[Polysplenia with anomalous pulmonary venous drainage to right atrium caused by atrial septal displacement; report of a case].
A 3-year-old girl with polysplenia, atrial septal defect (ASD), and partial anomalous pulmonary venous connection (PAPVC) was admitted to our unit to have total correction. Preoperative three-dimensional computed tomography (3D-CT) and transesophageal echo (TEE) showed that the pulmonary veins were connected with what normally constitutes the posterior wall of the left atrium, but right pulmonary veins became incorporated into the right atrium because of the atrial septal displacement. In the procedure, intracardiac inspection revealed absence of septum secondum and leftward deviation of septum primum. Deviated septum primum was incised at the posterior edge and shifted rightward to incorporate right pulmonary veins into the left atrium. ASD was closed using autologous pericardial patch. This type of PAPVC was rare and preoperative 3D-CT and TEE was quite useful in evaluating unique anatomical characteristics.
