Key result
Percutaneous balloon mitral valvotomy nearly triples mitral valve area in severe stenosis during pregnancy.
Why the study?
Pregnant women with severe rheumatic mitral stenosis face life-threatening complications due to circulatory changes in normal gestation, requiring effective treatment options.

Does percutaneous balloon mitral valvotomy improve hemodynamics and clinical outcomes in pregnant women with severe mitral stenosis?
Percutaneous balloon mitral valvotomy is a safe and effective, potentially life-saving intervention for pregnant women with severe rheumatic mitral stenosis, leading to significant hemodynamic improvement and healthy fetal outcomes.
Farhat et al. (1992) conducted a case report in Severe rheumatic mitral stenosis in pregnancy (n=8). Percutaneous balloon mitral valvotomy (PMV) was evaluated on Hemodynamic improvement (mitral valve area, cardiac index, left atrium pressure, mitral valve gradient) and pregnancy outcomes. Percutaneous balloon mitral valvotomy in pregnant women with severe mitral stenosis increased mean mitral valve area from 0.83 to 2.4 cm2, with all 8 patients delivering healthy full-term babies.
