The assessment of fetal cardiovascular system is a persistent need in the field of perinatology. Conventional two-dimensional(2D)sonography and conventional color/power Doppler do not allow spatial visualization of the structures of interest. Conventional three-dimensional(3D)color/power Doppler can improve visualization of fetal cardiovascular system. However, its spatial resolution still remains unclear. HDliveFlow is a new 3D color/power Doppler that provides new insight for understanding and delineating delicate vasculature. It combines the advantages of spatial view of fetal heart and great vessels in addition to visualization of anatomical landmarks, such as the spine or diaphragm. HDliveFlow with glass-body rendering mode simultaneously displays gray and color Doppler images at the same scanning plane. HDlive silhouette mode provides vitreous-like clarity of the fetus. We present our experiences of using this new technique in the assessment of fetal cardiovascular system as well as some cardiac anomalies that were diagnosed with this technique. Fetal heart and great vessels, and small peripheral vessels were clearly demonstrated. Intra-cranial vessels, intra-thoracic and intra-abdominal vessels were clearly delineated. Truncus arteriosus was detected early in gestation, and idiopathic dilatation of pulmonary artery was also clearly identified. Right aortic arch, and Ebstein’s anomaly are examples of the anomalies that this technique was beneficial for their detection. In conclusion, HDliveFlow can provide better resolution and additional advents that might be valuable for the assessment of fetal cardiovascular system and detection of its anomalies.
