Highlights the importance of recognizing and appropriately managing persistent left superior vena cava as a potential arrhythmogenic source and anatomical confounder during atrial fibrillation ablation.
Awareness of left superior vena cava anatomy may avert pulmonary vein recording errors in AF ablation; extends anatomical considerations but leaves open broader validation.
Persistent left superior vena cava is a rarely seen anomaly but it may be an arrhythmogenic source for paroxysmal atrial fibrillation. Furthermore, the complex anatomicregion between the left superior vena cava and the pulmonary veins may leads to misinterpretation of the pulmonary vein recordings during atrial fibrillation ablation. Approaches that might be helpful to overcome these problems are discussed in this case report.
