Tricuspid valve leaflets (anatomy)

Last reviewed dd mmm yyyy. Last edited dd mmm yyyy

Authoring team

There are three tricuspid valve leaflets or cusps, so giving rise to the name of the valve:

  • septal
  • anterior
  • posterior

Points of note:

  • during diastole, they project into the ventricle and are widely separated from each other
  • each has a central, collagenous lamina fibrosa that is continuous with the fibrous annulus of the valve
  • the lamina fibrosa is surrounded by endocardium
  • the endocardium is continuous at the edges of the valve on the ventricular side with the chordae tendineae
  • individual leaflets are separated by their respective valve commissures, either anteroseptal, posteroseptal or anteroposterior; the commissures can be incomplete leading to fusion of valve leaflets
  • the surface of each leaflet is irregular at its edge due to the presence of numerous 'clefts' - most chordae tendinae insert into this roughened zone from the ventricular side of the valve
