“…Barber and colleagues from this team reported a duplex pulsed Doppler device, which combined two-dimensional echocardiography directed identification of specific targets and their interrogation with a pulsed Doppler beam. 19 The detected abnormalities included tricuspid regurgitation in a fetus with complete congenital heart block ( Figure 3), and hemodynamic abnormality associated with tetralogy of Fallot. Nanda and colleagues at the University of Rochester received the initial technical training from Baker and others at Seattle, and pioneered the application of duplex Doppler echocardiography in clinical practice.…”

Congenital heart disease (CHD), the most common congenital malformation, is associated with adverse outcome. Development of fetal echocardiography has made prenatal diagnosis of CHD a reality, and in the process revolutionized its management. This historical review briefly narrates this development over the decades focusing on the emergence of the primary modalities of fetal echocardiography comprised of the time-motion mode, two-dimensional B-mode, spectral Doppler, color Doppler, and three- and four-dimensional cardiac imaging. Collaboration between clinicians and engineers has been central to these advances. Also discussed are the accuracy and impact of fetal echocardiography on the management of CHD, and especially its role in the prenatal diagnosis of critical CHD in individualizing the management and improving the outcome. Despite these advances, most cases of CHD are not identified prenatally, emphasizing the continuing need for further technological and educational innovation and improvement.

A prospective longitudinal study dctcrmincd the physiological patterns of blood flow velocity waveforms in normal and in small-forgestational-age (SGA) fetuses. Using a Pulsed Doppler Duplex 125 norinally grown fetuses and 35 SGA fetuses were studied longitudinally at between 27 and 42 wec gestation. In normal fetuscs thc ratio between the E velocity (early p ivc vcntricular filling) and thc A velocity (active ventricular filling during atrial contraction) increased progressively during pregnancy in both transmitral and transtricuspid waveforms, approaching 1 at term. In SGA fetuses, the EiA ratios did not increasc during pregnancy and the values obtained were significantly lower than in normal fetuses. The ratio between the transtricuspid and transmitral mean temporal velocities remained almost constant throughout pregnancy in the normal fetuses with transtricuspid velocity slightly exceeding the transmitral velocity. On the other hand, in SCA fetuses the ratio between the mean tcmporal velocities was inversed with the transmitral velocity progrcssively greater than the transtricuspid velocity suggesting the existencc ol intracardiac hacmodynamic changes in thesc fetuses.With the advent of Doppler ultrasound techniques there has been an increased interest in the estimation of fetal blood flow (Eik-Nes et NI. 1980; Campbell et al. 1983). More recently range-gated pulsed Doppler ultrasound techniques have enabled human fetal intracardiac blood flow to be examined. Up to now fctal

“…In systole, a sharp peak blood flow velocity waveform was distinct in aortic and pulmonary blood flow velocity waveforms (figure 1). The maximal velocity of blood flow (MV) can be calculated by the Doppler equation: V = (Af-C)/(2f-Cos0), where V = maximal velocity, Af = frequency shift, f = transmitted ultrasound frequency and C = speed of sound in tissue [6,13]. The AT was defined as the interval between the onset of ejection and maximal velocity and the ET as the time from the onset of ejection to that of zero flow [9].…”

One-hundred and eleven Doppler echocardiographic examinations were performed on 88 normal fetuses, ranging from 16 to 41 weeks of gestation. Aortic and pulmonary maximal velocity (MV), acceleration time (AT), ejection time (ET), MV/AT (acceleration velocity: AV) and AT/ET ratio in systole were assessed on each blood flow velocity waveform. Aortic MV and pulmonary MV correlated well with gestational age, respectively. Good correlations between aortic AT, pulmonary AT and gestational age were evident. There were correlations between aortic AT/ET ratio, pulmonary AT/ET ratio and gestational age, respectively. However, there was no correlation between aortic AV, aortic ET, pulmonary AV, pulmonary ET and gestational age, respectively. These findings may relate to alterations in pulmonary and placental vascular resistance with advance in gestation.
