Lone umbilical artery indicates need for fetal ECG.(Obstetrics)(echocardiography)(Brief article)
MIAMI BEACH -- A prenatal sonographic finding of single umbilical artery is an indication for fetal echocardiography, Dr. Lami Yeo said at the annual meeting of the Society for Maternal-Fetal Medicine.
In a case series of 430 fetuses with this finding who were identified retrospectively from a database of more than 42,600 patients, 13% had sonographic structural cardiac abnormalities, said Dr. Yeo of Robert Wood Johnson Medical School, Piscataway, N.J.
About 67% of the 430 patients had isolated single umbilical artery, and the remaining 20% had only noncardiac defects, she noted.
Of the structural cardiac abnormalities, 26% were complex cardiac defects, 26% were septal defects only, 19% were left or right hypoplastic heart, 15% were conotruncal abnormalities, 6% were defects of the atrioventricular canal, and 9% were classified as "other" defects. (Percentages add to more than 100% due to ...
