[Heart valve prosthesis, pregnancy and anticoagulant therapy].
Minerva ginecologica, 1991The 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.

Characterization of a Novel Polymeric Trileaflet Heart Valve Prosthesis
ASME 2009 Summer Bioengineering Conference, Parts A and B, 2009While heart valve prostheses have been used successfully since 1960, 10-year survival rates still range from 37–58% [1]. The underlying problem with bioprostheses is a limited life from structural changes such as calcification and leaflet wear, leading to valve failure [2]. Biological tissue fixation and methods used to mount the tissue to a supporting

Calculation of the stresses in the cusp of a leaflet heart-valve prosthesis
Polymer Mechanics, 1976The stresses occurring in the cusp of a leaflet heart-valve prosthesis, simulated by a quarter of a spherical shell with a semicircular base, have been calculated and analyzed with a view to identifying and strengthening the most vulnerable points of the prothesis. Expressions are obtained for calculating the tensile and shear stress in the cusp of the

A study of the stability of orientation in the CarboMedics bileaflet heart valve prosthesis
European Journal of Cardio-Thoracic Surgery, 1992A total of 25 CarboMedics bileaflet prostheses was studied in the immediate postoperative period and at 1 week, 1 month and 3 months after surgery. No evidence of rotation was found on visual comparison of valve orientation and there were no significant differences between successive studies for the distance between the septum and either the anterior ...

Pregnancy and successful delivery in a patient with triple heart valve prosthesis
International Journal of Gynecology & Obstetrics, 1993AbstractA 42‐year‐old patient had a history of rheumatic fever in childhood. At 37 years of age, she underwent a triple heart valve replacement; thereafter, she was followed with the administration of warfarin and methyldigoxin. Her third pregnancy occurred with the last menstruation on 12 March 1990.

Steady and Pulsatile Flow Studies on a Trileaflet Heart Valve Prosthesis
Scandinavian Journal of Thoracic and Cardiovascular Surgery, 1983The need for better and longer lasting trileaflet valves has led to the design and development of the ABIOMED polymeric trileaflet valve prosthesis. In vitro fluid dynamic studies in the aortic position indicate that overall it has improved leaflet motion characteristics and pressure drop characteristics compared to the Carpentier-Edwards porcine and ...

Experience with the St. Jude medical heart valve prosthesis
1987During the past 25 years, numerous different technical conceptions for the development of a suitable artificial heart valve have been followed, only a few of which led to clinical applicability. Among those prostheses which reached the stage of clinical testing, only a small number have proved to be reliable for a certain space of time.
