Persistent left sided vena cava (LSVC) can trigger atrial fibrillation. A 41 year old man with paroxysmal atrial fibrillation (PAF) and LSVC had all four pulmonary veins and his LSVC electrically isolated from the left atrium with the Pulmonary Vein Ablation Catheter (PVAC). At follow up the patient described no further episodes of PAF. Single-shot ablation catheters such as the PVAC maybe successfully and safely used for electrical isolation of a LSVC, though clearly more experience is required to comprehensively evaluate this.
