AI Article Synopsis
- In fetuses, the Eustachian valve helps direct blood flow, but if it's too large, it can cause complications like restricting blood to the right ventricle and cyanosis after birth.
- A case study shows improvement in a baby's tricuspid valve and right ventricle function despite initial issues caused by a large Eustachian valve.
- Proper respiratory management is crucial to lower pulmonary vascular resistance, helping to reverse complications caused by the valve and improve heart function.
Article Abstract
In fetuses, the Eustachian valve directs oxygenated blood returning from the inferior vena cava into the left atrium via the foramen ovale. If too large, the Eustachian valve can restrict right ventricular inflow, as well as induce postnatal cyanosis via an interatrial right-to-left shunt. We report a fetal case of postnatal amelioration of the tricuspid valve and right ventricle hypoplasia, despite significant right ventricular hypoplasia associated with a large Eustachian valve. Application of an appropriate respiratory management regimen to help reduce pulmonary vascular resistance is of particular importance for the reversal of the right-to-left shunt via the foramen ovale and associated increases in right ventricular inflow.

During surgery for oval fossa defects, inadvertent suturing of pericardial patches to a prominent Eustachian valve diverts the inferior vena caval blood to the left atrium causing iatrogenic cyanosis. A similar complication may arise after surgery for superior sinus venosus defects. Surgical patch in a wrong plane may direct the superior vena cava towards the left atrium.

Background: The transesophageal echocardiogram (TEE) is the standard imaging modality for confirming the presence or absence of patent foramen ovale. PFO is a flap valve depending on the pressure change between the left and right atrium, which can help determine whether to open. 3D-TEE was shown to optimize the visualization of PFO.

During fetal life the right valve of the sinus venosus directs oxygenated blood from the inferior vena cava to the left atrium through the foramen ovale, until the regression of the right valve which usually occurs within the 15th week of pregnancy. Incomplete regression of the right venous valve in varying degrees can lead to different types of remnants such as the Eustachian valve, the Chiari Network and Cor Triatriatum Dexter. Prenatal diagnosis of remnants of right venous valve has only rarely been reported in the literature.
