左心耳血栓
在心房颤动患者中,由于严重心房血液淤滞、内皮功能障碍及主动机械收缩功能丧失,在左心耳(LAA)底部形成的附壁或活动性血栓。
定义
在心房颤动患者中,由于严重心房血液淤滞、内皮功能障碍及主动机械收缩功能丧失,在左心耳(LAA)底部形成的附壁或活动性血栓;代表非瓣膜性心律失常中心房血栓的主要来源,无听诊杂音或原发性内在血流动力学损害 [G810-11] [G810-12]。
严重程度标准
-
Cresti等人的研究中的字面陈述 [G810-11, Abstract]:
- “近期大型研究尚未探讨心腔内血栓形成的患病率和病因”
- “证实了其与瓣膜性心脏病或全身性高凝状态的关联”
-
Stoddard等人的研究中的字面陈述 [G810-12, Abstract]:
- “在 20 例(14%)急性心房颤动患者及 47 例(27%,p < 0.01)慢性心房颤动患者中存在左心耳血栓”
- “在持续时间 < 3 天的急性心房颤动患者中确实会发生左心房血栓”
- 心房收缩功能:无主动机械性心房排血(收缩功能 = 0)。
