Title: Atrial Fibrillation Ablation: What It Gives Us Today


Atrial fibrillation (AF) is the most frequent supraventricular arrhythmia and have different forms of presentation according to its pathophysiology. The main type of is the  paroxysmal form, in which the arrithmia it is generated in the pulmonary veins, and the other type is persistent form, when the mechanisms that originate the disturbances perpetuate it in the left atrium turning into a long-lasting arrhythmia.
AF is associated with cerebrovascular accidents, acute coronary syndromes, heart failure, hospitalizations and cardiovascular death, for which numerous efforts are made to stop its evolution. Currently, antiarrhythmic drugs have a limited utility, and in case of failure, the best treatment is catheter ablation. This can be done with radiofrequency or cryoenergy and uses different strategies in paroxysmal and persistent atrial fibrillation. Electroporation is a new type of energy that presents encouraging results to become an alternative in the future. Intracardiac ultrasound was incorporated as part of atrial fibrillation ablation, allowing autonomy for the electrophysiologist and improving the safety and efficacy of the procedure. Technological progress in these techniques improves therapeutic results and the quality of life of patients with atrial fibrillation. Ours studies showed increase of acute result in the pulmonary veins isolation using contact force catheter as well as less recurrence with this technology at 2 year of follow up.
