概括

通过对比增强计算机断层扫描血管造影 (angio-CT) 测量的大动脉膜体积与非对比成像相关,并预测死亡率. 在接受过导管大动脉植入 (TAVI) 的患者中,较高的量与较低的一年死亡率有关.

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:

评估大动脉的对于接受过导管大动脉植入 (TAVI) 的患者至关重要.
在TAVI患者中,通过对比增强计算机断层扫描血管学 (angio-CT) 测量的大动脉膜体积的预后值仍然不清楚.

研究的目的:

为了确定对比度增强的血管-CT大动脉膜体积是否与非对比度增强的分数相关.
调查TAVI患者对比度增强的血管-CT大动脉膜体积和死亡率之间的关联.

主要方法:

在两个德国TAVI中心进行了回顾性观察研究.
使用3Mensio软件在对比度增强的血管CT上量化量,与非对比度增强的血管CT分数进行验证.
考克斯比例危险回归分析用于评估基于二分化,性别特定的体积的死亡风险.

主要成果:

包括3318名TAVI患者;非对比增强和对比增强的血管CT之间有很强的相关性 (r2=0.680,P<.001).
性别特定的中位数体积:女性为514毫米3,男性为1025毫米3.
较高的量与显著降低的一年死亡率有关 (8.8%对12.1%;调整后HR为0.86,P=.02).

结论:

与对比增强的血管CT大动脉膜体积是一种可靠的测量,与非对比增强的得分相对应得很好.
在TAVI患者中,大动脉膜体积增加与一年死亡率的降低有关,这表明预后效用.

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...

Aortic Regurgitation I: Introduction

Aortic Regurgitation I: Introduction

IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
