tissue heart valves
infective endocarditis is a severe condition which occurs on native as well as on artificial valves. both mechanical prosthetic devices and tissue heart valves are affected. the incidence of endocarditis, in western countries, ranges from 1.5 to 6.2 cases per 100,000 people per annum. the cumulative rate of prosthetic valve endocarditis is 1.5 to 3.0% at one year following valve replacement and 3 to 6% at five years, the risk being the greatest during the first six months after valve replacement.

valve replacement









































valve replacement surgery is the replacement of one or more of the heart valves with either an artificial heart valve or a bioprosthesis (homograft from human tissue or xenograft e.g. from pig). it is an alternative to valve repair.









































there are four procedures









































bullet::::- aortic valve replacement









































bullet::::- mitral valve replacement









































bullet::::- tricuspid valve replacement









































bullet::::- pulmonary valve replacement









































current aortic valve replacement approaches include closed heart surgery, very invasive cardiac surgery (vics) and very invasive, scapulae-based aortic valve replacement.
