概括

已修复的Fallot四重症 (rTOF) 患者表现出微妙的左心室 (LV) 和上升大动脉 (AAo) 功能障碍. 损坏的AAo菌株与rTOF幸存者的双心脏功能障碍和疾病严重程度有关.

科学领域:

心脏病学心脏病学
心声回声扫描 (Echocardiography) 是一种心声回声扫描.
医疗成像医学成像

背景情况:

由于各种因素,Fallot四重症 (TOF) 修复可能导致长期的腹腔功能障碍.
在经过修复的TOF (rTOF) 患者中评估双心室性能和心室间相互作用对于了解长期结果至关重要.

研究的目的:

为了研究rTOF患者的腹腔间相互作用.
用先进的心声回声技术评估大动脉功能的对双心室功能的影响.

主要方法:

利用2D和3D斑点跟踪回声心脏图 (STE) 来评估25名rTOF成人和25名对照者的LV和RV功能.
测量了LV/RV纵向和面积应变,LV扭曲和上升的大动脉周围应变 (AAo-CS).
与临床数据和疾病严重程度相关联的心声回声学参数.

主要成果:

rTOF患者表现出LV 3D-STE参数和AAo-CS降低,即使射出分数和大动脉尺寸正常.
AAo-CS损伤与AAo直径增加,LV扭曲减少,LV区域应变和RV纵向应变相关.
综合RV参数,LV区域应变和AAo-CS改善了运动能力受损的检测.

结论:

在成年rTOF患者中,斑点追踪回声心脏图识别了微妙的LV和上升性大动脉功能障碍.
在LV/RV菌株变化和AAo菌株损害之间存在相关性,表明相互关联的功能障碍.
LV和AAo菌株评估为评估rTOF疾病严重程度提供了增量价值.

关键词:

大动脉的功能功能.左心室的功能是没有的.修复的法洛特四部曲.右心室功能的功能.三维斑点跟踪回声心脏图谱是三维的.

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

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...
