Key result
Percutaneous mitral valvuloplasty improved mean mitral pressure gradient from 32 to 8 mmHg and valve area from 0.9 to 2.4 cm2, allowing for normal full-term delivery without complications.
Why the study?
Does percutaneous mitral valvuloplasty improve hemodynamics and allow safe delivery in a pregnant woman with severe rheumatic mitral stenosis?

Does percutaneous mitral valvuloplasty improve hemodynamics and allow safe delivery in a pregnant woman with severe rheumatic mitral stenosis?
Percutaneous mitral valvuloplasty can be safely and effectively performed during mid-term pregnancy in patients with severe rheumatic mitral stenosis.
May support PMV for safe delivery in mid-pregnancy severe rheumatic MS; hypothesis-generating and should not yet change practice.
A 28-year-old woman with severe mitral stenosis underwent percutaneous mitral valvuloplasty at 26 weeks' gestation. Balloon dilation using a double 18-18 mm balloon resulted in improvement in mean mitral pressure gradient (32 to 8 mmHg) and in calculated mitral valve area (0.9 to 2.4 cm2) without complications and any evidence of fetal distress during procedures with an estimated radiation exposure to the fetus of 0.13 rem. This procedure resulted in the disappearance of symptoms of congestive heart failure and allowed for normal full term spontaneous delivery of a 3.51 Kg boy without any complication.

Lee et al. (1992) conducted a case report in Severe rheumatic mitral stenosis (n=1). Percutaneous mitral valvuloplasty was evaluated on Mean mitral pressure gradient and calculated mitral valve area. Percutaneous mitral valvuloplasty improved mean mitral pressure gradient from 32 to 8 mmHg and valve area from 0.9 to 2.4 cm2, allowing for normal full-term delivery without complications.
