Successful Percutaneous Mitral Valve Balloon Valvuloplasty during Third Trimester

Abstract

ABSTRACT Rheumatic mitral stenosis is the most common acquired valvular lesion in pregnant women. The overall mortality is 1%, but can go up to 5% in those patients with New York Heart Association class III and IV symptoms. Percutaneous mitral balloon valvuloplasty (PMBV) is the procedure of choice in the treatment of rheumatic mitral stenosis. The PMBV is usually done in the first or second trimester, but in the third trimester, PMBV is a less common procedure. A 24-year-old gravida 2 para 1 living 1 with 35 weeks of gestation with previous lower segment cesarean section (LSCS) presented with breathlessness and swelling of lower limbs. Evaluation revealed rheumatic mitral stenosis of moderate severity with moderate mitral regurgitation with cardiac failure. Hence, PMBV was done, which resulted in increase of mitral valve area from 0.6 to 1.7 cm2. She had marked symptomatic improvement, and cesarean section was done at 36 weeks 5 days for previous LSCS with preterm premature rupture of membranes. The postoperative period was uneventful. Our report reinforces the fact that third trimester PMBV is safe and effective during pregnancy with no untoward effect on the fetus.
