Аннотация
A 6-year-old boy was diagnosed with aggravation of diffuse supravalvular aortic stenosis (SVAS). The pressure gradient between the sinus of Valsalva and ascending aorta was 48 mmHg. The diameter of the sino-tubular junction was 7 mm and the ascending aorta was hypoplastic. We performed Myers operation because 3 sinus reconstructions had resulted in superior hemodynamics and reductions in both mortality rate and need for reoperation. We avoided using autologous pericardium because of the possibility of shrinkage and aneurysm. We could easily perform patch enlargement of the ascending aorta by selective cerebral perfusion. The postoperative course was excellent and there was no SVAS or aortic regurgitation (AR). A catheterization showed the pressure gradient was 5 mmHg with trivial AR upon follow-up at 1 year.
