回复 13# 心超


    从1-3视频显示后侧壁、后壁基底段心肌活动不良，应该是右冠狭窄堵塞，且是一个右侧优势心；视频4显示前壁、侧壁、后壁心肌收缩下降，这提示左主干堵塞，且后降支起源于回旋支，是个左侧优势心！TEE刚入门，对心肌收缩功能的判断还不是很有把握，有不对的地方请宋老师指正！深以致谢！

Dominant Left Coronary Artery

[size=+1]                                 登录/注册后可看大图   In 15% of patients the right coronary artery (RCA) is said to be "non dominant" because it does not supply circulation to the inferior portion of the inter-ventricular septum via right posterior descending coronary artery or PDA branch.   In 8% of cases the left coronary artery (LCA) is dominant because it gives of the postero-lateral artery (PLA) and then travels to the cross-section of the AV groove and the posterior inter-ventricular (IV groove) where it gives rise to the left posterior descending coronary artery (PDA) that travels in the posterior IV groove and gives off several septal perforator branches (SP). The SP supply blood to the lower portion of the IV septum.   The dominant LCA also gives rise to the AV nodal branch which supplies blood to the AV node.    In about 7% of patients there is a co-dominant or balanced circulation in which case the RCA gives rise to the PDA and then terminates while the Cx artery gives rise to all the postero-lateral (PLA) branches. The Cx may also give rise to a left PDA that runs parallel to the PDA of the RCA.   The sinus or sino-atrial (SA) node branch originates in the proximal portion of the RCA in 60% of cases and as a left atrial branch of the Cx in the remaining 40% of cases. This is unrelated to whether a specific artery is "dominant" or not. [size=+1]                                 登录/注册后可看大图   The video on the left (below) shows a dominant left coronary artery system.

3.20---二尖瓣分区

二尖瓣的超声切面解剖
     3月20日晚上七点，在新八教学楼4003教室，宋海波老师又给我们上了TEE的第二堂大课---二尖瓣的超声切面解剖。在两小时的轻松活波的教学氛围中，在宋老师循循善诱、深入浅出的讲解下，我们学习了二尖瓣的生理解剖结构和在TEE下观察二尖瓣结构的常用超声切面，对二尖瓣的超声切面解剖有了一个直观的和理性的认识，受益匪浅。我有幸担任宋老师的助教，一起在sin-lab组给各位学员对二尖瓣的超声切面解剖进行了讲解和说明，现将上课现场图片发布供大家共享。
