Two-Stage Repair of Truncus Arteriosus Associated With Interrupted Aortic Arch in Critically Ill Patients

Abstract

This report describes 2 newborns with truncus arteriosus associated with an interrupted aortic arch who underwent a 2-stage repair due to poor preoperative condition. A repair of the interrupted aortic arch and ventricular-to-pulmonary artery conduit with a 6-mm Gore-Tex tube was performed as a first stage. Closure of a ventricular septal defect and placement of a right ventricular-to-pulmonary artery homograft conduit were performed electively at 8 months of age.

Repair of common arterial trunk: palliation and delayed correction as a viable alternative strategy in selected patients

“…those with complex anatomy, associated severe cardiac anomalies, postnatal cardiac failure) with immediate palliation and delayed correction (DC) to improve outcomes. The feasibility and the favourable outcomes associated with this approach were reported previously, especially in cases of associated IAA and preoperative low cardiac output [ 8 , 10 ]. Our goal was to compare both strategies (PC and DC) in terms of safety, survival and prognosis.…”

“…Patients with associated cardiac anomalies and a critical preoperative haemodynamic state often require early surgical repair in the neonatal period, which is associated with higher risk. Moreover, truncal valve dysfunction or the presence of IAA is also associated with increasing mortality and complication rates [ 7 , 8 ]. Therefore, precise timing, management of associated cardiac lesions and an extremely poor preoperative condition remain controversial topics [ 9 ].…”
