概括
在心脏计算机断层扫描血管造影 (CCTA) 上定义了正常的左心房体积 (LAV) 值. 索引的LAVmax随着年龄的增长而增加,但没有显示出性别差异,3D体积法是最可复制的.
科学领域:
- 心血管成像 - 心血管成像
- 放射学 放射学是一门学科.
- 心脏CTCT是指心脏的CT.
背景情况:
- 左心房体积 (LAV) 是心血管事件的关键预后标志物.
- 目前心脏计算机断层扫描血管学 (CCTA) 的正常LAV值尚未得到充分确立.
- 使用CCTA进行LAV评估的最佳方法需要进一步定义.
研究的目的:
- 为了确定最大缩LAV (LAVmax) 和心室尺寸的正常参考值.
- 使用CCTA将这些值按年龄,性别和身体表面积 (BSA) 规范化.
- 为了比较不同测量方法的LAVmax.
主要方法:
- 对250名没有心脏病史的健康受试者的回顾性分析.
- 通过3D体积和面积长度方法测量的LAVmax.
- 使用专用3D半自动化软件分析所有心脏腔室.
主要成果:
- 索引的LAVmax随着年龄的增长而显著增加,无论男女.
- 对于BSA指数的LAVmax,没有发现显著的性别差异.
- 3D体积法显示出比面积-长度方法更高的可重复性和更大的值.
- 为所有心室提供了跨年龄和性别类别的规范值.
- 年龄和性别影响RV终端-透缩体积和LV喷射分数.
结论:
- BSA指数的LAVmax取决于年龄,但不取决于性别.
- CCTA可靠量化LAVmax,以3D体积测量方法作为可重复性和价值的首选.
- 提供的规范性数据增强了CCTA在冠状动脉评估之外的临床实用性.

Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests
390
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...

Imaging Studies for Cardiovascular System V: CT
268
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
