Abstract: Dilated cardiomyopathy is a primary cause of cardiogenic death in children. Medical therapy alone proves insufficient， necessitating heart transplantation as the preferred life-saving definitive treatment. Nevertheless， transplantation does not achieve a definitive cure. Pulmonary artery banding （PAB） significantly improves cardiac function in certain pediatric patients， thereby mitigating the need for heart transplantation and showing clinical potential to cure dilated cardiomyopathy. PAB is expected to be a preferred option for the long-term or definitive treatment of pediatric dilated cardiomyopathy.

Key words: dilated cardiomyopathy, surgical treatment, pulm-onary artery banding

摘要： 扩张型心肌病是导致儿童心源性死亡的首要病因之一。单纯内科治疗疗效有限，心脏移植是挽救患儿生命的首选终点治疗方法，但难以实现真正意义上的治愈。肺动脉环缩术可使部分患儿的心功能显著改善，免于心脏移植，显示出治愈扩张型心肌病的临床潜力，有望成为儿童扩张型心肌病长期或终点治疗的优选方案。
