Angiocardiographic diagnosis of ventricular septal defect localization in double outlet right ventricle.

Children with double outlet right ventricle, aged 3 months to 23.5 years, were examined to assess the possibility of angiocardiographic diagnosis of defect localization. It was found angiocardiography allows satisfactory localization of the defect in question. To be able localize the defect, it is critical to determine the interaction between the defect and the conus septum, and the origin of large arteries. To establish the diagnosis of ventricular septal defect, right and left ventriculography in standard and axial projections must be performed.
