[Direct anastomosis between the left atrium and the right upper pulmonary vein returning anomalously to the superior vena cava].

We report a case of a 24-year-old woman who had atrial septal defect associated with partial anomalous pulmonary venous return. The right upper pulmonary vein returned anomalously to the proximal part of the superior vena cava. Direct anastomosis between the left atrium and the anomalous right upper pulmonary vein was successfully performed.
