A unique concept of right ventricular outflow tract reconstruction is
presented. Applications of this concept, employing a glutaraldehyde-
preserved heterograft mitral valve leaflet mounted directly to the right
ventricle, was studied in six immature goat models. Interval evaluation of
these models demonstrated no significant outflow tract obstruction or
aneurysm. Only one animal had significant pulmonary outflow regurgitation
angiographically at the time of sacrifice. All heterograft valve leaflets
showed a degree of calcification and/or retraction directly related to the
time interval between implant and sacrifice. Encouraging early results were
obtained with this method of pulmonary outflow tract reconstruction in a
2,400 gram neonate with type I truncus arteriosus.
