Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • New York Heart Association Functional class (NYHA Fc) ≥ 2 dyspnea which was sustained till one year after the previous mitral valve surgery (repair or replacement)
  • TR Vmax ≥ 3.5m/s by echocardiography
  • Normal left ventricle ejection fraction (EF ≥ 50%)
  • Pulmonary vascular resistance ≥ 3 Wood Unit or diastolic pressure gradient ≥ 7mmHg by cardiac catheterization

You may not qualify if:

  • Liver cirrhosis
  • Chronic renal failure with serum creatinine ≥ 1.7mg/dL
  • Lung disease (ex. chronic obstructive pulmonary disease, Asthma)
  • Thyroid dysfunction
