[A rationale for the surgical treatment of congenital heart diseases with different variants of disorders of the atrioventricular connections (criss-cross heart)].

The authors studied the angiocardiographic picture in different variants of criss-cross atrioventricular connections in 24 patients. This is the greatest number of cases described in the world literature. The tactics of surgical treatment in various types of a criss-cross heart is substantiated on the grounds of analysis of hemodynamics and concomitant congenital heart diseases. Operation on a patient with a criss-cross heart should consist in correction of the concomitant anomalies and, if necessary, it should be supplemented by intracardiac correction of the blood flow (Mustard's operation). Fontana's operation is the only method of surgical treatment of patients with a complicated complex of anomalies.
