In congenital aortic stenosis, most of patients have obtained satisfactory results with valvotomy, but some required reoperation with valve replacement even during childhood. In supracristed VSD associated with aortic regurgitation, late recurrence of regurgitation was found in some, but 70% of the patients showed free of diastolic murmur after 10 years. In tetralogy of Fallot, definitive repair of pulmonary valve was performed in last 5 years with composite patch with patient's own pericardium to reduce postoperative pulmonary regurgitation. Recently, pericardium is treated with glutaraldehyde on the operating table to prevent late shrinkage.
As external conduit, homograft aorta, which had been utilized previously, showed good late results comparable to xenograft in terms of free from reoperation. Xenograft has been frequently utilized without significant late obstruction so far. In atrioventricular canal, endocardial cushion prosthesis technique has been utilized satisfactory with recent modification of the wings made by glutaraldehyde treated patient's own pericardium as well as in tetralogy.
