Percutaneous Mitral Valvuloplasty (PMV) offers a safe and effective treatment for pregnant women with severe mitral stenosis. This intervention improved valve function and allowed for uncomplicated pregnancies and deliveries.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Obstetrics

Background:

  • Severe mitral stenosis poses significant risks during pregnancy.
  • Medical management is often insufficient for symptomatic patients.

Observation:

  • Three pregnant women with symptomatic severe mitral stenosis (NYHA Class III/IV) underwent Percutaneous Mitral Valvuloplasty (PMV).
  • Patients presented with reduced mitral valve area, elevated Wilkins scores, and severe pulmonary hypertension.

Findings:

  • PMV significantly increased mitral valve area and decreased transmitral gradients and pulmonary artery pressure.
  • Hemodynamic improvements were sustained, with no modification in mitral insufficiency.
  • All patients experienced successful pregnancies, delivering healthy infants, and remained in NYHA Class I post-procedure.

Implications:

  • PMV is a safe and valuable therapeutic option for pregnant patients with severe mitral stenosis refractory to medical treatment.
  • This procedure can improve maternal cardiac function and lead to favorable pregnancy outcomes.
