Application of successive principles of repair to correct supravalvular aortic stenosis.
The diffuse form of supravalvular aortic stenosis may extend in the takeoff of the coronary and arch arteries. Relief of the supravalvular stenosis requires a harmonious enlargement of the sinotubular junction to maintain aortic valve competence. The technique we used in a 9-year-old boy involved patch enlargement of all affected structures. Deep hypothermic circulatory arrest and retrograde cerebral perfusion was used during repair of the aortic arch and arch arteries.
