Deformities of Pulmonary and Aortic Annulus 42 Years after Repair of Tetralogy of Fallot

抄録

We report an extremely rare case of deformity of the pulmonary sinus of Valsalva with pulmonary valvular stenosis 42 years after a pulmonary annular-sparing operation for tetralogy of Fallot. Aortic regurgitation with deformity of the sinus is also noted. At the previous operation, the right ventricular outflow tract was augmented by a prosthetic subvalvular patch. Through the years, the pulmonary valve and sinus were distorted because the patch was pulled over toward the right ventricle.
