[Correction of transposition of great vessels with and without associated congenital defects. Description of two clinical cases].

We describe two cases of corrected transposition of great vessel (L Transposition). The first case was diagnosed in a man of 70 years old and was not associated with other congenital defects. The second case regards a young man of 16 years old and congenital cardiopathy was associated with interventricular defect and left Ebstein disease. We discuss the different evolution of L Transposition according to the presence or not of other congenital defects and we analyse right ventricle behaviour when it is submitted systemic pressure. In the literature only 26 cases of L Transposition were described in patients over 40 years old. The first case represents a rarity and it shows how in the absence of associated congenital defects, the right ventricle is able to adapt to systemic pressure.
