Data were collected from ultrasound, fetal echocardiograms, genetic studies, and neonatal records.<\/jats:p><jats:p>\n          Results\u2003An ARSA was diagnosed in 22 fetuses. An ARSA was an isolated finding in 18 out of 22 cases (82%). Associated abnormal sonographic findings were found in 4 cases. All cases underwent invasive testing. In 1 of the cases, a chromosomal abnormality was detected (mos 45,X [13]\/46,X,e(X) (p22.1q22.1)). No cases of congenital heart disease were found in any of these fetuses. There were two cases in which the postnatal evaluation revealed a malformation: one case of hypospadias and 1 case of cleft palate.<\/jats:p><jats:p>\n          Conclusion\u2003The presence of an isolated ARSA is benign and is not associated with chromosomal abnormalities. The finding of ARSA, however, warrants a detailed fetal ultrasound in order to exclude major fetal abnormalities and other soft markers.<\/jats:p>","DOI":"10.1055\/s-0041-1732461","type":"journal-article","created":{"date-parts":[[2021,7,28]],"date-time":"2021-07-28T00:30:57Z","timestamp":1627432257000},"page":"452-456","source":"Crossref","is-referenced-by-count":4,"title":["Prenatal
