[Diversion of the inferior vena cava into the left atrium after repair of atrial septal defect with partial anomalous pulmonary venous drainage].

An 11-year-old female had operative repair of atrial septal defect associated with partial anomalous pulmonary venous drainage by direct suture at 6-year-old. Postoperatively, cyanosis and nodal bradycardia were noted by physical exercise. During 5 years thereafter, the symptoms were gradually aggravated accompanying. Cardiac catheterization revealed diversion of the inferior vena cava into the left atrium. Oxygen sampling showed right to left shunt of 22% at the atrial level. At reoperation, orifice of the inferior vena cava into the right atrium became narrow 5 mm in diameter. After enlargement of the orifice, the atrial septum was created with a Gore-Tex patch to redirect the inferior vena cava to the right atrium. Post operative course was uneventful with disappearance of the cyanosis. The patient is up and well now 9 years after reoperation.
