Atrial switch procedure for disease transposition of the great arteries come late at e hospital

Background: Disease transposition of the great arteries is usually screened antenatally and operated arterial switch in the period before 2 weeks of age because without surgical intervention, 90% of children with dying before 6 months of age. However, there are still a small number of patients presenting late who are not suitable for arterial switch operation. Senning or Mustard procedures are the solutions to this situation. Methods: We report two late cases of disease transposition of the great arteries that were diagnosed and operated on at the Pediatric Cardiovascular Surgery Department, Heart Center, E Hospital. Through these two cases, we discuss methods of diagnosis, treatment, and early results and review the medical literature on this disease. Results: Two patients with late diagnosis: type D transposition of the great arteries were operated on by Senning and Mustard methods with good early results, improved clinical status, and no cyanosis. Postoperative ultrasonography did not detect narrowing of the blood tunnel. The electrocardiogram did not detect arrhythmias. Conclusion: Senning or Mustard procedures give good results, are the solution for patients with late detection disease transposition of the great arteries and no longer indicated for arterial switch operation.
