Angiocardiography after total correction of tetralogy of Fallot using large homograft arteries

Postoperative angiocardiographic findings were examined in eight patients whose pulmonary artery was reconstructed using an aortic or pulmonary homograft with valve. Apparent dilatation of the outflow tract of the right ventricle was seen in three patients. Only four showed valve mobility, with function judged almost normal in two of them. Calcification in a valve was not seen. The pulmonary trunk showed three directional patters, and stenosis was clearly observed in two cases. calcification of the pulmonary trunk was seen in only one case. The most difficult problem in the reconstruction of the pulmonary artery is the high incidence of pulmonary stenosis.
