ABSTRACT
Study population involved 21 pts with complex congenital heart disease after corrective surgery using homografts between the years 1986 and 1992. Diagnoses included double outlet right ventricle, tetralogy of Fallot, transposition of great arteries, truncus arteriosus, pulmonary atresia with VSD, corrected transposition with pulmonary stenosis, and absent pulmonary valve. Pts age at surgery ranged from 18 days--to 15 yrs mean, 6.7 yrs. Time interval between surgery and diagnostic procedures was 8 days--6 yrs (mean 11 months). All pts were studied by Echo/Doppler. 2 pts by TEE and 3 pts by MRI. 6 pts had cardiac catheterisation. Distal (5) or proximal (1) stenosis was present in 6 cases. The severity and the type of stenosis was correctly identified by noninvasive technique compared to invasive findings. Homograft valve regurgitation was mild (4) or moderate (3). In two pts severe insufficiency was associated to homograft endocarditis. Postoperative residual shunts were found in 8 pts. Homograft stenosis can correctly be diagnosed using Echo/Doppler technique. Distal stenosis was more frequent than proximal. Homograft tends to become insufficient, but severe incompetence did not occur except in endocarditis.
