[Corrected transposition of the great arteries. Study of 14 cases (author's transl)].

We have studied 14 patients of corrected transposition, 12 with situs solitus and 2 with situs inversus. In all the patients, excepting one, a clinical, radiological and angiocardiographical study was performed. The associated anomalies were determining elements of the clinical situation; the patients with pulmonary obstruction and interventricular communication had cianosis, while the 4 patients with aortic obstruction or anomalies type left Ebstein show cardiac insufficiency. The simple radiological study helped us to determinate the ascendent aorta in the left side of the heart, in 9 cases. It was unusual to see the droped hilium in the right hemitorax. The more significants electrical signs were: The presence of complete A-V block, Q-waves in D2, D3 and aVF, absence of right waves in precordial leads in most of the patients and a negative T wave in a VL. Summarizing, authors believe that in this type of defects selective injection of contrast in both ventricles is the best method to establish the difference between corrected transposition and other cardiopathies with the aorta situated at the left side of the pulmonary artery.
