Atrioventricular septal defect


Types of atrioventricular septal defect accordingly with the Anderson classification:
  • Separate atrioventricular orifices, shunting at the atrial level: ostium primum defect, three leaflet left atrioventricular valve (socalled mitral valve with cleft anterior leaflet)

  • Separate atrioventricular orifices, shunting at the atrial and ventricular levels: ostium primum defect, space between superior and inferior bridging leaflets of the left atrioventricular valve, inlet ventricular septal defect partially or almost completely closed by fibrous tissue of the atrioventricular valve.

  • Common atrioventricular orifice, shunting at atrial and ventricular levels: ostium primum defect, common atrioventricular valve, unrestrictive inlet ventricular septal defect (Fig. 3.5.1)
