To describe the fetal anatomic structures and cardiovascular anomalies observed in V axial plane (left ventricular outflow tract, LVOT), considered as part of the algorithm of ultrasound examination of fetal cardiovascular system (CASSEAL). CASSEAL consists in obtaining fetal nine axial sections between the inlet of umbilical vein and the output of subclavian arteries. Figure 1 describes the anatomical structures we can usually visualize in V axial plane. 492 fetal screening were obtained from 429 pregnant women: 366 (85.3%) were singleton pregnancies and 63 (14.68%) were twins. We found a total of 20 (4%) pathological cases, all associated with other cardiovascular defects. The most common abnormalities were ventricular septal defect and truncus arteriosus. We can use a systematic and protocolized exploration with axial planes in fetal abdomen and thorax, to visualize normal structures in these areas as well as the pathology presented at this level. In particular, V axial plane describes the characteristics and anomalies founded in LVOT, all associated with congenital heart or vascular diseases viewable in other axial planes. Further studies are needed to validate the usefulness of the algorithm as a tool for routine clinical use. Supporting information can be found in the online version of this abstract.
