“…Blood velocities in the heart can be examined and characterized serially throughout pregnancy. These find-ings can be useful for early detection of abnormal heart physiology and even fetal heart defects, as has been previously demonstrated in animal models such as the chicken and mouse embryo 3,4 . In these models, anomalies such as valve regurgitation have been diagnosed with the use of color Doppler.…”

“…The recording speed utilized on all studies was 100 mm/s. By modifying the angle of insonation with the steerable probe, the inflow and outflow waveforms of the diastolic filling and the systolic ejection were maximized, as has been previously described in animal models 3,4 . Color flow imaging of the Doppler signal allowed for the definition of inflow and outflow waveforms.…”

“…Doppler echocardiography is presently the most powerful tool for assessing cardiac function in chick embryos, in vivo. 30 Several studies described hemodynamic alteration in the developing chick embryonic heart, and both physiological and pathological conditions have been studied using Doppler echocardiography [48][49][50][51] to resolve the architecture and flow characteristics in the embryonic chick AV canal and OFT. 52,53 These systems have multiple modalities including B-mode, M-mode, Doppler, color flow and tissue strain that maximize the ability to visualize and extract data from cardiac tissues in small model organisms in vivo.…”

“…measurement technique, simultaneous flow signals can be modeled together to collect a pressure-volume loop data (PV loops). 50,55,56 However, applicable pressure measurement techniques are largely invasive, thus limiting the applicability of the pressure sensing techniques. Commercial Doppler Echocardiography systems are available with a typical minimum frequency of about 10 MHz.…”
