The tricuspid valve is closed and does not summarize _'s general knowledge completely
[Sum up ]
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.
[Diagnose ]
According to the typical noise, the atrium dextrum of right ventricle increases and symptom and physical sign of systemic circulation extravasated blood, it is generally easy to make diagnosis. Pursues acoustics radiography and Doppler's supersound and is checked and can be made a definite diagnosis of, and can help to make the diagnosis of cause of disease in the supersound aroused in interest.
[Treat the measure ]
Simple tricuspid valve close completely having the intersection of lung and the intersection of artery and high pressure, such as continue, take place on the intersection of membrane and inflammation or wound person under infective heart, seldom need surgery to treat. Heart failure that other reasons of positive treatment cause, can improve the severity that the functional tricuspid valve return to and flow. When bicuspid valve pathological change accompanies artery high pressure of lung and right ventricle to expand notably, it is unusual to correct the bicuspid valve, after reducing the artery pressure of lung, the tricuspid valve can not close completely but needn't be especially dealt with; Serious organic tricuspid valve pathological change person is especially rheumatism persons who have no artery high pressure of serious lung, can implement the shaping skill of a ring or artificial heart valve and replace the skill.
[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 amalgamate artery high pressure of lung completely, 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.
