Abstract

Present M-mode echocardiographic Doppler equipment permits visualization of structures and flow at sites that can be interrogated by Doppler. Interrogation in specific areas can be accomplished by range-gating techniques and, when the sample volume is small enough, flow within specific vessels and chambers can be evaluated. Laminar or disturbed flow can be accurately separated, and flow direction can be determined. Accurate flow quantitation is difficult at best. Incorporation of pulsed Doppler with two-dimensional echocardiography permits not only accurate placement of sample volume, but also measurement of vessel diameter and the angle (Å) of Doppler beam relative to flow direction. Flow can be quantitated from these values. The future of range-gated pulsed Doppler with two-dimensional echocardiography is uncertain. It may some day allow accurate flow measurement and non-invasive determination of the relationship of pulmonary to systemic flow in patients with shunt lesions. These accomplishments would be a valuable breakthrough in pediatric cardiology.
