title: [Axial angiography in tetralogy of Fallot].
abstract: We studied 15 patients with the diagnosis of tetralogy of Fallot by means of conventional and axial angiocardiography. Axial studies were performed in the four chamber view (vertical and horizontal X-ray beams) and in the sitting-up view (vertical X-ray beam). With the right ventriculogram we analyzed the anatomic characteristics of this chamber, infundibular stenosis and the pulmonary branches. Left ventriculograms were performed in order to rule out other less common associated defects. In the sitting-up view we analyzed the characteristics of the right ventricular infundibulum and the pulmonary valve, artery and branches. None of our patients underwent aortography or coronary artery angiography. We conclude that utilization of axial angiocardiography is useful in tetralogy of Fallot because it permits a better appreciation of the anatomy of this malformation, the presence or absence of stenosis of the pulmonary branches and other less frequent associated defects. Aortography or coronary artery angiography must be performed in children in which the anatomy of the coronary arteries cannot be determined by either left or right ventriculograms.
