BACKGROUND
Limited data exist on strain changes after transcatheter aortic valve implantation (TAVI) in patients with aortic regurgitation (AR).
CASE SUMMARY
Three patients with AR undergoing TAVI showed an initial reduction in global longitudinal strain (GLS), followed by sustained GLS improvement within the first year.
DISCUSSION
Findings align with those of surgically treated patients with AR. There is a possible superiority of GLS to left ventricular end-diastolic diameter ratio in assessing patients with severe volume overload.
背景
关于经导管主动脉瓣植入术（TAVI）治疗主动脉瓣反流（AR）患者后应变变化的数据有限。
病例总结
3例接受TAVI治疗的AR患者最初表现为整体纵向应变（GLS）降低，随后在第一年期间GLS持续改善。
讨论
这些发现与接受手术治疗的AR患者的发现一致。在评估严重容量超负荷患者时，GLS可能优于左心室舒张末期直径比。
