How should tricuspid stenosis be prevented?
Disease this to cause because of rheumatic fever mainly, at being clinical for have patient, rheumatic fever of disease should go on, treat actively, as to the patient who has already had rheumatism, should check strictly, consider the possibility to exist that there is tricuspid stenosis, should find early, diagnose early, treat early.
How should tricuspid stenosis treat?
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 and suitable for merging, well organized case of valve of simple juncture in the juncture of tricuspid valve. Cut-out atrium dextrum,down by knife petal before not cutting direct-view respectively it and not separate on petal and after petal and integration juncture to separate petal, disengage it into two each leaves. Petal before not cutting with after there merge being easy to be produce is juncture of petal, so should be cautious.
(2) The tricuspid valve replaces the skill and suitable for the valve and damages the deformity or shuts 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
