MULTIDIMENSIONAL PHASE VELOCITY MRI

全身性高血压是一种常见的并发症， 修复主动脉缩窄。该研究建议使用多- 三维相速度磁共振成像，以确定 是否存在穿过主动脉弓的异常血流模式和/或 主动脉顺应性异常有助于缩窄后修复 高血压研究人群将由以下患者组成： 静息时血压正常的修补缩窄，修补缩窄 静息时高血压和正常对照。之间的关系 主动脉血流量和测量参数将提供洞察， 缩窄修复后高血压的可能机制。

Systemic hypertension is a common complication years after successful repair of coarctation of the aorta. The study proposes to use multi- dimensional phase velocity magnetic resonance imaging to determine whether abnormal blood flow patterns across the aortic arch and/or abnormal aortic compliance contribute to post-coarctation repair hypertension. The study population will consist of patients with: repaired coarctation normotensive at rest, repaired coarctation hypertensive at rest, and normal controls. The relationships between aortic blood flow and measured parameters will provide insight into possible mechanisms of hypertension after repair of coarctation.
