Abstract
Transpositions of the great arteries are a heterogeneous group of complicated congenital heart diseases that vary in terms of the management, subsequent complications, and long-term prognosis. In congenitally corrected transposition without surgery and uncorrected transposition after arterial switch, there is the right ventricle in the systemic position, and in adulthood there predominate problems with heart failure and/or systemic tricuspid valve regurgitation, with arrhythmias also being frequent.
On the contrary, uncorrected transposition after arterial switch in childhood has a very favourable course in adulthood.
