The inspection of tricuspid stenosis? 's treatment
Expand according to typical noise, atrium dextrum and symptom and physical sign of systemic circulation extravasated blood, can generally make diagnosis, the feasible right heart conduit inspection of the person who has difficulty on diagnosing, if the tricuspid valve steps difference of a diastolic pressure in 0.27kPa(2mmHg) equally The above, can diagnose as tricuspid stenosis. Should pay attention to diseases such as narrow pericarditis,etc. with the right room mucus tumour, contract to distinguish.
Auxiliary examination
1,X-ray examination The atrium dextrum is obviously expanded, lower vena cavas and azygos veins are expanded, but there is not lung arteriectasis.
2,Check in electrocardiogramThe atrium dextrum is loose, 2 and 1 lead and unite P wave high and sharp; Amalgamate mitral stenosis at the same time because of most tricuspid stenosis patients, so the electrocardiogram also often shows one pair of atriums loosely. There is no manifestation of right ventricular hypertrophy.
3,Pursue to check in the supersound aroused in interest Change of tricuspid valve similar to ones that observe at the time of the mitral stenosis, M -type supersound aroused in interest to pursue, reveal a leaf increase thick often, EF slope of the frontal lobe is slowed down, the relaxation one takes the form of contradictory sport, tricuspid valve calcification with separating one and increases thick; Two-dimentional supersound aroused in interest to pursue to diagnose relatively helpful tricuspid stenosis, its characteristic is that a leaf of relaxation takes the form of the garden and carries the form, increase thick, a leaf is movable and limited. Doppler can estimate and examine and step a pressure rank badly in supersound.
