The use of the multi-electrode duty-cycled radiofrequency ablation catheter PVAC for the ablation of a left atrial tachycardia.

The multi-electrode ablation catheter PVAC is used to simplify pulmonary vein isolation in patients undergoing ablation of atrial fibrillation. The use of the PVAC in cases of atrial tachycardia has not been reported before. In the present report, we present the use of the PVAC for the ablation of a left atrial tachycardia following pulmonary vein isolation. This case may suggest that the PVAC could ablate some atrial tachycardias without any adjunctive ablation catheter, given its ability to map, pace and apply energy over a relatively broad area.
