Edwin had the customary blue lips and fingertips of many HTC's open-heart surgery candidates; but he had less energy than most. He stayed curled in his mom's arms most of the day, periodically getting down on the floor to play with his toy cars or to thumb through a book. It wouldn't be long, though, until even this slight stimulation would tire him and again he'd climb onto his mother's lap. Dr. Balzer, his cardiologist at St. Louis Children's Hospital, soon discovered that Edwin's heart defect was more complex than originally believed. Dr. Sanjiv Gandhi performed the first surgery to place a shunt in his pulmonary artery. Edwin, who left with much more energy than he came with, will return in one year for his second life-saving surgery.
