Assessment degree of aortic Regurgitation by Regurgitation volume and fraction (SV method)
Echocardiography Simulator
What about a little bit of theory before beginning the simulation? >>>
- From the List <<Patients>> Choose Patient 4 (User can Choose other patients with aortic regurgitation as well).
- From the List <<Positions>> Choose Parasternal Long (Left Parasternal View, Long axis of LV). or find the same position with 3D Transducer.
Left Parasternal View, the Long axis of LV. Color Doppler. Aortic regurgitation.
- Click the button <<Freeze>> to freeze image.
- Click Button <<Calculations>> Click Tab <<Ao Reg>> Click Radio Button <<D Lvot>>
- Click the button <<Line>> Measure linear size of Left Ventricular Outflow Tract (LVOT). See Linear measurements.
- Click the button <<Enter>>
Left Parasternal View. The long axis of LV. Measurement of the Left Ventricular Outflow Tract (LVOT) diameter.
- From the List <<Positions>> Choose Apical 4 Chamber or find the same position with 3D Transducer.
- Click the button <<Freeze>> to freeze image.
