Alloplastic materials for heart-valve prostheses [PDF]

Medical & Biological Engineering & Computing, 1980
Alloplastic materials have found wide application in heart-valve prostheses, in spite of the need for permanent anticoagulant treatment. Though biological valves exhibit excellent thromboresistance, they fail in long-term application because of a disintegration of the tissue structure.

dynamics of mechanical heart valve prostheses [PDF]

WIT Transactions on Biomedicine and Health, 1970
A numerical code for analyzing the dynamic behaviour of heart valve prostheses is presented. The study is conducted with the valve in a simplified cardiovascular system, represented schematically by a circuit with a pump, the valve under test, a rugged elastic tube and a capacity.
