Pulmonary flow study predicts survival in pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries
In this single institution retrospective study, the relationship of PA pressure to long-term mortality was assessed in patients undergoing unifocalization for pulmonary atresia with VSD. A mean PA intraoperative pressure > 25mm Hg was associated with worse survival, and was the sole predictor of medium-term death.
