- 医疗成像医学成像
- 定量心血管分析 定量心血管分析
背景情况:
- 评估三腹吐 (TR) 严重程度的定量方法需要进一步验证.
- 心脏磁共振 (CMR) 为心血管评估提供了先进的成像能力.
研究的目的:
- 评估CMR在量化TR严重性的准确性.
- 确定CMR衍生的TR严重程度与临床/生理后果之间的关联.
主要方法:
- 对335名患者进行了全面的CMR TR评估,包括吐量和分量 (TRF) 的回顾性分析.
- 收集临床,心声和实验室数据,以评估TR严重性标志物,心力衰竭 (HF) 症状和预后指标.
- TRF与心声学发现的相关性,右侧HF标志物 (例如肝功能障碍,L-ECV),右心室重塑 (RV-EDVi) 和预后得分 (TAPSE/PASP比,TRISCORE).
主要成果:
- 对于严重的TR,TRF与基于指导方针的心声学标准有很强的相关性 (p<0.001).
- 在TRF和右侧HF指标之间发现了显著的关联,包括肝功能障碍生物标志物和CMR测量的L-ECV.
- TRF与适应不良的右心室重塑 (RV-EDVi) 和不良的预后标志物如TAPSE/PASP比率和TRISCORE在不同TR严重程度上相关.
结论:
- 使用TRF对TR的CMR量化是一种经过验证的方法,与严重TR的心声学标准保持一致.
- 右侧心力衰竭和重塑的客观迹象在TRF值低至20%时表现出来,这突显了TR的生理影响.

Mitral Regurgitation II: Clinical Features and Diagnostic Tests
366
Mitral regurgitation (MR) is a valvular heart disorder in which the mitral valve fails to close tightly, allowing blood to leak backward into the heart. Understanding the clinical manifestations, assessment, diagnostic findings, and medical management of MR is crucial to effectively managing affected patients.Clinical Manifestations of Mitral RegurgitationMitral regurgitation can be acute or chronic, each presenting differently and requiring different approaches:1. Acute Mitral...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests
405
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...

Mitral Stenosis II: Clinical features and Diagnostic Tests
215
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

Mitral Regurgitation I: Introduction
415
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...
