title: [Atrioventricular canal associated with Fallot's tetralogy. Anatomo-clinical study of 2 cases].
abstract: The Authors are examing two cases of A-V canal associated with T. of Fallot. The most important clinical aspects of this rare cardiopathy result in the following: -- the frequent coexistence with Down dyndrome; -- the ECG and VCG aspects of counterclockwise rotation of the initial vectors of QRS in the frontal plane; -- the simultaneous observation of the typical echocardiographical aspects of both kinds of cardiopathy. The injection of dye into both ventricles allows the precise diagnosis. The post-mortem study in both cases shows the morphology of A-V canal associated with the one of T. of Fallot. From the surgical point of view it is important to take into account the abnormal morphology and extension of VSD. The importance of the part that the conal cushion plays in the morphogenesis of the malformation is discussed.
