Fifteen infants less than 12 months of age with complete atrioventricular
septal defects underwent repair of the defect between January, 1981, and
December, 1984. The average age at operation was 8 1/2 months and the
average weight was 5.7 kg. Eight of 15 (53%) infants had preoperative mild
to moderate mitral insufficiency. Pulmonary artery hypertension was present
in all infants and 13 of 15 infants had a pulmonary arterial resistance
greater than 4 units (mean 8.8 units). Operative indication was based on
pulmonary artery hypertension, congestive heart failure, and failure to
thrive. Ventricular distention was utilized during operative repair to
assess location of valve incision, level of attachment of valves to the
patch, and cleft approximation. It was also used to check the competency of
the mitral repair once complete. The average circulatory arrest time was
55.7 minutes. There were no operative deaths. There were two late deaths.
We conclude that ventricular distention is the key to the operation, and
operative repair is safe in infants with atrioventricular septal defects.
