In this case report, we evaluated cellular structure and the growth potential of a porcine small intestinal submucosal patch used for pulmonary artery augmentation in a 20-day-old newborn with pulmonary atresia. The patch was resected 2 months postoperatively due to apparent abnormal wall thickening and evaluated by histologic and immunohistologic staining.
