Truncal valve insufficiency is a significant risk factor for post-operative mortality following repair of truncus arteriosus. The surgical management of dysplastic and insufficient truncal valves remains an operative challenge. We report the cases of two infants with type 2 truncus arteriosus and severely dysplastic and insufficient quadricuspid truncal valves. At primary repair, their truncal valves were successfully repaired using pericardial leaflet extensions. This technique may be used in neonates with truncal valve insufficiency as part of the primary repair of truncus arteriosus.
共同动脉干瓣膜关闭不全是共同动脉干修复术后死亡的重要危险因素。发育异常且功能不全的共同动脉干瓣膜的外科治疗仍是一项手术挑战。我们报告了两例患有2型共同动脉干且四叶式共同动脉干瓣膜严重发育异常和功能不全的婴儿病例。在初次修复时，使用心包瓣叶延长术成功修复了他们的共同动脉干瓣膜。该技术可用于患有共同动脉干瓣膜关闭不全的新生儿，作为共同动脉干初次修复的一部分。
