摘要

Ross手术、保留主动脉瓣手术、同种移植物置换术、Bentall手术,甚至标准的主动脉瓣置换术都会损害房室束、隔膜膜或房室结的血液供应例如:在主动脉瓣置换术中,给住院医生的第一条“准则”是:“不要在主动脉环下缝合,否则病人可能会出现房室传导阻滞。”事实是,没有主动脉环,当一个无支架瓣膜必须放置在“环”中时,缝合线必须以环形的方式放置。那么,真相是什么呢?房室结和His束在哪里?

Anatomy (real anatomy) of the aortic valve replacement: when we can actually see it
Ross procedure,1 aortic valve sparing operations, homograft placement, Bentall procedures and even standard aortic valve replacement can damage the atrioventricular bundle, the membranous septum or the blood supply of the atrioventricular node.2 For instance: the first “dogma” instructed to a resident in aortic valve replacement is: “Do not put any stitches under the annulus: if you do this, the patient can develop atrioventricular block”. The fact of the matter is that there is no aortic annulus, and when a stentless valve has to be placed in the “annulus” the sutures HAVE to be placed in an annular fashion. So, what is the truth? Where are the atrioventricular node and the His Bundle?
