Entanglement of a Cardiac Catheter on a Heart-Valve Prosthesis
New England Journal of Medicine, 1966THIS report describes an unusual and potentially lethal complication of catheterization of the aortic root that occurred during study of a patient who had previously undergone replacement of the aortic valve with a ball-valve prosthesis (Magovern valve).1 Case Report M.B., a 23-year-old woman, was admitted to the Hospital of the University of ...

[Heart valve prosthesis and pregnancy].
Archives des maladies du coeur et des vaisseaux, 1979Sixteen pregnancies were followed up in 13 patients with prosthetic heart valves: 8 pregnancies went to term under oral anticoagulation, 4 under heparin and 4 without anticoagulation. 9 healthy normal children were delivered; there were 2 still births and 5 abortions.

The porcine heart valve prosthesis.
Medical instrumentation, 1977The development of the prosthetic heart valve has led to the evolution of cardiac intensive care units, a better understanding of cardiac function and biocompatible materials, and new surgical procedures. Initial efforts with formaldehyde-fixed valves did not have long-term success.
