概括

收缩的左心室 (LV) 的射出分数 (EF) 是心室动脉瘤 (VA) 切除结果的关键预测指标. 在VA手术后,LV的收缩部分的更高EF表明更好的生存率和功能改善.

科学领域:

心脏病学心脏病学
心血管外科心血管外科
医疗成像医学成像

背景情况:

前侧心室动脉瘤 (VA) 影响左心室 (LV) 收缩能力.
评估LV的残留收缩功能对于手术规划至关重要.

研究的目的:

为了评估残留收缩左心室 (LV) 的血管心脏学特征,在患有前侧心室动脉瘤 (VA) 的患者中.
为了确定LV的收缩部分的射出分数 (EF) 是否可以预测VA切除后的外科手术结果.

主要方法:

16名患有腹侧VA的患者接受了血管心脏造影.
使用双半球模型和修改的面积长度方法估计了LV的收缩 (CS) 和动脉瘤部分 (AS) 的体积.
收缩截面喷射率 (CS EF) 被计算出来.

主要成果:

收缩截面喷射率 (CS EF) 差异很大 (15%79%).
经过VA切除的CS EF<44%的患者死亡率为50%,功能改善有限.
患有CS EF>45%的患者有100%的存活率和显著的功能类改善 (NYHA).

结论:

收缩的剩余左心室 (LV) 的射出分数是心室动脉瘤 (VA) 切除后结果的重要预测因素.
更高的CS EF与手术后改善的生存率和功能状态相关.

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...
