概括
在Valsalva操作或"窗效应"期间的胸前回声心脏成像 (c-TTE) 在密码性中风患者中检测右到左的分流 (RLS) 方面优越. 这种方法提供了更好的RLS检测和分级相比通过食道心电回声学 (c-TEE).
科学领域:
- 心脏病学 心脏病学
- 神经学 神经学
- 诊断成像 诊断成像 诊断成像
背景情况:
- 密码性中风 (CS) 通常涉及右向左的分流 (RLS),需要精确的检测方法.
- 卵孔 (PFO) 是CS患者RLS的常见原因.
- 对比的跨胸腔心声学 (c-TTE) 和对比的跨食道心声学 (c-TEE) 用于识别RLS.
研究的目的:
- 为了比较c-TTE和c-TEE在检测和分类CS患者的RLS中的疗效.
- 评估不同生理状态 (休息,瓦萨尔瓦操纵,"幕后效应") 对RLS检测的影响.
- 确定在CS中对RLS评估的最佳心声回声学方法.
主要方法:
- 150名CS患者接受了c-TTE和c-TEE.
- 心声检查在休息时,在瓦尔萨尔瓦演习期间,以及在"幕后效应" (后瓦尔萨尔瓦) 期间进行.
- RLS检测和半定量分类是基于左心室的微泡特征.
主要成果:
- 在瓦萨尔瓦操作期间c-TTE检测到的RLS明显多于c-TEE (83.3%对65.3%,P<.05).
- 在"幕后效应"期间的c-TTE显示出更多的PFO-RLS和比休息时更高的等级 (91.8%vs72.7%,P <.05).
- 与c-TEE相比,c-TTE在所有州都始终显示PFO-RLS的更高等级 (P < .05).
结论:
- c-TTE,特别是在Valsalva动作或"幕后效应"期间,在CS患者的RLS检测和PFO-RLS分级方面表现出优于c-TEE的优势.
- 这些增强的c-TTE状态可以作为一种实用和有效的查方法,用于CS中疑似RLS的查方法.
- 改善RLS检测可能有助于识别中风病因和指导治疗策略.

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 diagnosing...

Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms.
