title: "Superimposition" digital subtraction angiography: evaluation of total anomalous pulmonary venous connection.
abstract: Total anomalous pulmonary venous connection (TAPVC) has a relatively high surgical mortality, especially the infracardiac variety. A small left atrium may limit postoperative cardiac output. Superimposition of digitally subtracted angiographic (DSA) images may be used to define pulmonary venous anatomy, left atrial size, and its spatial relationship to the common pulmonary vein. The technique for acquiring superimposed digitally subtracted images and the results of two cases with infracardiac TAPVC are presented. We have found that this superimposition technique is easily performed and may provide important preoperative information in infants with TAPVC.
