概括
与VARIPULSE和PulseSelect系统相比,FARAPULSE脉冲场移除系统产生的微栓塞信号 (MES) 显著减少. VARIPULSE显示了无声大脑事件/损伤 (SCEs/SCLs) 的发生率最高.
科学领域:
- 心脏病学 心脏病学
- 医疗器械 医疗器械
- 神经学 神经学
背景情况:
- 沉默的大脑事件/损伤 (SCEs/SCLs) 发生在接受导管切除的~20%的心房患者中.
- 日本有三种脉冲场除 (PFA) 系统,但微栓塞信号 (MES) 发生率未得到充分研究.
研究的目的:
- 为了比较三种不同的PFA系统在心房动过程中产生的MES数量.
主要方法:
- 33名接受PFA治疗的患者被分为三个组 (FARAPULSE,PulseSelect,VARIPULSE,每组n=11).
- 冠状动脉回声心脏成像可以实时监测MES.
- 大脑MRI在手术后评估了SCE/SCL.
主要成果:
- 与PulseSelect (P=.01) 和VARIPULSE (P<.001) 相比,FARAPULSE产生的MES显著减少.
- 与PulseSelect相比,VARIPULSE在所有肺静脉中显示出更高的MES发生率,在较低的PV中显示出更多的MES.
- 多重SCE/SCL仅发生在VARIPULSE患者中 (36%),其中FARAPULSE组有一个SCE,PulseSelect组没有.
结论:
- 与FARAPULSE相比,VARIPULSE PFA系统与MES和SCE/SCL的发病率更高有关.
- 在最初的应用中,PulseSelect生成了最多的MES.
- 法拉普尔斯 (FARAPULSE) 展示了最低的MES和SCE/SCL比率.

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
492
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,...
