What _'s symptoms does the auxiliary examination of tricuspid stenosis have
Tricuspid stenosis (tricuspidstenosis) Rare on clinic, and the most for rheumatism membrane inflammation in the heart one and then offer as a gift and damage, often amalgamate a pathological change of bicuspid valve or aorta, simple tricuspid stenosis is rare. See more women, the overwhelming majority is caused by rheumatic fever, but rheumatism single tricuspid stenosis is extremely rare. As sequela of rheumatic fever, it is similar to mitral stenosis that pathology is changed, namely valve fiber take, increase thick, edge have superfluous living beings grow, three the intersection of valve and mutual adhesion or merge, form the narrow holes of triangle. Pathological change can also prolong and chorde tendinae and papilla skin. But intensity and range of tricuspid valve pathological change are lighter than bicuspid valve, it is rare to merge under the valve, and seldom there is calcium that is deposited. Narrow after taking shape, the obstacle happens when the blood flow flows into the right ventricle from the atrium dextrum, therefore the atrium dextrum is expanded, the pressure rises. Because of the reflux blockage of vena cava, venous pressure is raised for a long time, signs such as intravenous anger one of neck, hepatomegaly, ascites and four limbs edema,etc. appear. The right ventricle withers because of reducing in blood flow volume. When with bicuspid valve pathological change, the right ventricle is very plump.
1,X-ray examination: And then before show location photo expand right heart reason underpart right,superior vena cava it is wide for the shades to increase. Simple tricuspid stenosis, the lung is wild and clear, and there is no lung artery expanding or stagnation of the blood of lung.
2,The electrocardiogram characteristic is that P wave increases, but there is no plump phenomenon of right ventricle.
3,Pursue to check in the supersound aroused in interest: The echo wave of the tricuspid valve is similar to mitral stenosis, the tricuspid stenosis patient, the bimodal curve disappears, section EF is lowered and slowed down rapidly, present the pier kind and change. The relaxation one is abnormal through an activity, the atrium dextrum is expanded; When the end of right ventricle relaxation presses to rise, lengthen during AC. Tangent plane supersound aroused in interest to pursue, reveal tricuspid valve valve increase thick, relaxation issue open activity to be restricted.
4,The right heart conduit checks to reveal the pressure of atrium dextrum obviously increases. Atrium dextrum and right ventricle have the bad steps of a pressure of relaxation before apparent systolic phase, it is generally 0.5- 1.1kPa (4- 8mmHg) .
5,The radiography of cardiovascular vessel is checked: Locate in the atrium dextrum on the conduit top. Oblique the intersection of location and film take a photograph of slice, can reveal tricuspid valve a leaf increase thick, the activity subsided in front of the right, radiography pharmaceutical flows into the right ventricle in the relaxation one through narrow holes, and atrium dextrum radiography pharmaceutical empties time to lengthen.
