Continuous Wave Doppler: Suprasternal Notch Transducer Postion

CW Beam in the Ascending Aorta

CW Beam:     In the Ascending Aorta Normal Flow:     Systolic Abnormal Findings: Increased systolic flow velocity and spectral broadening due to aortic or subaortic stenosis. Retrograde diastolic flow due to aortic insufficiency.

CW Beam in the Descending Aorta

CW Beam:  In the Descending Aorta Normal Flow:  Systolic Abnormal Finding:  Increased systolic flow velocity and spectral broadening due to coarctation of the  aorta.
