Does persistent left superior vena cava (PLSVC) play a role in initiating and maintaining atrial fibrillation in patients undergoing radiofrequency catheter ablation?
Patients with atrial fibrillation undergoing pre-radiofrequency catheter ablation (RFCA) cardiac imaging
Electrophysiology study focusing on persistent left superior vena cava (PLSVC) and potential ablation
Persistent left superior vena cava (PLSVC) is present in 0.9% of AF patients and plays a significant role in AF initiation and maintenance, highlighting the value of targeted electrophysiology studies to guide ablation.
Pre-RFCA cardiac imaging revealed PLSVC in 0.9% of AF patients. This study demonstrated that PLSVC has an important role in initiating and maintaining AF in substantial proportion of patients. Electrophysiology study focusing on PLSVC can help to decide whether to ablate PLSVC.
