[Importance and potentials of angiocardiographic study in the diagnosis of congenital heart defects].

Contemporary requirements to angiocardiographic examination in congenital heart diseases are discussed. It is shown that patients with high pulmonary hypertension should be examined by means of left ventriculography and aortography which permit the diagnosis of intraventricular septal defect combined with patent ductus arteriosus, common arterial trunk and open atrioventricular canal. Auxiliary methods of examination in such a commonly encountered anomaly as Fallot's tetralogy and atresia of the pulmonary artery are described, which make it possible to judge the condition of the pulmonary artery. The necessity is demonstrated for performing a two- and multiserial examination in complete and corrected transposition of the major vessels, dual origin of the aorta and pulmonary artery from the right ventricle, and in cases with a solitary ventricle. The role of angiocardiography in appraising the volume of cardiac cavities in patients with congenital heart diseases is noted.
