• Apical five-chamber for central jets (PT-LAX for eccentric jets)
• Optimize colour flow imaging of AR
• Zoom the image of the regurgitant aortic valve
• Increase the Nyquist limit in apical views/decrease or increase in PT-LAX
• With the cine mode select the best PISA
• Display the colour off and on to visualize the AR orifice
• Measure the PISA radius at diastole using the first aliasing and along the direction of the ultrasound beam
• Measure AR peak velocity and TVI (CW)
• Calculate flow rate, EROA, R Vol
