The apical four-chamber view is frequently the first approach for a Doppler study because:
A.) It is the easiest location from which to obtain image and Doppler information.
B.) The Doppler beam is parallel to the flow through multiple valves.
C.) The transducer is closest to the valves in this position.
D.) More abnormalities can be identified from this location.
B.) There is no single "easiest" location for Doppler imaging. The transducer is closer to the valves in the parasternal views. Since the Doppler beam is parallel to the mitral, aortic, and tricuspid valves at the apex, this is a good screening location. Since may jets are eccentric, it may not be true that "more" abnormalities are detected from the apex-a low parasternal view is used very successfully with color flow.
