[Characteristics of the radical correction of Fallot's tetralogy in anomalous distribution of the coronary arteries].

The variants of distribution of the coronary arteries were studied on 41 specimens of the heart with Fallot's tetralogy. The typical topography of the coronary arteries in this cardiac defect is characterized by counterclockwise rotation of the coronary sinuses, dominant system of the right coronary artery with a large infundibular branch, and right type of heart blood supply. There were 6 variants of anomalies of the coronary arteries. The most characteristic of Fallot's tetralogy were: a single coronary artery, origin of the large infundibular artery by an independent orifice, and anomalous origin of the anterior interventricular branch from the right coronary artery. The peculiarities of radical correction of the tetralogy in atypical distribution of the coronary arteries were discussed on the basis of analysis of 27 operations conducted with the use of non-traditional methods of correction.
