[Interruption of the aortic arch and malformative cardiac lesions requiring repair under extracorporeal circulation. Apropos of 3 cases].
Interruption of the aortic arch is practically always associated with intracardiac malformations of variable complexity, at the least, a ventricular septal defect. Surgery is usually performed in two stages: aortic repair and pulmonary artery banding after intravenous prostaglandin administration. The second stage comprises debanding and repair of the intracardiac lesions under cardiopulmonary bypass. However, in some cases, interruption of the aortic arch is associated with intracardiac lesions which necessitate correction under cardiopulmonary bypass from the onset, this was the situation in two of the three cases described by the authors: aorto-pulmonary window, a lesion which can only be corrected under circulatory arrest and deep hypothermia. One of these two children, operated in the neonatal period, did not survive: the other, operated at 6 weeks, had an excellent result. In the third case, the association of tricuspid atresia and a restrictive ventricular septal defect necessitated enlargement of the septal defect and therefore, open heart surgery under circulatory arrest; the results were favourable.
