Transposition of the great arteries (TGA) is caused by discordance between the great arteries and the ventricles. If left untreated, this anomaly has a disastrous perspective. More recent surgical approach for correction includes the Lecompte technique in which the pulmonary bifurcation is transposed anterior to the aorta, which may be less physiologic. Although the early results are excellent, there is potential for future problems involving the great arteries and semilunar valves. These potential problems necessitate the development of other improved surgical techniques. Here we report an MRI 4D flow study related to a case of simple TGA whose primary surgical correction - direct spiral arterial switch operation (DSASO) - was performed twenty years ago in an attempt to restore physiologic arrangement among the great arteries and semilunar valves.
大动脉转位（TGA）是由大动脉与心室之间的不一致引起的。如果不进行治疗，这种异常情况的前景将是灾难性的。最近用于矫正的手术方法包括勒孔特技术，即肺动脉分叉转位至主动脉前方，这可能不太符合生理状态。尽管早期结果非常好，但未来涉及大动脉和半月瓣的问题仍有可能出现。这些潜在问题促使人们开发其他改进的手术技术。在此，我们报告一项与一例单纯TGA病例相关的MRI四维血流研究，该病例二十年前接受了初次手术矫正——直接螺旋动脉调转术（DSASO），旨在恢复大动脉和半月瓣之间的生理排列。
