Experience 2007 to 2014 with catheter cryoablation for cardiac arrhythmias Does this method a role in patients with heart failure? After more than two decades of early reports using radiofrequency for the treatment of cardiac arrhythmias, our group is near to reach 7 years of experience with catheter cryoablation. When the August 8, 2007 we made the first two balloon cryoablations of South America, we were far from imagining that this method would allow us to treat such a significant number of patients of various ages with a degree of security almost ideal. Treatment of cardiac arrhythmias is usually obtained by the application of radio frequency. Unfortunately, the approaches are still very operator-dependent: the success rate is related to the experience and the number of procedures performed and is associated with a significant percentage of adverse events: embolism, cardiac tamponade, atrioesophageal fistula, left atrial tachycardia, etc. Catheter cryoablation produces fewer complications mentioned. In fact, cryoenergy has been proposed as a safe alternative to radiofrequency comparable results. Actually, it has been shown to be less thrombogenic and is associated with a very low risk of complications. Given the interest of the readers of this journal by heart failure, in this article we review about the peculiar characteristics of this technology and our series to finally focus on its role in a population with hemodynamic failure.
