- Obstetric History
In patients who have undergone mechanical prosthetic heart valve replacement, pregnancy is associated with the risks of warfarin embryopathy. A significant proportion of our patient undergoing mechanical mitral cardiac valve replacement were females of child bearing age.
To study the obstetric history in patients after mechanical cardiac valve replacement.
Retrospective analysis of 35 subjects who conceived after cardiac valve replacement with mechanical valves and presented with 45 pregnancies was carried out. Ten patients had multiple pregnancies (2 each). 10 patients had documentary evidence of termination of pregnancy elsewhere outside the institute. Thus we document 35 pregnancies in 25 cases.

Significant proportion of patients having valve replacement in our centre are females. Post-surgery their obstetric history is complicated by poor awareness about oral anticoagulation and its effect on pregnancy this results in delay in seeking appropriate obstetric care. In pregnancy there is an increased fetal wastage in patients taking oral anticoagulants though women with artificial valves can tolerate the hemodynamic load of pregnancy well. A successful pregnancy outcome in women with surgically corrected valve pathology involves preconception evaluation, counseling, close supervision during her pregnancy and labor.
