摘要内容如下:
重要性
患有不可修复的心脏瓣膜功能障碍的新生儿的治疗仍然是一个尚未解决的问题,因为没有生长的心脏瓣膜植入物。因此,植入心脏瓣膜的新生儿需要反复更换植入物,直到成人大小的瓣膜可以植入。
目的
第一个长出的心脏瓣膜植入物。
设计、设置和参与者
儿科转诊中心病例报告,随访1年以上。参与者是一名患有持续性共同动脉干和不可修复的动脉干瓣膜功能障碍的受体新生儿和一名患有缺氧缺血性脑损伤的供体新生儿。
干预
首次在人体内移植包含主动脉瓣和肺动脉瓣的心脏部分。
主要成果和措施
移植瓣膜生长和血流动力学功能。
结果
超声心动图显示部分心脏移植瓣膜的适应性生长和良好的血流动力学功能。
结论和相关性
在这名儿童中,部分心脏移植在1岁时植入了生长中的心脏瓣膜,结果良好。部分心脏移植可以改善患有不可修复的心脏瓣膜功能障碍的新生儿的治疗。

Abstracts
Importance The treatment of neonates with irreparable heart valve dysfunction remains an unsolved problem because there are no heart valve implants that grow. Therefore, neonates with heart valve implants are committed to recurrent implant exchanges until an adult-sized valve can fit.
Objective To deliver the first heart valve implant that grows.
Design, Setting, and Participants Case report from a pediatric referral center, with follow-up for more than 1 year. Participants were a recipient neonate with persistent truncus arteriosus and irreparable truncal valve dysfunction and a donor neonate with hypoxic-ischemic brain injury.
Intervention First-in-human transplant of the part of the heart containing the aortic and pulmonary valves.
Main Outcomes and Measures Transplanted valve growth and hemodynamic function.
Results Echocardiography demonstrated adaptive growth and excellent hemodynamic function of the partial heart transplant valves.
Conclusions and Relevance In this child, partial heart transplant delivered growing heart valve implants with a good outcome at age 1 year. Partial heart transplants may improve the treatment of neonates with irreparable heart valve dysfunction.
