Abstract
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.
