Entanglement of a Cardiac Catheter on a Heart-Valve Prosthesis

New England Journal of Medicine, 1966
THIS 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 ...

A mitral valve prosthesis and a study of thrombosis on heart valves in dogs

Journal of Surgical Research, 1962
Summary o 1. A prosthesis for the atrioventricular heart valves has been designed which tends to imitate the natural mitral valve. The valve is cylindric in shape and is made of smooth polyurethane. The fixation ring is flexible, with Dacron mesh and polyurethane sponge provided for fixation. The sutures are shielded from the blood stream.

[Heart valve prosthesis and pregnancy].

Akusherstvo i ginekologiia, 1979
Sixteen 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.

HEART VALVE REPLACEMENT BY PORCINE AORTIC VALVE (HANCOCK PROSTHESIS)

Medical Journal of Australia, 1977
Glutaraldehyde preservation of heterograft valves has increased their durability. Sixty-nine Hancock prostheses have been implanted, 30 in the mitral position and 39 in the aortic position. Anticoagulants have not been administered. There has been one important thromboembolic complication and periprosthetic mitral incompetence has occurred in three ...

Heart valve prosthesis

2012
A heart valve prosthesis comprising: a support structure comprising a framework deformable between an expanded state and a compressed state and vice versa; and a flow-control structure, supported by the support structure, for permitting blood flow in a first direction, and for restricting blood flow in a direction opposite to the first direction.

Anticoagulant therapy and heart valve prosthesis

1994
The success of current heart valve surgery is largely due to the development of valve prostheses to replace damaged native valves. Since 1960, when Starr performed the first successful mitral valve replacement with a caged ball prostheses [2], some 60 different prosthesis have been developed in 30 years. Most prostheses fall within two broad categories:

The porcine heart valve prosthesis.

Medical instrumentation, 1977
The 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.

[Heart valve prosthesis in congenital heart defects].

Kardiologiia, 1977
The experience of 68 cases of prosthetic valve replacement for congenital heart diseases is presented. The majority of the cases were 57 patients with the Ebstein anomaly and tetralogy of Fallot. In the patients with the Ebstein anomaly the tricuspid valve was replaced, in those with the tetralogy of Fallot--a plastic enlargement of the pulmonary ...
