[The heart conduction system in corrected transposition of the great vessels].
Authors collected 110 cases of transposition of great arteries between 1972 and 1989. Nine transpositions were corrected and the conduction system was studied on histological serial sections in 6 of them. Two cases of corrected transposition without septal or any other defect were described in detail, one in situs solitus, another in situs inversus. According to the literature, an anterior conduction system often tends to develop in situs solitus, and posterior conduction system in situs inversus. Two presented cases as well as other cases in situs ambiguous quoted in authors' and other papers showed that an arrangement of conduction system in corrected transposition does not depend on general visceral situs but on mutual position of atrial and ventricular septa instead.
