Use of Doppler Techniques in Fetal Echocardiography

  • Owen I. MillerEmail author

Abstract

Doppler techniques including Colour Flow Doppler, Spectral Doppler and more recently Tissue Doppler are fundamental to comprehensive fetal echocardiography. Meticulous attention to technique, including angle of insonation and correct Doppler settings will result in highly reproducible and accurate data. Incorrect transducer selection, poor angle of insonation and inappropriate gain or scale settings will result in poor quality and possible inaccurate data.

Video 4.1

Full sweep of normal fetal heart with superimposed colour Flow Doppler from situs, through the four-chamber view, left and right outflow tracts and finally into the three-vessel view. Orientation: spine posterior, fetal left to right of screen (MP4 21136 kb)

Video 4.2

Five-chamber (LVOT) view, but focussing on pulmonary veins, showing simultaneous display of 2D grey-scale and colour flow Doppler. Orientation: spine to right of screen, Left ventricle inferior (MP4 3888 kb)

Video 4.3

Four chamber view focussing on inlets. Red signals represent inflow across mitral (lowermost) and tricuspid (uppermost) valves, narrow blue jet represents tricuspid regurgitation. Orientation: spine posterior, fetal left to right of screen (MP4 4215 kb)

Video 4.4

Left ventricular outflow tract view with red signal showing normal velocity anterograde flow across the aortic valve. Orientation: spine to right of screen, left ventricle inferior (MP4 3528 kb)

Video 4.5

Right ventricular outflow tract/pulmonary artery view. Left panel shows 2D greyscale, right panel shows simultaneous Colour Flow Doppler. Initially showing main pulmonary artery with normal anterograde flow, sweeping slightly more superiorly the branch pulmonary arteries clearly seen. Orientation: spine to left of screen, right side uppermost (MP4 3880 kb)

Video 4.6

Three Vessel View. Orientation: spine lowermost on screen, fetal left on right side of screen. The three vessels; the superior caval vein is seen in cross section as a dark circle, next the aorta and then pulmonary artery are seen forming a V-shape with apex to the (fetal) left of spine. Colour Flow Doppler shows anterograde flow with uniform velocity, in both aorta and pulmonary artery (MP4 3808 kb)

Video 4.7

Three Vessel View. Orientation: spine lowermost on screen, fetal left on right side of screen. There is forward flow in the aorta but proximal pulmonary artery shows (red) retrograde Colour Flow Doppler as supply comes from arterial duct due to pulmonary valve atresia (MP4 9001 kb)

Video 4.8

Sagittal aortic arch view. Orientation; spine uppermost, cephalad to left of screen, caudal to right of screen. Three major aorto-pulmonary collateral arteries are seen arising from thoracic descending aorta, in this case due to pulmonary atresia (MP4 4816 kb)
