Structure _ general knowledge of the tricuspid valve

Structure _ general knowledge of the tricuspid valve
The position that stands in the skill person, see the tricuspid valve is in the form of D shape through the right room, separate one to affix to straight side of a ring of D shape, covering the interventricular septum, and send out and adhere to his both ends taper portions and Xiao the Liang 'ses of the interventricular septum respectively vertically in separating a chorde tendinae playing a supporting role, and the arcual part of the tricuspid valve is affixing to free wall of the right ventricle, extend to Xiao the Liang 's along the intersection of interventricular septum and taper department. It is petals of leaf that cut apart to last the parts of scallop cracks little,petal before not dividing into and after petal, have some people have little crack too, make the intersection of tricuspid valve and the intersection of appearance and photogenic bicuspid valve shape. Just like a ring of bicuspid valve, a ring of tricuspid valve is a complicated dynamics structure too, its size and shape will change regularly during the cardiac cycle. Display and this kind variety mainly in before petals of ring and behind petals of ring. Systematic valve disease of the left heart causes the increasing of lung arterial pressure, the result causes the enlargement or function obstacle of a ring of right ventricle and tricuspid valve, cause then the sending tricuspid valve can not be closed completely. Anatomy research be lasted petals of rung before appearing patient petals of ring to be indicated whether whether it is with 5/6 and behind near petals of ring. In fact function of tricuspid valve structure and bicuspid valve is getting more similar a little,can dissecting by petal ago that be had with after there regard is petal on piece of having activity "before petals of leaf " ,Separate one and is analogous to " And then a leaf " ,Can make the tricuspid valve turn into according to the detailed conditions sometimes " Two melt " Structure,this Key's too principle of methods shaping.
