概括
与输食管心电图 (TOE) 相比,心脏CT成像用于左心房尾闭塞 (LAAO) 规划是更快的,并减少了设备尺寸变化. 这两种成像方法在LAAO程序中都显示出类似的程序成功率和安全率.
科学领域:
- 心脏病学 心脏病学
- 医疗成像医学成像
- 干预程序 干预程序
背景情况:
- 左心房附属体 (LAA) 解剖学有所不同,需要精确的术前成像来检测皮肤间的LAA封闭 (LAAO).
- 过食管回声心电图 (TOE) 是标准的,但心脏计算机断层扫描 (CT) 越来越多地用于LAAO规划.
研究的目的:
- 为了比较程序前TOE与CT的结果,用于规划皮肤穿LAA封闭程序.
- 根据所选择的成像方式来评估程序的成功,安全和效率.
主要方法:
- 64名接受LAAO的患者进行了回顾性单中心队列研究.
- 在接受手术前TOE与CT的患者之间对结果的比较.
- 主要结果:程序成功和重大不良事件. 二次结果:程序时间,设备尺寸变化和着陆区直径.
主要成果:
- 在TOE和CT组之间,手术成功 (96.0%对100%) 或重大不良事件 (4.0%对5.1%) 没有显著差异.
- 与TOE相比,CT与显著缩短的手术时间 (103分 vs. 124分) 和较低的设备尺寸变化率 (7.7% vs. 28.0%) 相关.
- TOE低估了最大着陆区直径的频率高于CT (20.8毫米对比25.8毫米).
结论:
- 对于LAAO程序的程序前CT规划与更短的程序时间和更少的设备尺寸调整有关.
- 与TOE相比,CT成像可以更准确地评估着陆区直径.
- 对于LAAO来说,TOE和CT都是有效的成像模式,CT提供了潜在的效率优势.

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...

Imaging Studies for Cardiovascular System I:Echocardiography
303
Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...
