Rheumatic mitral disease

Fish-mouth configuration of Mitral valve

  • Fish-mouth configuration of Mitral valve
  • Commissural fusion
  • chordal thickening and fusion, and leaflet thickening
  • Fish-mouth configuration -calcification that develop in patients with rheumatic mitral stenosis result in narrowing of the mitral orifice, classically with a fish-mouth configuration
  • Commissural fusion results in restricted diastolic excursion of the tips of the leaflets, with relatively preserved mobility of the belly of the leaflet, particularly in early or milder forms of the disease
  • Anterior leaflet doming
  • Posterior leaflet is shorter and tends to become immobilized early in the rheumatic process
