Qhov chaw aortic li qub yog dab tsi?
Hauv cov tib neeg uas muaj qhov qub aortic li qub, thaj chaw valve yog 3.0 txog 4.0 cm2. Qhov siab gradient hla lub stenotic valve yog cuam tshuam ncaj qha rau thaj tsam lub qhov dej thiab qhov chaw sib hloov [1]
Aortic VTI yog dab tsi?
SV = stroke volume, VTI = velocity time integral. Cov qauv sib piv rau kev ntsuas hauv aortic valve: SVaorta = areaLVOT • VTILVOT. Qhov cheeb tsam yog ntsuas hauv cm2. VTI muaj chav cm/kev sib cog lus thiab qhov ntim mob stroke muaj chav cm3/kev sib cog lus (piv txwv li ml/kev cog lus)

Qhov kev yws yws ntawm aortic stenosis yog qhov siab, 'pob zeb diamond zoo li' crescendo-decrescendo, midsystolic ejection yws hnov zoo tshaj plaws ntawm sab xis sab sauv ciam teb radiating rau caj dab thiab cov hlab ntsha carotid (saib daim duab hauv qab). Hauv me me aortic stenosis, yws peaks nyob rau hauv thaum ntxov systole
Dab tsi yws hnov hauv aortic stenosis?
Aortic stenosis yws yog pob zeb diamond-puab thiab systolic thiab radiates raws txoj hlab ntshav tawm. Lub suab nrov ntawm qhov yws txav mus rau S2 raws li qhov chaw nqaim. Classically, aortic stenosis yws yws zoo tshaj plaws nyob rau sab xis sab sauv ciam teb (qhov twg nws hnyav thiab nrov)
