The tricuspid valve is closed and does not sum up _'s general knowledge completely
1,Cause of disease
Tricuspid valve pathological change of the sex will be rare the day after tomorrow, no matter narrow or can not close completely, the most common cause of disease is chronic rheumatic heart disease. In rheumatism the intersection of bicuspid valve and pathological change, amalgamate tricuspid valve, close complete often, but tricuspid valve have rheumatism pathological change invade, this because whether the intersection of bicuspid valve and pathological change cause left the intersection of room and pressure increase, conduct, cause lung extravasated blood while being reverse, the artery pressure of lung is raised, the load of right room increases, cause the right ventricle to be plump and expanding finally, and lead to the fact the tricuspid valve ring is expanded, in a situation that the tricuspid valve leaf has not led frequently, can't close completely the functional tricuspid valve. Organic tricuspid valve close, break out, cause three petals of the intersection of leaf and fibrous hyperplasia repeatedly because of rheumatism all, a leaf increases thick, contracture, curling, the chorde tendinae shortens and the tricuspid valve happens and can not close completely. But often close and does not coexist completely with aorta one of bicuspid valve. In addition, the wound of the tricuspid valve, myocardium infarction of right room, membrane inflammation in the right heart, congenital abnormal development, it can cause the tricuspid valve not to close completely that the membrane in the heart is fine to melt etc..
2,Pathology:
The tricuspid valve can not be closed completely, when the right ventricle shrink, the blood flows into the atrium dextrum instead, cause capacity load and pressure load of right room to increase, lead to the fact finally the atrium dextrum is expanded, right the intersection of room and pressure rise, can make intravenous the intersection of reflux and obstacle under systemic circulation, up and down the intersection of vena cava and the intersection of reflux and blockage, pressure rise, and enable venous system extravasated blood of whole body. Tricuspid valve close completely, can make right ventricle relaxation issues of capacity increase with the intersection of right ventricle and the intersection of relaxation and issue fulling of the pressure, increasing, cause right ventricular hypertrophy, expand, and can make the right heart function depleted after all.
3,Symptom:
In the patient of the mitral stenosis, there is tricuspid valve that closes 2/3 of patient not complete as women. Mean age is 40 years old. Common symptom, in order to have difficulty in breathing, but the severity is lighter than the mitral stenosis, can not sit up straight and breathe, or sit up straight and breathe slightly.
4,Physical sign:
The intravenous anger one of neck is relatively common, account for 50-90%, the neck vein beats and accounts for 3/4, 90% of the patients have hepatomegaly. It is positive too to solicit the great majority in neck reflux of liver. The intravenous obvious intensity that beats of neck, relate to the fact that the size of hepatomegaly is depleted with the right heart to lose and compensate the intensity. The physical sign takes a favorable turn as treat. Tricuspid valve in the intersection of brestbone and right reason or left 4-5 rib the intersection of ensiform process and sometimes can close complete about 20% patient hearing and soft shrink noise, the noise is strengthened when inhaling deeply, the intensity of the noise not merely changes among patient, can also change in the same patient, the apt noise correlated to left ventricle pathological change is obscured sometimes.
