Continuous Wave Doppler:
Apical Transducer Position
CW Beam:
In the Left Ventricular Inflow Tract and Left Atrium
Normal Flow:
Primarily diastolic
Abnormal Findings:
Increased systolic flow velocity and spectral broadening due to mitral stenosis.
High velocity retrograde systolic flow and spectral broadening due to mitral regurgitation.
CW Beam:
In the Left Ventricular Outflow Tract and Ascending Aorta
Normal Flow:
Systolic
Abnormal Findings:
Increased systolic flow velocity and spectral broadening due to aortic or subaortic stenosis.
High velocity retrograde diastolic flow and spectral broadening due to aortic insufficiency.
