“…CoA has been classically defined as a narrowing of the aorta in the region of the ligamentum arteriosum (11), representing a spectrum of aortic narrowing from a discrete constriction of the AOi to tubular hypoplasia, with many variations between these two extremes (12) The exact pathogenesis of RFOF remains unclear, but it may be related to a localized developmental abnormality (13) or intrauterine myocarditis (14). RFOF is associated with several congenital malformations, including fetal hydrops and atrial arrhythmias (15). RFOF may cause increased blood flow in and dilation of the right heart, leading to congenital heart failure and fetal hydrops (12).…”

“…The incidence ranges from 0.2 to 1% depending on the study population [2]. Though the etiopathogenesis is unknown, it has been postulated that a true isolated primary RFO may be due to a localized developmental abnormality [5] or an in utero insult such as myocarditis [6].…”

“…Another concern is that of the development of fetal hydrops. When an isolated FO is the only underlying cause, complete reversal of the hydrops frequently ensues with timely delivery [6,10].…”

Redundant foramen ovale (RFO) is defined as an abnormally redundant foramen ovale flap that extends at least halfway across the left atrium. The exact pathogenesis is unknown. Premature, isolated, in utero RFO is rare. The prevalence in general population is unknown as it may be easily ignored on routine fetal echocardiography. The reported frequency in fetuses referred for echocardiographic examination is 0.6-1.7%. It can cause right ventricular volume overload leading to fetal hydrops and subsequent cardiac failure. In such cases, prompt delivery depending on fetal gestational age may be instrumental for the survival of the neonate. 67% can develop cardiac arrhythmias which generally resolves at birth. The most common is premature atrial contractions though rarely, supraventricular tachycardia can also occur. RFO usually occurs in isolation but when associated with congenital heart disease, it carries a poor prognosis. Several series have reported redundant foramen ovale in echocardiographic and autopsy findings in children and adults but only few reports on the antenatal detection of isolated RFO has been described. We discuss two prenatal cases of isolated redundant foramen ovale diagnosed in the third trimester. They were followed up two weekly without development of any complications and delivered at term. After delivery, the infants had no history or symptoms of cardiac distress. Echocardiography showed a structurally normal heart. Hence, if there are no associated anomalies in a case of redundant foramen ovale, the prenatal management need not be altered.
