The crioablación is an advanced technique for the treatment of the not persistent atrial fibrillation (paroxysmal), where the applied energy source is cold and no heat. This technique, as indicated by experts of the unity of arrhythmias of the Department of Cardiology of the Clínica Universidad de Navarra, is a “quick and easy” treatment.

This unit, composed of the doctors José Ignacio García Bolao and Naiara Calvo Galiano, has recently incorporated a specific team to use the crioablación in this type of arrhythmias, since “the treatment is done by freezing, in a single impact energy, and a more effective way”.

The advantages it brings to the patient the technique with crioablación on radiofrequency ablation, reside in greater speed and simplicity of the procedure. Furthermore, stresses Calvo, “to perform this technique isn’t required the use of navigation systems not fluoroscopic, as with RF, necessary to know accurately the place where should be the ablation.” “It is enough a system of escopia”.

The need for a single transeptal femoral vein puncture and not two, as it is usually the case with RF, is another of the benefits it offers. In addition, the average hospital is just 48 hours, the same as with the conventional procedure and is performed under sedation surface, without the need for general anesthesia.

“The percentage of successful treatment of the paroxysmal atrial fibrillation by crioablación is equal or even better, than the one obtained with the traditional system of radio frequency, but is remarkably simple and quick, so it is applicable to a large number of patients,” adds Garcia Bolao.

Until now, the conventional method was to apply impacts of RF point to point in the entire perimeter of the Pulmonary veins, place where the arrhythmia originates. Small injuries (radiofrequency ablation) carried out around these vessels achieves interrupt the passage of electric-impulse for the irregular contraction from the Pulmonary veins to the heart cavities (left atrium).

Paroxysmal atrial fibrillation is the most common sustained arrhythmia and is characterized by the lack of coordination of the pace of contraction of the Atria, which can lead to thrombi and stroke and therefore trigger major cardiovascular complications.
