概括
在导管切除后,左心房附属体 (LAA) 的晚期电隔离会增加中风风险,即使在低风险患者中也是如此. 这一案例凸显了渐进式LAA隔离可能导致过渡性缺血性发作 (TIA) 的可能性.
科学领域:
- 心脏病学 心脏病学
- 电子生理学 电子生理学
- 医学案例报告 病例报告
背景情况:
- 对心房动进行导管切除的目的是恢复正常的心律.
- 在切除过程中,左心房附属体 (LAA) 的电隔离是已知的并发症.
- 隔离LAA可以增加血栓栓塞的风险,即使在患有低中风风险分数和鼻节律的患者中也是如此.
研究的目的:
- 报告一个罕见的LAA晚期偶发隔离病例,导致过渡性缺血性发作 (TIA).
- 为了突出逐步LAA电气隔离的潜力,遵循线性废弃策略.
- 强调考虑LAA电气状况在长期患者治疗中的重要性.
主要方法:
- 一个73岁妇女的病例报告,因为持续的心房动而接受多次导管切除疗程.
- 在第四次切除过程中利用电压映射来识别LAA电气隔离.
- 使用WATCHMAN FLX设备进行皮肤穿的LAA关闭.
主要成果:
- 患者在最初的废除疗程5年后发生了TIA,尽管保持了鼻节律.
- 电压映射显示了广泛的LA痕,并证实了LAA电图的缺失,表明LAA的晚期偶然隔离.
- 通过皮肤进行的LAA关闭成功进行,减轻了未来的血栓栓塞风险.
结论:
- 在LAA周围创造基板的线性剥离可能会随着时间的推移导致逐渐的电气隔离.
- 这种渐进的隔离可以增加血栓栓塞的风险,独立于鼻节律或基线中风风险得分.
- 在出现心房移后神经事件的患者中,应考虑晚期LAA隔离.

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations
325
The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

Acute Coronary Syndrome I: Introduction
711
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...
