Continuous cerebral and myocardial perfusion during aortic arch repair in neonates and infants.
To minimize myocardial ischemia, we repaired aortic arch obstruction with ventricular septal defect, using two different techniques of cerebral and myocardial perfusion. Seventy-one infants, ages 3 to 137 days, underwent primary repair of coarctation of the aorta (n = 49)/interruption of the aortic arch (n = 22) with ventricular septal defect. In 65 patients, an end-to-end arch anastomosis was performed with cerebral and myocardial perfusion through the innominate or the ascending arterial cannula (non-working beating heart: NWBH). In the remaining 6 patients, an arterial cannula was placed into the innominate artery. With partial cardiopulmonary bypass, the innominate artery was snared proximal to the cannulation site and the ascending aorta was cross-clamped. An extended arch anastomosis was carried out with cerebral perfusion and a working beating heart (WBH). Ten patients (15%) undergoing aortic arch repair with the NWBH technique required cardioplegic arrest to complete a proximal anastomosis, whereas in all 6 repairs with the WBH technique, the extended anastomoses were completed without myocardial ischemia. One hospital death and late death occurred, with an overall survival of 98%. End-to-end arch reconstruction is feasible without myocardial ischemia, using the NWBH technique in patients without hypoplastic arch and using the WBH technique in patients with hypoplastic arch.
