Abstract

Background: Low longitudinal strain of the ascending aorta (AAo) by cardiac magnetic resonance (CMR) predicts dilation and aortic events in Marfan syndrome (MFS) [1], possibly reflecting aortic stiffness [2]. Speckle-tracking is established for cardiac deformation, but proximal aorta applications are challenging due to wall thickness and substantial motion. We aimed to validate a purpose-specific speckle-tracking tool for root longitudinal strain analysis by comparison with CMR-derived AAo longitudinal strain and as predictor of dilation in MFS patients.

P.49斑点跟踪超声心动图主动脉根部纵向应变与心脏磁共振的比较及其对马凡氏综合征的预测价值

背景:心脏磁共振(CMR)的低升主动脉纵向应变(AAo)预测马凡综合征(MFS)[1]的扩张和主动脉事件，可能反映了主动脉僵硬[2]。斑点跟踪是建立在心脏变形，但近端主动脉的应用是具有挑战性的，由于壁厚和大量的运动。我们的目的是通过与cmr衍生的AAo纵向应变进行比较，验证用于根纵向应变分析的特定目的斑点跟踪工具，并作为MFS患者扩张的预测因子。
