Abstract

Background/Aim: A transposition complex with an interrupted aortic arch (IAA) is rare and surgically challenging because of its anatomical diversity and complexity. Herein, we aimed to present our 20-year experience with one-stage arterial switch surgery associated with IAA repair. Methods: From January 2000 to April 2017, 11 patients were diagnosed with transposition complex and IAA and underwent one-stage repair at our center. These patients were retrospectively reviewed. Two patients had transposition of the great arteries, while the others had double outlet right ventricles, of whom eight had subpulmonary ventricular septal defects (Taussig-Bing anomalies), and one had a non-committed ventricular septal defect. In terms of the IAA, three patients underwent repair by extended end-to-end anastomosis, and one 16-mm prosthetic vascular graft was replaced in an elder patient. The remaining patients underwent autologous pericardial patch enlargement. All the variables were summarized and reported with descriptive statistics. Results: Three early deaths occurred in this study. The median follow-up time was approximately 5 years (range: 3 – 14 years). No late deaths were reported. Only one patient required percutaneous re-intervention for recurrent coarctation. Moderate aortic regurgitation was observed in three patients. However, there was no requirement for aortic valvuloplasty or valve replacement. One patient had more than moderate tricuspid regurgitation. The other survivors are presently healthy. Conclusions: Although one-stage repair for transposition complex and IAA still has non-negligible mortality even in older children, the late outcomes of survivors are acceptable. Owing to the high rate of valve regurgitation, closer follow-up is necessary for these patients.
