概括
右心室全球纵向应变 (RV GLS) <11%可以预测Fallot患者四重症的严重肺吐,有助于决定肺置换.
科学领域:
- 心脏病学 心脏病学
- 医疗成像医学成像
- 心声回声图 (Echocardiography) 是一种心声回声图.
背景情况:
- 肺部反是重复干预的首要原因,在四重法洛 (TOF) 患者.
- 目前肺置换 (PVR) 的标准依赖于心脏磁共振 (CMR) 成像.
- 需要新的心声回声学方法来评估PVR指示.
研究的目的:
- 评估三维 (3D) 心声学衍生的右心室 (RV) 指数,特别是RV全球纵向应变 (GLS),作为肺吐 (PR) 的预测指标.
- 确定RV GLS是否可以在经过修复的TOF患者中促进及时转诊PVR.
主要方法:
- 对TOF患者进行了3D斑点跟踪心声和3D体积测试,这些患者最近有CMR数据.
- 42个对照组被纳入了对心声回声学测量的基准测试.
- 从心声谱获得的RV和左心室 (LV) 体积和纵向应变被分析为预测PR的诊断准确性.
主要成果:
- 在CMR和心声回声学衍生的心室体积 (Bland-Altmann分析) 之间观察到良好的相关性.
- RV GLS <11%在预测严重的肺反方面表现出高灵敏度和特异性.
- 在LV和RV中,CMR和心声回声之间的体积差异在LV中明显不如VR.
结论:
- RV GLS显示为一种非侵入性成像生物标志物,用于评估修复TOF的PR严重程度.
- RV GLS <11%的截止值可能有助于识别需要PVR的患者.
- 虽然受样本规模限制,但这项研究为TOF管理提供了新的诊断方法.

418
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

423
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...
