概括
在手术前的胸前心电回声 (TTE) 和手术后的食管内心电回声 (TEE) 之间,对于分级扩张功能障碍的一致性很差. 这突显了在手术期间评估心脏功能的潜在差异.
科学领域:
- 心脏病学 心脏病学
- 医疗成像医学成像
- 麻醉学 麻醉学
背景情况:
- 已有回声心脏学指导方针用于通过胸前回声心脏学 (TTE) 来分级腹功能障碍.
- 过食管回声心脏图 (TEE) 在手术中使用,但其与TTE对腹功能障碍分级的一致性尚不清楚.
- 这项研究评估了清醒前手术TTE和手术内TEE之间对扩张功能障碍分级的一致性.
研究的目的:
- 评估在分级扩张功能障碍时清醒前手术TTE和手术内TEE之间的一致性.
- 为了比较TTEawake和TEEanesth之间的多普勒测量,包括e'lat和E/e'lat.
主要方法:
- 98名接受心脏手术的患者通过TTE (清醒和麻醉后) 和TEE (麻醉后) 进行多普勒测量.
- 扩张功能障碍等级是主要终点,使用简化的算法和加权的 κ 统计数据进行评估.
- 二次终点 (e'lat,E/e'lat) 使用Bland-Altman一致度极限进行了比较.
主要成果:
- 观察到缺乏一致性:54%的患者显示≥1级差异,10%显示≥2级差异 (加权 κ = 0.35).
- 布兰德-阿尔特曼分析显示,e'lat和E/e'lat之间存在显著差异和广泛的共识界限.
- 36-39%的配对测量超出了可接受的协议界限.
结论:
- 清醒时的TTE和手术时的TEE之间对于分级扩张功能障碍的一致性较差.
- 需要进一步的研究来了解分歧的原因及其临床影响.
- 建议研究与不良结果相关的TTE和TEE的预后效用.

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...

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,...
