Tetralogy of Fallot with atrioventricular canal. An angiographic study
PH Nath, B Soto, RM Bini, LM Bargeron Jr and AD Pacifico
Tetralogy of Fallot associated with atrioventricular (AV) canal is a
well-recognized cardiac malformation; its surgical repair carries a high
mortality, which is related partly to the complexity of the defect and
partly to incomplete diagnosis. Hence an accurate preoperative diagnosis is
essential. This communication describes the angiographic features observed
in 17 patients with tetralogy of Fallot and AV canal with emphasis on the
morphology of the right AV valve as seen during the right ventriculogram. A
complete anatomic diagnosis can be consistently made from right and left
ventriculograms performed in axial projections.
