INR variability and outcomes in patients with mechanical heart valve prosthesis.

Thrombosis Research, 2015
The quality of treatment with warfarin is mainly assessed by the time in therapeutic range (TTR) in patients with mechanical heart valve prosthesis (MHV). Our aim was to evaluate if International Normalized Ratio (INR) variability predicted a combined endpoint of thromboembolism, major bleeding and death better than TTR.We included 394 patients at one ...

Clinical outcomes of bileaflet St. Jude Medical and tilting disc TTK Chitra mechanical heart valve prosthesis: A comparative study

Journal of cardiac surgery, 2022
Comparative data on the clinical outcomes of TTK Chitra mechanical heart valve prosthesis (CHVP), an indigenously developed low‐cost tilting disc valve and commonly used bileaflet valve, the St. Jude medical (SJM) prosthesis are sparse.

HEART VALVE REPLACEMENT BY PORCINE AORTIC VALVE (HANCOCK PROSTHESIS) [PDF]

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 ...

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

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.

Transcatheter heart valve explant with infective endocarditis-associated prosthesis failure and outcomes: the EXPLANT-TAVR international registry.

European Heart Journal
BACKGROUND AND AIMS Surgical explantation of transcatheter heart valves (THVs) is rapidly increasing, but there are limited data on patients with THV-associated infective endocarditis (IE).

A mechanical analysis of the closed Hancock heart valve prosthesis

Journal of Biomechanics, 1988
In order to obtain mechanical specifications for the design of an artificial leaflet valve prosthesis, a geometrically non-linear numerical model is developed of a closed Hancock leaflet valve prosthesis. In this model, the fibre reinforcement of the leaflet and the viscoelastic properties of frame and leaflets are incorporated.

Cardiovascular management of pregnant women with a heart valve prosthesis

The American Journal of Cardiology, 1975
This study of 14 pregnancies in 11 patients with a Starr-Edwards valve prosthesis (nine mitral, two aortic) shows that cardiac functional capacity deteriorated to class III (New York Heart Association criteria) in only 1 woman. The deterioration occurred during the third trimester and the patient's condition improved with medical therapy.
