Bioprosthesis
• Tissue valves have been used for 25 to 30 years
• Central blood flow
• Low Profile for easy fitting in aortic, mitral & tricuspid
• Continuous coumadin anticoagulation not needed
Causes of Prosthetic Valve Malfunction
• Mechanical Valves are thrombogenic & requires long-term anticoagulation
• Thrombosis causes restriction of the disk movement• Stenosis & regurgitation will occur• Infection• Wearing out• Leaks• Jamming• Sticking• Biprosthetic Degeneration
