Abstract

Background: Aortic coarctation (CoA) is a congenital heart disease (CHD) marked by discrete or diffuse narrowing in the descending aorta at the juxta-ductal region.1 It represents 5-8% of all CHD. Surgical repair is an established technique, and it is used when catheter intervention is not suitable.
The aim of the study: To analyse the impact of present anatomical characteristics and surgical performance (end-to-end and extended end-to-end anastomosis) on early outcomes, in children not suitable for percutaneous catheter intervention.
Methods: This is a prospective study performed on 60 patients who underwent CoA repair from January 2022 to December 2024. The patients who had end-to-end repair (EEA) were group A, and the other who had extended end-to-end repair (EEEA) were group B. 
Results: In group A, 56.7% of the patients were females. The mean pre-operative PPG across CoArc was 64.9±6.2 mmHg. The mean cross-clamp time was 16.0±1.4 minutes. The mean post-operative PG was 16.5±2.1 mmHg. While in group B, 46.7% of the patients were females. The mean CoA length was 4.07±2.08 mm, and the mean CoA diameter was 2.89±0.56 mm. The mean cross-clamp time was 28.9±3.5 minutes. The mean post-operative PG was 4.2±2.8 mmHg. There were statistically significant differences regarding cross-clamp time and mean postoperative PG (P value <0.001 & <0.001, respectively).
Conclusion: Our study reported that surgical repair of AoC in children is an alternative method to catheter intervention. It had good results, whatever the method of anastomosis was used.
