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 ...

OBJECTIVES Sutureless aortic valve prostheses are gaining popularity due to the substantial reduction in cross-clamp time. In this study, we report our observations on the cusp-fluttering phenomenon of the Perceval bioprosthesis (LivaNova, London, UK ...

A mitral valve prosthesis and a study of thrombosis on heart valves in dogs
Journal of Surgical Research, 1962Summary 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.

Fiber heart valve prosthesis: Early in vitro fatigue results.
Journal of Biomedical Materials Research. Part B - Applied biomaterials, 2016Transcatheter aortic valve replacement has become today a largely considered alternative technique to surgical valve replacement in patients with high risk for open chest surgery.

A mechanical analysis of the closed Hancock heart valve prosthesis
Journal of Biomechanics, 1988In 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, 1975This 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.

In Vivo Evaluation of the Lillehei-Kaster Heart Valve Prosthesis
The Annals of Thoracic Surgery, 1976In vivo evaluation of the Lillehei-Kaster heart valve prosthesis was performed in 28 patients; 22 had undergone aortic valve replacement and 6 had had mitral valve replacement. Mean pressure gradients ranged from 6 to 53 mm Hg in aortic prostheses; valve area varied from 0.83 to 2.9 cm2. The maximum opening angle of 80 degrees was never reached in this
