"This is a concerning finding and very well could be a vertical decompressing vein related to anomalous pulmonary venous drainage. Pulmonary venous drainage is not "phasic" like systemic veins and the waveforms could appear arterial in…"

"  Identify fetal left and right sides. From the four-chamber view, perform a gradual cephalic sweep. Identify the trachea; this structure signifies the midline of the thorax. As the 3-vessel view is being imaged, identify the aortic arch in its…"

"A couple of additional venous structures that should be interrogated as a standard on all fetal cardiac examinations are: - color and spectral Doppler of the ubilical vein and ductus venosus - color and spectral Doppler of the pulmonary venous…"

"Lisa,   Thanks for such beautiful examples and great articles. I think that this is a very helpful tip for sonographers to employ when findings are consistent with a conotruncal defect.   The thymus gland (or lack thereof) is very…"

"This is an example of a recipient twin in twin-to-twin transfusion syndrome (TTTS). The fetus developed severe right heart failure with premature closure of the ductus arteriosus (the second Doppler tracing). Laser ablation was performed to…"

"ASD?"

"The first tracing is the umbilical vasculature, the second is the ductus arteriosus."

"Lisa,We (in pediatric cardiology) typically say that when a VSD diameter (in its largest dimension) is more than 10% of the overall length of the ventricular septum in the fetal four-chamber view, and by third trimester, then it will be significant…"
