A new surgical technique for one-stage repair of interrupted aortic arch with valvular aortic stenosis

Abstract

Clinical Summary A male neonate weighing 3100 g was referred to our hospital with cyanosis and respiratory distress. Two-dimensional echocardiography showed type B IAA, patent ductus arteriosus, subarterial VSD, and valvular aortic stenosis. The aortic valve was bicuspid and the annular diameter measured 3.0 mm. The infundibular septum was deviated posteriorly. Because aortic flow was decreased because of a left-to-right shunt through VSD, a significant pressure gradient across the aortic valve and subaortic portion was not detected by Doppler echocardiogram.
