概括
三维内心心回声学 (3D-ICE) 准确地测量左心房附属体 (LAA) 的尺寸,用于闭塞手术,显示高一致性与转食管心声学 (TEE). 这份3D-ICE指南与2D-ICE相比,改善了设备选择和程序结果.
科学领域:
- 心血管成像 - 心血管成像
- 干预心脏病学 干预心脏病学
- 心声回声扫描 (Echocardiography) 是一种心声回声扫描.
背景情况:
- 精确大小的左心房附属体 (LAA) 对于成功的皮肤封闭程序至关重要.
- 三维内心心回声 (3D-ICE) 提供多平面可视化,有可能在干预期间增强LAA成像.
- 传统的2D-ICE和跨食道心声学 (TEE) 在实时,多平面LAA评估方面存在局限性.
研究的目的:
- 为了评估3D-ICE引导的LAA封闭 (LAAO) 的程序成功.
- 评估LAA大小的程序前TEE和程序内3D-ICE之间的相关性.
- 为了比较3D-ICE与2D-ICE在指导LAAO中的性能,使用Watchman FLX设备.
主要方法:
- 一项前性研究涉及274名患者,他们用Watchman FLX接受LAAO.
- 患者的指导是2D-ICE (220名患者) 或3D-ICE (54名患者).
- 通过3D-ICE对LAA大小进行比较,与程序前TEE测量进行比较;分析了程序成功和与设备相关的终点.
主要成果:
- 对LAA着陆区的3D-ICE测量显示,与手术前的TEE值有很高的相关性 (Pearson的r=0.94,P<0.001).
- 与2D-ICE (79.1%,P=0.005) 相比,3D-ICE设备选择和最终设备尺寸之间的一致性显著更高 (96.3%).
- 程序成功率相似 (3D-ICE的98.1%与2D-ICE的97.3%),但3D-ICE显示了减少设备重新获取/重新部署和次要终点事件的趋势.
结论:
- 以3D-ICE为指导的LAAO表现出高的程序性成功和对LAA大小与TEE的优秀协议.
- 与2D-ICE相比,3D-ICE显著提高了设备尺寸选择的准确性.
- 3D-ICE为Watchman FLX设备部署提供了卓越的指导,可能减少并发症.

Cardiac Catheterization II: Right Heart Catheterization
Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
