Sirs: The Eustachian valve, a remnant of the right valve of the sinus venosus, guarding the upper and anterior end of the inferior vena cava (IVC) may be of various sizes [1, 10]. A large Eustachian valve directs the caval flow toward the interatrial septum and in the presence of an atrial septal defect (ASD) or foramen ovale may cause arterial desaturation [3, 6, 7, 8]. This valve may be confusing for the surgeon when closing an ASD. We report a patient with symptoms noted years after the IVC had inadvertently been connected to the left atrium. The misconnection was diagnosed by echocardiography with contrast followed by cardiac catheterization and angiocardiography. The IVC was connected to the left atrium with the superior vena cava supplying the residual right atrium and right ventricle. The patient underwent uneventful correction of his surgically created malformation, which was probably caused by misinterpretation of a large Eustachian valve for the inferior part of the atrial...
