Long-term results of complete correction with homograft reconstruction in pulmonary outflow tract atresia.

The long-termfollow-up over a period of2 to 5years of thefirst 7 survivors of complete correction with homograft reconstruction in pulmonary outflow atresia and extreme Fallot has been studied. Symptomatically, the patients have remained excellent with return to normal of the chest x-rays and electrocardiograms. Investigation has shown continued good function of the homograft aortic valve in the pulmonary position without evidence ofprogressive pulmonary stenosis or regurgitation. Calcification in the aortic wall is common and occurs quickly but does not interfere with the function of the valve.
