Structural valve failure of TTK Chitra heart valve prosthesis

Indian Journal of Thoracic and Cardiovascular Surgery, 2023
Mechanical prosthetic valve dysfunction can be structural or non-structural. Structural valve dysfunction includes disc dislodgement, disc fracture, and strut fracture. These events in an implanted valve are rare but could pose a risk to life. TTK Chitra heart valve prosthesis (CHVP), an Indian-made single tilting disc valve, has been implanted since ...

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 and pregnancy].

Archives des maladies du coeur et des vaisseaux, 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 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.

Developments in mechanical heart valve prosthesis

Sadhana, 2003
Artificial heart valves are engineered devices used for replacing diseased or damaged natural valves of the heart. Most commonly used for replacement are mechanical heart valves and biological valves. This paper briefly outlines the evolution, designs employed, materials being used,. and important factors that affect the performance of mechanical heart

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:

[Heart valve prosthesis, pregnancy and anticoagulant therapy].

Minerva ginecologica, 1991
The reproductive possibilities of cardiopathic patients with cardiac valvular prostheses have greatly improved in the past forty years. The correct management of this risk pregnancies remains a problem, however, especially as regards the chronic anticoagulant treatment to which these patients are subjected.

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, anticoagulants and pregnancy].

Polski tygodnik lekarski (Warsaw, Poland : 1960), 1991
Patients with artificial valve prostheses require lifelong anticoagulation treatment. The risk of thrombotic complications increases greatly in pregnancy. Anticoagulant treatment in pregnant women with artificial heart valve prostheses in one of the most controversial problems in medical practice as anticoagulants which are beneficial and safe for the ...
