RESULTS: Cardiac anatomy was single ventricle (1V) in 34 subjects and
2 ventricles (2V) in 65. Medical comorbidities were present in 21% and
genetic syndromes in 19%. Most subjects (75%) had DD in $1 area at
$1 assessments. Subjects with 1V anatomy had equivalent outcomes
to those with 2V. Cognitive and language scores declined in subjects
with genetic syndromes but were stable and within the average range
for subjects with 1V and 2V. Motor scores improved for subjects with
1V and 2V but remained low for those with genetic syndromes. In
addition to age, need for supplemental tube feeding, longer cardiopulmonary
bypass time, and shorter time since last hospitalization
were significant predictors of developmental outcomes
