The tricuspid valve can not close completely disease and sum up _'s general knowledge
The tricuspid valve can not be closed completely (tricuspid insufficiency) It is given much trouble in leaf that rare, and expanded by artery high pressure of lung and tricuspid valve moring causes. Common at prominent bicuspid valve pathological change and chronic lung worry.
Pathology of cause of disease
The tricuspid valve can not close completely. Common at prominent bicuspid valve pathological change and chronic lung worry, involve playing myocardial infarction of wall of right ventricle, rheumatism or heart failure later period when the congenital heart disease lung artery causes under high pressure, ischemic heart disease, myocardium disease; I haven't seen you for a long time if out of shape that the valve is shortened after rheumatism tricuspid valve inflammation, often amalgamate tricuspid stenosis; Inborn Ebstein deformity; The valve due to membrane inflammation is damaged in the infective heart; The tricuspid valve prolapses, this kind of patient prolapse with the bicuspid valve more, common at horse's all syndrome; Also can be seen at atrium dextrum mucus tumour, after right ventricle myocardial infarction and chest traumatism.
The tricuspid valve with simple sex can not close completely the day after tomorrow, because kinds of spot piece often calm ventricle of tricuspid valve cancer, enable a sharp and right ventricle wall adhesion, thus cause tricuspid valve close completely, many to have the intersection of lung and the intersection of artery and a pathological change at the same time patient this kind of. It often has right hearts that obviously expands that the tricuspid valve can not be closed completely.
Clinical manifestation
It does not cause pathology physiological change and bicuspid valve of the right side heart to close the not complete impact on left heart similarly completely that the tricuspid valve is closed, but compensate one is relatively long; If the condition develops gradually, can lead to the fact finally right ventricle and atrium dextrum are loose, the right ventricle is depleted. Persons who cause under high pressure of prominent lung artery, the condition is developed very fast.
(1) When the symptom tricuspid valve is closed and does not all amalgamate artery high pressure of lung, can present the heart and arrange reducing and symptom of systemic circulation extravasated blood of blood volume. The tricuspid valve is closed and does not amalgamate the disease patient of bicuspid valve completely, symptom of lung extravasated blood can be lightened because the tricuspid valve close the development not complete, but it can be more serious that weak and other hearts arrange the reduced symptom of blood volume.
(2) Physical sign main physical sign for the intersection of brestbone and left the intersection of bottom flange and the whole the intersection of systolic phase and noise, inhale and oppress noise can strengthen behind the liver; But if the depleted right ventricle can't increase the heartbeat amount noise difficult to strengthen. Only when the flow is very large, there are the third heart sound and medium noise of the low-key relaxation of the tricuspid valve district. Intravenous pulse wave picture v wave (are also called the reflux wave, while shrinking for the right ventricle, the blood flows back to due to right room systemic vein) of neck Increase; Can lay one's hand on and liver beat. When the valve prolapses, can hear in the tricuspid valve district and not the injection loudspeaker sound of click. Its physical sign of extravasated blood is depleted and the same as the right heart.
