概括
心脏内心回声学 (ICE) 与食道内心回声学 (TEE) 不相差,用于预防心房动 (AF) 移除期间发生的血栓栓塞事件. 此外,ICE还证明了提高了安全性,效率和患者舒适度.
科学领域:
- 心脏病学 心脏病学
- 医疗成像医学成像
- 干预程序 干预程序
背景情况:
- 过食管回声心电图 (TEE) 是在心房动 (AF) 移除前进行血栓查的标准,但存在程序性风险.
- 心内回声心脏成像 (ICE) 是一种具有潜在的安全性和程序优势的替代成像方式.
研究的目的:
- 为了评估ICE是否与TEE在预防经过AF切除的患者周围手术性血栓栓塞事件方面不劣.
- 为了比较ICE和TEE之间的安全性,效率和患者舒适性,用于AF移除血栓查.
主要方法:
- 一个多中心随机临床试验,涉及1810名预定进行导管切除的AF成年患者.
- 患者被随机分配,通过ICE (n=906) 或TEE (n=904) 进行血栓查.
- 主要终点是周围程序性血栓栓塞事件的发生率;次要终点包括血栓检测,安全性,效率和患者舒适性.
主要成果:
- 血栓塞栓事件发生在ICE的0.4%与TEE的0.6%之间 (Pnoninferiority=.01),表明非劣势.
- ICE显示,与穿越性穿刺相关的大型出血的发生率显著降低 (0.2%对1.2%,P=.03).
- 与TEE相比,ICE减少了光镜时间,手术前的等待时间,以及患者报告的焦虑或抑郁.
结论:
- 心内回声扫描 (ICE) 是通过食道回声扫描 (TEE) 的安全和有效替代品,用于在AF切除中血查.
- 在程序安全,效率和患者舒适性方面,ICE提供了显著的优势,支持其在临床实践中的采用.

01:16Gastric Emptying
Gastric emptying occurs when the stomach gradually releases chyme into the duodenum. When the stomach is distended, it triggers the release of gastrin, a hormone that promotes gastric acid secretion to aid in digestion. Additionally, stomach distension contributes to peristaltic waves that propel gastric contents toward the pyloric region. The gastroenteric reflex, on the other hand, primarily stimulates peristalsis in the intestines, facilitating the movement of contents further along the...
01:26Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...
