概括
在左心室辅助装置 (LVAD) 植入后,右心室衰竭是一个显著的风险. 使用HeartMate 3的双直肠辅助器件 (BiVAD) 支持在选定的患者中显示出有希望的生存率.
科学领域:
- 心血管外科心血管外科
- 机械循环支持 机械循环支持
- 心脏衰竭管理的管理
背景情况:
- 右心室衰竭 (RVF) 是左心室辅助装置 (LVAD) 植入后的一个关键并发症,影响患者的生存.
- 现有数据表明,与单独使用LVAD相比,双心室辅助装置 (BiVAD) 或全人工心脏 (TAH) 的生存率较低.
研究的目的:
- 为了评估HeartMate 3 (HM3) 设备植入患者需要LVAD单独与BiVAD支持的结果.
- 使用HM3设备比较LVAD和BiVAD配置之间的疗效和生存率.
主要方法:
- 2014年11月至2021年12月间在澳大利亚阿尔弗雷德医院连续植入HM3装置的患者的回顾性分析.
- 仅接受LVAD治疗的患者和接受BiVAD支持的患者之间的结局比较.
主要成果:
- 在86名患者中,65人仅接受LVAD,21人接受BiVAD支持. 平均年龄分别为56岁和49岁.
- 四年心脏移植率为LVAD的54%,为BiVAD的43%. 脑卒中发生率为3.5%,血栓发生率为5% (所有在RVAD).
- 一年的精算生存率为LVAD的85%,BiVAD的95%. 死亡率包括LVAD组中的14例死亡和BiVAD组中的1例死亡.
结论:
- 对于需要双心室机械支持的患者,HeartMate 3 BiVAD 支持提供了一个可行且令人满意的选择.
- 这些发现表明,在选定的患者群体中,使用BiVAD配置可以改善生存结果.

01:16Heart Valves
4.6K
The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

01:27Development of the Heart

The development of the human heart, a crucial organ, commences from the mesoderm on the 18th or 19th day after fertilization. This process initiates in the cardiogenic area, a group of mesodermal cells at the embryo's head end, which evolves into elongated strands known as cardiogenic cords. These cords undergo a transformation to form hollow-centered endocardial tubes.
As the embryo undergoes lateral folding, these paired tubes approach each other, merging into a single primitive heart...
