Single-patch fold-back technique for augmentation of the superior vena cava in sinus venosus atrial septal defect associated with partial anomalous pulmonary venous return.

Sinus venosus atrial septal defect (ASD) is usually associated with partial anomalous pulmonary venous return (PAPVR) of the right pulmonary veins to the superior vena cava (SVC), or to the SVC-right atrial junction. Standard procedure for repair of this defect is a patch roofing of the sinus venosus ASD and rerouting of pulmonary veins. However, the presence of SVC stenosis is a complication of this technique, and SVC augmentation is necessary in some cases. We present a simple technique for concomitant closure of sinus venosus ASD associated with PAPVR and augmentation of the SVC with a single autologous pericardial patch.
