BALLOON-CATHETER CRYOABLATION TECHNIQUE PROVES TO BE VERY EFFECTIVE FOR DEFINITIVE TREATMENT OF PAROXYSMAL ATRIAL FIBRILLATION

A 7-year followup of the largest series ever published of patients treated with the balloon-catheter cryoablation technique (114 patients) showed 87.7% of them had remained asymptomatic, in sinus rhythm, without medication.

In 97.2% of the 434 pulmonary veins treated, complete electrical disconnection of the veins with the left atrium had been accomplished, which proves that this technique is highly effective.

Dr. Jesús Paylos (Cardiac Electrophysiology Unit, Moncloa University Hospital, HLA Group), presented at the Arrhythmias 2015 World Congress in Venice the results of the largest followup known to date of patients with Paroxsmal Atrial Fibrillation, treated at this unit with the balloon-catheter cryoablation technique.

From November 2008 to July 2015, a total of 114 patients (86 men and 28 women, with an average age of 53 ± 13 and 61 ±10 years respectively) without prior cardiopathies were treated for their Paroxsmal Atrial Fibrillation using the balloon-catheter cryoablation technique. The patients had experienced progression of the arrhythmia 5 ± 5 years ago and had undergone 58 ± 66 annual episodes.

The remaining 12.3% of the 114 patients treated did at some point in the study a recurrence once they stopped taking their medication, which was definitively resolved after a second operation.

The complete work was published in the Journal of Atrial Fibrillation and in the Spanish Cardiology Review.
