Balloon mitral valvuloplasty during pregnancy.
OBJECTIVE
Balloon mitral valvuloplasty (BMV) has been performed safely during pregnancy with good results. Reports are few on long-term effects of BMV on childhood development.


METHODS
BMV was performed in 40 pregnant women (age 23.4+/-4.8 years) with severe mitral stenosis at 24.2+/-4.6 weeks of gestation.


RESULTS
Mitral valve area increased from 0.82+/-0.34 to 1.9+/-0.4 cm(2) (P<0.001). One patient had pericardial tamponade. Mean fluoroscopy time was 5.5+/-3.8 min. There was no maternal death, no abortion, no intrauterine growth restriction and one stillbirth. All 39 babies were normal at birth. One baby died at 7 months due to pneumonia. On follow up for 36+/-15 months, all 38 babies maintained normal growth and development without any thyroid disease or malignancy.


CONCLUSIONS
During pregnancy BMV is feasible, safe and effective. Maternal and fetal outcomes are excellent. Growth and milestone of development are not affected.
