PP-02 Prenatal diagnosis of isolated redundant foramen ovale

Objective

Redundant Foramen Ovale (RFO) is a rare cardiac anomaly. In this case report; Prenatal diagnosis and management of isolated redundant foramen ovale is discussed.

Case  

During a routine mid-trimester cardiac examination, we found that the foramen ovale flap extended at least half way into the left atrium and was isolated. There were no arrhythmias during follow-up and right heart function was normal. After delivery, the baby has no hydrops or arrhythmia.

Discussion

Redundant Foramen Ovale (RFO) is defined as an abnormally redundant foramen ovale flap that extends at least halfway across the left atrium. It can cause right ventricular volume overload leading to fetal hydrops and subsequent heart failure. RFO usually occurs in isolation, but when associated with congenital heart disease it carries a poor prognosis

Conclusion

Redundant Foramen Ovale (RFO) is a rare cardiac anomaly. It can cause arrhythmias and right heart dysfunction. Most cases resolve spontaneously after birth.
