Does superior vena cava isolation improve ablation success in a patient with persistent atrial fibrillation and partial anomalous pulmonary venous connection?
Superior vena cava isolation may be crucial for successful ablation of persistent atrial fibrillation in patients with partial anomalous pulmonary venous connection to the SVC.

May support SVC isolation in persistent AF with anomalous RSPV drainage; hypothesis-generating for this rare anatomy.
Ectopic foci arising from pulmonary veins (PVs) are the predominant sources for the initiation and maintenance of atrial fibrillation (AF) in a vast majority of cases. However, ectopic foci also exist in the non-PV areas like superior vena cava (SVC) in 10-20% of the cases. We report the significance of SVC isolation in a patient with persistent AF and anomalous pulmonary venous connection of the right superior pulmonary vein into the SVC.
