Abstract:
An incidental finding of right coronary artery compression between the dilated aortic root and the sternum was detected on follow-up cardiac catheterization after Fontan completion for tricuspid atresia with transposition of the great arteries. Although this 31-year-old man had no subjective symptoms, an exercise stress test and perfusion scan revealed ischemic changes in the inferior region. Valve-sparing aortic root replacement using the reimplantation technique proved to be an effective approach for this condition. The possibility of coronary artery compression associated with aortic root dilatation should be considered in adult patients with congenital heart disease.
