目标.当一个多学科小组的亚专家开始微创胎儿心脏介入治疗计划时，会遇到多种技术困难。我们描述了学习曲线。研究设计. 10只妊娠绵羊接受了超声引导下的主动脉瓣球囊成形术。团队成员及其角色在整个审判过程中保持不变。记录穿刺针插入和主动脉根部进入左心室之间的时间。使用F检验评估显著性（P ≤ .05）。结果在试验过程中，将针尖准确定位在主动脉根部所需的时间显著减少，从第一次尝试的12分钟减少到最后一次尝试的1分钟（P = 0.003）。结论当一个多学科团队开始微创胎儿心脏介入治疗计划时，会遇到一个重要的学习曲线。然而，技术熟练可以通过实践来实现。有兴趣开发这样一个项目的机构应该在进行人类胎儿之前考虑在动物模型中进行实践。
Objectives. Multiple technical difficulties are encountered when a multidisciplinary team of subspecialists begins a minimally-invasive fetal cardiac interventional program. We describe the learning curve. Study Design. Ten pregnant sheep underwent ultrasound-guided balloon valvuloplasty of the aortic valve. Team members and their roles remained constant through the trial. The time between needle insertion and entrance of the left ventricle at the aortic root was recorded. F-test was used to assess significance (P ≤ .05). Results. The time required to accurately position the needle tip at the aortic root decreased significantly over the course of the trial, from 12 minutes with the first attempt to one minute with the last (P = .003). Conclusion. A significant learning curve is encountered when a multidisciplinary team begins a minimally-invasive fetal cardiac intervention program. However, technical proficiency can be achieved with practice. Institutions interested in developing such a program should consider practice in an animal model before proceeding to the human fetus.
