title: Persistent atrio-ventricular canal. Case report of an unusual intermediate form.
abstract: A case is described, which presented the following combination of anomalies: An interatrial and interventricular septal defect, absence of a cleft in the aortic leaflet of the mitral valve and in the septal leaflet of the tricuspid valve. The latter leaflet was underdeveloped and presented several perforations. On the bases of the characteristic electrocardiographic, angiocardiographic and anatomical findings this anomaly was considered to be an intermediate form of a common atrioventricular canal. Total repair was successfully performed utilizing the technique of Rastelli and McGoon.
