慢性主动脉瓣狭窄及反流可导致左心室重构,这些变化在瓣膜置换术后是否可逆及可逆程度是影响外科手术时机和患者预后的主要决定因素.影像技术是目前常用于评估心肌结构与功能的无创性方法,其中超声心动图及增强 CT 有助于人工瓣功能评估和左心室形变监测,心脏磁共振及PET/CT有助于识别术后心纤维化的进展及消退,这些技术综合应用可早期诊断和无创检测术后左心室逆重构,从而改善临床结局.本文综述多模态影像学技术对主动脉瓣置换术后左心室逆重构评估及应用进展.
Chronic aortic stenosis and regurgitation can cause left ventricular remodeling.Whether these changes are reversible and their reversibility after valve replacement are the main determinants affecting the timing and prognosis of surgery.Imaging techniques are commonly used to evaluate myocardial structure and function,in which echocardiography and enhanced CT are helpful to evaluate artificial flap function and monitor left ventricular deformation,while cardiac MR and PET/CT are helpful to identify the progression and regression of postoperative cardiac fibrosis.The combined application of these new techniques can improve clinical outcomes by early diagnosis and non-invasive detection of postoperative left ventricular reverse remodeling.This paper reviews the evaluation and application of multi-modal imaging techniques for left ventricular reverse remodeling after aortic valve replacement.
