Introduction: Rheumatic mitral valve stenosis is most commonlesion and important contributor of mortality in pregnancy. Percutaneousballoon mitral valvuloplasty (BMV) is the intervention ofchoice during pregnancy. Given the procedural complexities and neonatal outcomes after BMV.Methods: During January 2002 to January 2015, eighty-four BMVinterventions during pregnancy were observed. Data on pregnancyand neonatal outcome was evaluated.Results: Mean maternal age of all patients was 25.21 7.66 yearswith maximum number of women in 18–25 years (67.86%) agegroup. Primigravida (36.90%) and second gravida (42.86%) werecommon.Mean gestational age at which BMV performed was 22.43 5.70weeks with majority of interventions during second trimester(84.52%). Significant increase in mitral valve area was observed afterBMV (baseline: 0.92 0.2 cm2; post-BMV: 2.06 0.3 cm2 p < 0.0001).One-third (56/84) pregnancies had full-term birth (≥37 weeks ofgestation), twenty-four (28.57.%) had preterm delivery, threepatients hadmedical termination of pregnancy and one was maceratedstill birth. Birth weight of majority of newborn babies (76/81,93.82%) was 2.5 kg and above with only five (6.17%) babies weighingbelow 2.5 kg. APGAR scores (mean SD) at 1 minute, 5 minute and10 minute were 5.98 0.68, 6.98 0.72 and 8.23 0.45.Discussion and conclusion: BMV during second trimester of pregnancyis feasible and safe. A good success rate was observed in ourexperience. No adverse outcomes were observed for pregnancyand in neonates. With experienced hands, BMV is the choice ofintervention for severe mitral stenosis in pregnancy.
