bioprosthetic tissue are localize to transplanted connective tissue cells; collagen involvement occurs later. Passive calcium entry occurs unimpeded in

Valvular heart disease, infected valves and prosthetic heart valves
The American Journal of Cardiology, 1990The major causes of systemic embolism from valvular heart disease (mitral, aortic and mitral valve prolapse), prosthetic valves (both mechanical and tissue valves) and infected valves (endocarditis) are reviewed from the standpoint of their incidence and complications.

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.
