| 摘要: |
| 圆锥动脉干畸形患者常伴有升主动脉进行性扩张。晚期出现的主动脉瓣返流、左心功能不全甚至主动脉夹层破裂等严重并发症会增加再次手术的风险，影响患者生存。进行超声心动图或磁共振成像的定期随访，及时识别高危患者，有助于减少圆锥动脉干畸形患者主动脉相关并发症的发生，改善预后。主动脉壁力学特性的无创性评估有助于了解可能发生的主动脉病变，对灾难性主动脉事件的风险分层有重要意义。本文对圆锥动脉干畸形患者升主动脉进行性扩张的影像学评估的研究进展作一综述。 |

| Abstract: |
| Progressive aortic root dilation is very common in patients with conotruncal heart defects. Late complications like aortic regurgitation, left heart failure, and aortic dissection will amplify the risk of reoperation and affect survival. Therefore, it is necessary to have regular imaging follow-up to identify high-risk patients and reduce complications and fatality. Noninvasive evaluation of the mechanical property of ascending aorta can predict possible aortic disease and facilitate risk stratification.This article reviews the research progress of imaging evaluation of progressive aortic root dilation in conotruncal heart defects. |
