The New York Department of Health has cleared Stony Brook University Medical Center in cases involving four families whose children had been treated in the now closed pediatric cardiac surgery program. In 2006, weeks after the department closed the medical center's pediatric cardiac surgery program because it lacked a full-time surgeon, four families filed complaints with the Health Department. They had similar stories, saying their infants, born with heart defects, were treated for stomach problems instead of having cardiac surgery.
