Complete repair was performed during deep hypothermic circulatory arrest. Despite positive inotropic support, patient died during early postoperative period, due to insufficient cardiac output.
For example, it remains unclear what length of time is safe for deep hypothermic circulatory arrest. Most studies have shown that children who undergo circulatory arrest for 30 minutes don't have any long-term problems.
