Objective: In this study, we presented the clinical characteristics of the patients we performed arterial switch operation between 2018-2020 in our clinic and our experience in this regard. Methods: Arterial switch operations were performed in 29 patients in total with 13 simple and 16 complex transposition of the great arteries (TGA) diagnoses in two years. Ten patients in the simple TGA group were operated within the first 14 days after birth, and the other three patients were operated at 14-60 days of age. Eleven patients from the complex TGA group were operated within the first 14 days, and five patients within 14-60 days. Preoperative, operative process and postoperative short and long term results were evaluated in both groups. Our study was approved by the decision of the Ethics Committee dated 26.04.2021 and numbered 12.
