How should tricuspid stenosis treat _'s treatment
The treatment of this disease should restrain sodium salt from taking in strictly, employ diuretic and can improve symptom and physical sign of extravasated blood of the systemic circulation, especially lighten liver extravasated blood, improve liver function; If symptom is obvious, the average diastolic pressure Damien 0.53- 0.67kPa (4- 5mmHg) of right ventricle ,When being smaller than 1.5- 2.0cm2 with a area of tricuspid valve, can carry on the surgery treatment.
Treatment of tricuspid stenosis, in principle the same as mitral stenosis, but person who close expand, separate skill to be apt to tear valve, lead to the fact, shut off the wholly seriously, have not advocated employing yet at present.
(1) Cut the skill in the juncture of tricuspid valve:Suitable for merging, well organized case of valve of simple juncture. Until atrium dextrum cut-out,down direct-view it and not separate on petal by knife petal before not cutting respectively and after petal and integration juncture to separate petal, disengage it into two each leaves. Before it cut petal with after there merge being easy to be produce is juncture of petal, so should be cautious.
(2) The tricuspid valve replaces the skill:Suitable for the valve and damage the deformity or shut to the persons who can not be closed completely of cake seriously. The operation is cut-outed by the atrium dextrum. Excise valve, put suture and put artificial step of valve into basically until bicuspid valve replace skill to be same. But should notice:
A ring structure of tricuspid valve is not tough and tensile enough, it needs to take the spacer so as not to tear to wear the cotton-padded mattress type suture which sews a ring;
Can't cross a ring through the position suture of a leaf, so as not to damage and conduct bunch;
Seeing that the apt to take place postoperative thrombus of tricuspid valve, the pressure that and the valve bears and has smaller bicuspid valve position than the aorta one, it is comparatively suitable to replace the artificial living beings one
