title: Coarctation of the aorta in complex congenital heart disease: simultaneous repair via sternotomy.
abstract: Coarctation of the aorta (CoA) is often associated with complex congenital heart disease. Patients with such a combination may not benefit from coarctectomy alone. Eight children who presented with complex malformations of the heart underwent simultaneous repair of CoA and intracardiac surgery via sternotomy. After extensive mobilization of the aortic arch, cardiopulmonary bypass was established. During the cooling phase for deep hypothermic circulatory arrest (six cases), a persistent temperature gradient between the upper and lower half of the body confirmed the significance of CoA. One child was operated upon in deep hypothermia with low flow and one underwent valve repair on cardiopulmonary bypass. Mobilization of the descending aorta enabled CoA resection and end-to-end anastomosis with a running absorbable suture. The average descending aortic cross-clamping time was 15 min. By this time, the patient had been cooled sufficiently for the intracardiac procedure. There were two operative deaths not related to coarctectomy. The remaining children showed no arm-to-leg pressure gradient. Five were discharged from hospital and one patient died late from septicaemia. In our hands, this technique has served to accomplish simultaneous relief of CoA and repair of the intracardiac lesion thus sparing critically ill infants the hazards of repeated procedures.
