Isolated partial anomalous pulmonary venous drainage with an intact atrial septum is a rare finding. The authors describe their experience with three patients (ages 9, 37, and 54 years), with partial anomalous pulmonary venous connection to the superior vena cava, right atrium, and inferior vena cava, who underwent extracardiac conduit repair of this anomaly. In all three patients, a synthetic Gortex graft was used for reconstruction of the venous pathways to the left atrium. The follow-up period ranged from 10 to 82 months (mean, 42 months). All three patients were evaluated with intravenous digital angiography, transesophageal echocardiography, or both at 10, 33, and 82 months postoperatively. Patency of the grafts with no evidence of obstruction and excellent pulmonary venous flow was shown. This surgical technique is an excellent option for correction of this anomaly, and intravenous digital subtraction angiography is a useful diagnostic tool during the postoperative period to evaluate patency of the repair.
