Abstract Background Rheumatic mitral stenosis constitutes a major cause of acquired heart disease complicating pregnancy in India. In the present study, we have studied the fetal and maternal outcomes of women undergoing balloon mitral valvotomy during pregnancy. Methods and results 49 pregnant ladies were included in this study in whom balloon mitral valvotomy was performed. The mean age of these patients was 25.7 ± 3.1 years. The mean gestational age was 23.5 ± 5.2 weeks (12–36 weeks). The procedure was successful in 48 patients (95.9%). Mean two-dimensional MVA increased from baseline value of 0.93 ± 0.17 cm2 to 1.75 ± 0.27 cm2 ( p value
