Abstract

A rare but dangerous disorder that can occur at any point during pregnancy is premature closure or constriction of the foramen ovale. This syndrome can be caused by a variety of defects, either alone or in combination with other congenital and circulatory problems. Arrhythmia, right heart failure, congestion, the hypoplastic left side of the heart, pericardial and pleural effusions, ascites, and nonimmune hydrops can all be seen with early closure of the foramen ovale. Foramen ovale constriction or premature closure, which can be identified by foetal ultrasound during pregnancy, does not have any precise diagnostic criteria. To be diagnosed, a foramen ovale must be at least 2 mm in diameter, have a Doppler velocity of at least 120 cm/s, or be at least 3 mm in diameter with a Doppler velocity-measured gradient of at least 5 mm Hg.

Here, we provide a case of a single foetus at 26 weeks of gestational age with premature closure of the foramen ovale in conjunction with a restrictive atrial septal defect II type throughout the third trimester, follow-up, and normal delivery at the tertiary level of care‎.
