Diagnosis and checking _'s symptom of tricuspid stenosis
The overwhelming majority of tricuspid stenosis is caused by rheumatic fever, similar to mitral stenosis, the pathology of rheumatism tricuspid stenosis can see the chorde tendinae to merge and shorten while changing, the peak of a leaf merges, form a diaphragm one kind of holes.
Diagnose:
According to a noise of relaxation in the tricuspid valve district, combining typical neck intravenous a wave and atrium dextrum increases physical sign, can consider the diagnosis of tricuspid stenosis tentatively. Make a definite diagnosis of and depend on ultrasonic heart cardon and heart conduit inspection.
Other auxiliary examination:
1. last companion superior vena cava to increase wide at the time of tricuspid stenosis X-ray examination obviously atrium dextrum, but the right ventricle has not increased, the lung artery is not expanded, the blood of lung is reduced.
2.The electrocardiogram 2, aVF leads and unites P wave high and sharp, often> 0.25mV, briefs on the atrium dextrum loosely. There can be right rooms plump and partial right of electric axle such as amalgamating mitral stenosis.
3.The neck vein beats and pursues to have enormous a waves.
4.The supersound aroused in interest is pursued(UCG)
( 1) M type and two-dimentional UCG: The tricuspid valve leaf increases thick, echo strengthening, activity is stiff, open limitedly, the atrium dextrum is expanded, up and down vena cava and liver vein are increased widely. M Type slow down sport curve EF, slope,present petals of leaf the same as in sport.
( 2) Doppler UCG: Flow in the place in a right ventricle of tricuspid valve and take part in Taoism and take a sample, can detect the effusive frequency spectrum of a high speed of relaxation, and can measure and step one and press difference. Colored Doppler can reveal colorful efflux bunch inlaid on the two-dimentional level.
5.The heart conduit checks and separates the important diagnosis basis before treatment of the skill for the tricuspid valve. A pressure rank of average relaxation is greater than or equal to 0.27kPa( 2mmHg) badly ,Namely express the existence of tricuspid stenosis. While making heart conduit, must record the pressures of atrium dextrum and right ventricle synchronously, could determine correctly the pressure steps are bad. Breathe and change under the physiological situation and the atrium quivers or the low heart arranges the oligemic patient can influence and step the bad exactness that measures of a pressure rank under the pathologic situation. The radiography of atrium dextrum can be seen the right ventricle plentifully and delay, and can see the tricuspid valve is increased thick and the activity is limited, and the atrium dextrum wall is increased thick and the atrium dextrum internal diameter is expanded.
