This report describes a case of a young lady who, following extracardiac bypass between ascending and descending aorta for severe aortic coarctation, underwent 4-dimensional flow cardiac magnetic resonance, a technique that, by 3-dimensional flow assessment over time (4-dimensional), allows not only quantification of flows but also wall shear stress. In this case, increased wall shear stress was observed in the conduit's acute angle (kinking) as well as at the distal anastomosis level. The authors postulate that increased wall shear stress could help identify and risk stratify adult congenital heart disease who could develop vascular complications in the future. ().
本报告描述了一例年轻女性病例,该患者因严重主动脉缩窄接受升主动脉与降主动脉的心外搭桥手术后,接受了四维血流心脏磁共振检查,这项技术通过对血流进行随时间的三维评估(四维),不仅可以对血流进行量化,还能测量壁面剪应力。在该病例中,观察到在导管的锐角(扭结)处以及远端吻合口水平壁面剪应力增加。作者推测,壁面剪应力增加有助于识别成年先天性心脏病患者,并对其未来可能发生血管并发症的风险进行分层。()
