Obstetric history after mechanical cardiac valve replacement.

Results 45.7% had successful pregnancy outcome. 40% cases had missed abortion. Five patients chose to have Medical Termination of Pregnancy (MTP) with tubal ligation. The majority of subjects (76.4%) delivered within 5 years of valve replacement. Despite counselling about embryopathy all except one patient continued to take oral anticoagulants. There was no maternal mortality. Morbidity in the ...

Rapid-Deployment Aortic Valve Replacement after Previous Mechanical Valve Implantation

Recent studies report a reproducible reduction of myocardial ischemic and cardiopulmonary bypass times along with excellent hemodynamics and low rates of paravalvular leakage for rapid-deployment valves. A 68-year-old female patient with aortic stenosis and a mechanical mitral valve which was implanted in 2006 received rapid-deployment aortic valve replacement. The procedure could be performed ...

Lung mechanics after cardiac valve replacement.

Fourteen patients undergoing single aortic or mitral valve replacement had measurements made of lung volumes, static pressure-volume (P-V) relationships, and conductance-pressure relationships during deflation before operation and again between one and two years later. At follow-up, total lung capacity (TLC), functional residual capacity (FRC), residual volume (RV), and static tidal compliance ...

pregnancy outcome after mechanical mitral valve replacement: a prospective study

background: pregnant patients with mechanical heart valves require anticoagulation. the risk of bleeding and embryopathy associated with oral anticoagulants must be weighed against the risk of valve thrombosis. methods: in this prospective study, undertaken between 1999 and 2009, 53 pregnancies (47 women with mechanical mitral valves; 29.8 ± 4.8 years old) were studied. patients were divided in...

Cardiac crossroads: deciding between mechanical or bioprosthetic heart valve replacement

Nearly 15 million people in the United States suffer from either aortic or mitral valvular disease. For patients with severe and symptomatic valvular heart disease, valve replacement surgery improves morbidity and mortality outcomes. In 2009, 90,000 valve replacement surgeries were performed in the United States. This review evaluates the advantages and disadvantages of mechanical and bioprosth...
