Catheter intervention for abnormal pulmonary venous drainage

Transcatheter interventions for congenital heart anomalies are constantly improving. Although correction of anomalous pulmonary venous connection is routinely achieved through surgery, there are rare instances where the abnormal pulmonary vein has dual connections to both left atrium and the major systemic veins. Under these circumstances catheter based treatment might become a feasible option. We report a case of dual supply vertical vein connected to left upper pulmonary vein and innominate vein which was successfully obstructed by an occluder device leading to improvements in patient’s condition.
