概括
计算机断层扫描 (CT) 衍生的大动脉结石化 (AVC) 的先前确定的值可以在双大动脉 (BAV) 患者中识别严重的大动脉狭窄 (AS). 准确性因性别和种族而异,亚洲男性需要更高的门.
科学领域:
- 心脏病学 心脏病学
- 放射学 放射学是一门学科.
- 医疗成像医学成像
背景情况:
- 确立的CT衍生性大动脉结石化 (AVC) 和AVC密度 (AVCd) 的性别特定门,以确定严重的大动脉狭窄 (AS),主要基于三大动脉的高加索人群.
- 双主动脉 (BAV) 是一种常见的先天性异常,其对AS严重程度评估的AVC/AVCd值的影响还不清楚.
研究的目的:
- 评估现有的AVC和AVCd值的准确性,以识别BAV患者的严重AS.
- 评估性别和种族 (高加索人与亚洲人) 对BAV人口这些值的影响.
主要方法:
- 一个多中心注册中心收集了来自485名BAV患者的心声和CT数据,这些患者至少有轻度的AS和保存的左心室射出分数.
- CT衍生的AVC和AVCd与心声学衍生的AS血动力学严重程度进行了比较,以确定最佳值.
主要成果:
- 在BAV患者中确定了严重AS的性别特定值:AVC (男性:2315AU,女性:1103AU) 和AVCd (男性:561AU/cm2,女性:301AU/cm2).
- 白人患者的临界值与之前报告的值相似 (AVC男性:2208AU,女性:1230AU;AVCd男性:474AU/cm2,女性:358AU/cm2).
- 亚洲患者,特别是男性,需要更高的值 (AVC男性:2582AU,女性:924AU;AVCd男性:640AU/cm2,女性:255AU/cm2).
结论:
- 在BAV患者中,严重AS的最佳值通常与白人的三角门的值相似.
- 与以前报告的值相比,亚洲男性患有BAV可能需要更高的AVC值.
- 目前的指导值显示出很好的准确性,可以用于确认BAV患者的AS严重程度.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Imaging Studies for Cardiovascular System V: CT
45
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...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests
33
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
26
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...

Imaging Studies for Cardiovascular System III: X-Ray
219
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
