Differential diagnosis


  • Echocardiogram
  • ECG: may show atrial fibrillation and p-mitrale (broad, bifid P waves)
  • Chest x-ray
  • Blood cultures, if considering infective endocarditis


Anticoagulation, diuretics and digoxin can be used to medically improve morbidity and mortality in cases involving atrial fibrillation and heart failure. In severe cases, especially in the presence of atrial fibrillation, mitral valvotomy or valve replacement can be offered.
