The purpose of the study is to evaluate, by means of MRI phase velocity imaging techniques, whether or not the modified Fontan procedure results in a more energy efficient flow pattern than does the classic Fontan operation and to provide a baseline characterization of the hemodynamic results of current surgical techniques against which future surgical modifications can be compared. The newly developed technique of MRI phase velocity imaging allows for three dimensional blood flow patterns to be depicted graphically.

本研究的目的是评价，通过MRI相速度 成像技术，无论改良Fontan程序是否导致 比经典的Fontan更节能的流动模式 操作并提供血流动力学的基线表征 当前手术技术的结果， 修改可以比较。 磁共振成像新技术 相位速度成像允许三维血流模式 以图形方式描述。
