Paroxysmal atrial fibrillation ablation with the mutlipolar mapping and ablation catheter

Pulmonary veins (PVs) ablation is a valid treatment option for atrial fibrillation. The standard approach for PVs isolation usually requires two catheters or an electroanatomical reconstruction of the left atrium. We describe our initial experience with a single device for mapping and ablating in a patient referred to our center for the relapsing of atrial fibrillation 3 years after a previous ablation procedure. The newly available catheter MESH was safe and effective to quickly isolate two reconnected. Introduction Ablation within or around the pulmonary veins (PVs) is a valid treatment option for atrial fibrillation. Usually PVs isolation requires the combined use of a multielectrode catheter for mapping together with an ablation catheter. Alternatively a point-by-point mapping and ablation can be achieved using a three-dimensional nonfluoroscopic system.1–7 We describe the case of a patient with recurrent paroxysmal atrial fibrillation subjected to PVs ablation by using a newly available device that allows to map and ablate simultaneously with the same catheter.
