Immediate and long-term outcomes of balloon mitral valvotomy in pregnancy

Objectives: To study the immediate maternal and fetal outcomes and long term maternal outcomes in pregnant women undergoing balloon mitral valvotomy. Methods: We retrospectively analyzed balloon mitral valvotomy during pregnancy performed between January 2008 and July 2018. Results: BMV was carried out in 97 pregnant women with mean age of 26.1 ± 4.5 years, at mean gestational age of 23.1 ± 4.6 weeks. The procedure was successful in 95 patients (97.9%). There was one maternal death post procedure due to intra-uterine death and disseminated intravascular coagulation. Adverse immediate fetal outcome was seen in 2 cases with one intra-uterine fetal demise and one preterm labour. Mitral valve area increased from mean of 0.82 ± 0.12 cm to 1.66 ± 0.14 cm (p
