Angiocardiography in the diagnosis of interventricular septum defects in a double displacement of great vessels from the right ventricle]

The paper is devoted to analysis of the results of angiocardiographic investigation of 237 patients with a double deflection of great vessels (DDGV) from the right ventricle (RV) (the patients ranged in age from 3 months to 23.5 years) to study the potentialities of the method in the diagnosis of a defect position of the interventricular septum (DIVS). Angiographic investigation permitted a sufficiently accurate determination of a DIVS position in DDGV from the RV. Of paramount importance for determining a DIVS position is the establishment of the interrelationships of the latter with the infundibular septum and the openings of major arteries. For diagnosis of a DIVS position one should necessarily use left and right ventriculography both in standard and axial projections.
