Heart valve bioprostheses: antimineralization

European Journal of Cardio-Thoracic Surgery, 1992
Clinical 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, 1990
The 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, 2003
Abstract 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.

Partial Heart Transplant in a Neonate With Irreparable Truncal Valve Dysfunction.

Journal of the American Medical Association (JAMA)
Importance The treatment of neonates with irreparable heart valve dysfunction remains an unsolved problem because there are no heart valve implants that grow.

Acute Heart Valve Emergencies

Cardiology Clinics
Within the cardiac intensive care unit, prompt recognition of severe acute valvular lesions is essential because hemodynamic collapse can occur rapidly, especially when cardiac chambers have not had time for compensatory remodeling. Within this context, optimal medical management, considerations for temporary mechanical circulatory support and decisive
