[Corrected transposition of the great vessels. A clinical review of 21 cases (author's transl)].

Clinical and instrumental features of 21 cases of congenitally corrected transposition of the great vessels are reviewed. We confirm the rarity of the isolated form of the disease and its frequent association with ventricular septal defect and pulmonary stenosis. Electrocardiographically, the inversion of the first vectors is represented more frequently by the absence of the q wave on the left precordial leads than by the presence of the q wave on the right precordial leads; a very frequent electrocardiographic feature is a positive T wave on the right precordial leads. The angiographic image of the two ventricles in the lateral projection where they appear as crossing each other in their upper part were described. We confirm the poor results of the surgical treatment of the disease and the non-benign prognosis, because of the other associated cardiac anomalies.
