- Abstract
<bold>Background: </bold>Persistent left superior vena cava (PLSVC) is one of the most frequently reported congenital anomalies and may be an important source of trigger of atrial fibrillation (AF).<bold>Methods: </bold>This was a multicenter retrospective experience including 28 patients with PLSVC who were referred for catheter ablation for drug-refractory symptomatic AF. Pulmonary vein and PLSVC isolation were performed (3.5-mm open irrigated tip ablation catheter at maximum power of 20 W, maximum temperature 43 °C with flow rate of 17 ml/min). Clinical outcomes such as complications and long-term freedom from AF were measured.<bold>Results: </bold>The mean age of the population was 61 ± 8 years, 21% were females, and AF duration was 60 ± 33 months. Sixty-one percent paroxysmal AF (17/28), 25% (7/28) persistent AF, and 14% (4/28) had long-standing persistent AF. There were no major complications that required any intervention. PLSVC isolation was achieved in 96% (27/28). Freedom from AF at 1 year without antiarrhythmic drugs was seen in 75% (21/28) of patients.<bold>Conclusions: </bold>In PLSVC patients with AF, segmental isolation of PLSVC appears to be feasible and safe and can translate into favorable clinical outcomes.
