How can not tricuspid valve be closed completely to treat _'s symptom
The relativity tricuspid valve can not close completely the lighter of intensity after other valve pathological changes of original hair are corrected and managed, the recovery for some time, because the pressure of right ventricle drops, the right heart shrinks, it closes intensity not complete to mostly lighten, even disappear. But some diseases rheumatic heart disease patient, is to facilitate the low heart to arrange blood volume that the tricuspid valve returns to and flows blood flow dynamics obstacles led to the fact in postoperative several days, and then cause one of the factors of the operation death. And some the intersection of lung and the intersection of artery and high-pressure patient it is expected into result, in right heart to be depleted for a long time while being postoperative. Maintain, close completely to medium-sized degrees of tricuspid valve of the above in recent years, after other valve operations are finished, implement the shaping skill of a ring of the tricuspid valve in the same term, is in the hope of receiving more satisfactory result.
The organic tricuspid valve can not be closed completely, generally need surgery to treat. The lighter of pathological change, can look straight and cut the juncture merged, the shaping skill of ring of doing one more first; The more serious one of pathological change, should walk the valve replace the skill.
Shaping skill of the tricuspid valve: There are three kinds of commonsense methods Last skill of contracting petals of ring,along before petal with after petals of intersection and behind there take pairs of head to make to sew up 1- 2 stitch cotton-padded mattress as wound suture is petals of petals of ring, both sides liner slice, abbreviatory rings after forming . De vega skill,with bringing wound suture pairs of head that the needles along before petal with after there last double layers to cross to sew up is petals of petals of ring, both ends pass in and out the intersection of needle and carry one spacer each, tighten up suture, form , in order to shorten back petal and petals of the intersection of base and a ring ago that expand. Carpentier surrounds fixation, carpentier ring imitates the tricuspid valve and surrounds the shape, the oval semicircle ring made of stainless steel, the woven dacron for external use is wrapped up, there are different numbers. Put the cotton-padded mattress type suture along the tricuspid valve ring at the time of the operation, and then stitch to carpentier ring suitable for the number. It after being fixed can forms petal ago that be expanded with after there dwindle is petals of base petals of ring, and make the tricuspid valve resume to shutting well. Through the intersection of carpentier and ring that improve, adopt elastic material make ring, can adapt to the intersection of heart and the intersection of cycle and the intersection of room and the intersection of room and activity of ring, reduce and sew up the stress circled, thus the possibility to reduce avulsion.
