Echocardiography of Complete atrioventricular canal

CAVC is a complex cardiac malformation characterised by a variable deficiency of the atrioventricular area (crux cordis) in the developing heart. The malformation involves the atrial, ventricular and atrioventricular septa and both atrioventricular valves.

Anatomic classification of CAVC:

  • Type A - the superior bridging leaflet is almost completely adherent to the left ventricle and is firmly attached on the ventricular septum by multiple chordal insertions
  • Type B - the superior bridging leaflet is attached over the ventricular septum by an anomalous papillary muscle of the right ventricle
  • Type C - the superior bridging leaflet is not attached to the ventricular septum (free-floating leaflet)
