概括

耳前隔膜缺陷 (ASD) 关闭迅速改善右心室 (RV) 和左心室 (LV) 应变. 设备关闭显示了比手术在三个月后更好的应变恢复.

科学领域:

心脏病学心脏病学
心声回声扫描 (Echocardiography) 是一种心声回声扫描.
心脏外科手术心脏外科手术

背景情况:

分析右心室 (RV) 和左心室 (LV) 壁在心房隔膜缺陷 (ASD) 关闭后的时间应变是临床上很重要的.
在ASD患者中,RV和LV功能障碍很常见.
了解ASD关闭对心室力学的影响对于患者管理至关重要.

研究的目的:

评估ASD关闭后的RV和LV壁变形的急性和短期变化.
为了比较不同ASD关闭方法 (手术与装置) 对心室应变恢复的有效性.
评估VR和LV全球纵向应变 (GLS) 的时间演变,使用二维斑点跟踪心声学 (2D-STE).

主要方法:

对43名ASD患者和20名ASD关闭前后的对照进行了心声图.
使用二维斑点跟踪回声心电图 (2D-STE) 来测量VR和LV的全球纵向应变 (GLS).
患有自闭症的患者接受了手术关闭 (48.8%) 或设备关闭 (51.2%).

主要成果:

在基线时,与对照组相比,ASD患者的LV GLS和RV GLS显著降低.
在ASD关闭后,平均LV GLS在24小时内迅速改善,并在1个月和3个月内持续增加.
平均RV GLS在关闭后的所有串行时间点上也显著改善.
与24小时,1个月和3个月的手术关闭相比,设备关闭与更好的LV GLS和RV GLS恢复有关.

结论:

关闭ASD导致了RV和LV的重大反向改造.
二维斑点跟踪回声心电图 (2D-STE) 在评估ASD关闭后心室张力变化方面是有效的.
与手术关闭相比,设备关闭显示出更好的中期应变恢复.

Chambers of the Heart

Chambers of the Heart

The human heart is a complex organ made up of four chambers: the right and left atria and the right and left ventricles. These internal chambers are separated by partitions known as the interatrial and interventricular septa. The exterior of the heart features a groove known as the coronary sulcus that demarcates the atria from the ventricles, while the anterior and posterior interventricular sulci distinguish between the two ventricles.
Deoxygenated blood from the body is received in the right...

Imaging Studies for Cardiovascular System I:Echocardiography

Imaging Studies for Cardiovascular System I:Echocardiography

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, evaluates...

Mitral Stenosis II: Clinical features and Diagnostic Tests

Mitral Stenosis II: Clinical features and Diagnostic Tests

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...
