EP12.09: Utility of novel fetal echocardiographic measurement formula to detect coarctation of the aorta in fetus: a retrospective single centre experience.

Ratios of RV: LV length (RV/LV), pulmonary: aortic valve diameter (PV/AV), tricuspid: mitral valve diameter, ductal: isthmus diameter (DA/isth.) and carotid-subclavian artery index (CS index) were calculated. we compared the fetal cardiac dimension measurements among the groups. The formula, which means PV/AV * DA/isth. * 1/CS index, predicted the need of CoA repair after birth (P < 0.001; CoA group: 6.4±3.5, non-CoA group: 1.8±0.7). [Extracted from the article]
