OP15.09: Comparison of real‐time three‐dimensional echocardiography and spatio‐temporal image correlation in assessment of fetal interventricular septum

pulmonary vein was further to interatrial septum from the 4-chamber view, connected with left atrium obliquely. The left inferior pulmonary vein was close to descending aorta from 4-chamber view, connected with left atrium vertically. The left inferior pulmonary vein was located to anterior descending aorta from aortic arch view, and formed 90◦ angel with descending aorta. The right superior pulmonary vein was close to apical right atrium and superior vena cava from 4-chamber view, connected with left atrium. The right inferior pulmonary vein was near to spine, parallelled to interatrial septum, connected with left atrium. Conclusions: There is an advantage in visualizing and locating in fetal pulmonary veins by EFI combine with 2 dimensional echocardiography. Pulmonary veins anatomy should be checked during fetal heart examination.
