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? >>>

 

  • Run Echocardiography Online Simulator
  • 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.
  • in the Tab <<Ao Reg>> Click Radio Button <<D mv>>
  • Click the button <<Line>> Measure Mitral Anullus Diameter. See Linear measurements.
  • Click the button <<Enter>>

 

Apical 4 chamber view. Measurement of the Mitral Annulus Diameter.

 

 

  • In the Tab <<Ao Reg>> Click Radio Button <<VTI mv>>
  • Click the button <<PW>> to start Pulse Wave doppler examination. Place Control Volume Beetwen Mitral Valve Leaflets and Click.
  • Click the button <<Curve>> place points around spectrogram of transmitral diastolic flow. See Spectral Doppler Measurements.
  • Click the button <<Enter>>

 

Apical 4 chamber view. PW Doppler. VTI mv measurement.

 

  • From the List <<Positions>> Choose Apical 5 Chamber or find the same position with 3D Transducer.
  • In the Tab <<Ao Reg>> Click Radio Button <<VTI Lvot >>
  • Click the button <<CW>> to start Continous Wave doppler examination. Place Control Volume in LVOT and Click.
  • Click the button <<Curve>> place points around spectrogram of LVOT Systolic Flow. See Spectral Doppler Measurements.
  • Click the button <<Enter>>

 

Apical 5 chamber view. CW Doppler. VTI LVOT measurement.

 

Let's Calculate EROA (Effective Regurgitant Orifice Area).

  • In the Tab <<Ao Reg>> Click Radio Button <<VTI Ao Reg >>
  • Click the button <<Curve>> place points around spectrogram of Ao regurgitation. See Spectral Doppler Measurements.
  • Click the button <<Enter>>

 

Apical 5 chamber view. CW doppler. Measurement of the VTI of Ao regurgitation.
