Complication and _'s symptom of tricuspid stenosis
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.
Tricuspid stenosis is nearly all the consequence of rheumatic fever, and erupt simultaneously mitral stenosis and/or a pathological change of the aorta. Like mitral stenosis, rheumatism the intersection of tricuspid stenosis and patient shut off with at various degrees tricuspid valve the whole often. The tricuspid stenosis patient's atrium dextrum is obviously expanded, the right room wall is increased thick, and there is serious whole body extravasated blood, the liver, spleen are swelling. Tricuspid stenosis nearly always exists with a pathological change of bicuspid valve or aorta at the same time, this kinds of situation last rheumatism inflammation of patient than bicuspid valve pathological change onlying and ( Or) A pathological change person of the aorta is more serious and more extensive. So prognosis generally abominable, carry on the intersection of surgery and treatment for instance, patient finally can die from the intersection of right heart and depleted, the intersection of lung and infarction or pulmonary embolism,etc. of person who go on. Simple tricuspid stenosis is extremely rare, patients do not hesitate to have obvious venous system extravasated blood, but there is not symptom one that can last a lot of years.
