概括

右心房附属体 (RAA) 的高隔膜前部区域为跨RAA心周 insufflation提供了最安全的接入. 这个解剖区域提供了最大的清除关键结构,如大动脉和冠状动脉.

科学领域:

心血管成像和解剖学的心血管成像
干预性心脏病学干预性心脏病学
心脏计算机断层扫描是指心脏的计算机断层扫描.

背景情况:

穿越右心房附属体 (RAA) 心周二氧化碳 (CO2) 吸入是一种可行的和安全的程序.
对于RAA穿孔的最佳位置,以获得心周通道并未得到很好地定义.

研究的目的:

确定最佳的RAA区域,以确保安全的跨RAA心周通道.
使用对比增强的心脏CT来分析RAA内的空间关系.

主要方法:

分析了50名患者对比度增强的心脏CT扫描.
将RAA分为6个段,跨越3个轴平面 (基底,中,高).
从每个RAA段到相邻的上心脏结构的测量距离.

主要成果:

侧面的RAA片段与表层心周直接接触.
后部和中部septal段是靠近大动脉.
高隔膜前部RAA区域显示出来自大动脉,右心室外流通道 (RVOT) 和右冠状动脉 (RCA) 的最大清除.

结论:

高隔膜前部RAA区域提供了最有利的解剖学清除,可以安全地通过心房进入心周.
侧面和其他隔膜RAA壁非常接近心周围膜和大动脉,这可能会带来潜在的风险.

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...
