An irregular rhythm in the beating of the heart can cause, in addition to clots, cerebrovascular accidents, the third cause of death in our country. Although its diagnosis is not timely, atrial fibrillation is responsible for 20% of cases of embolism, and may today have a new treatment to reduce their damage.
Cryoblation is a procedure in which the source of energy applied is cold, unlike conventional therapy in which heat is usually administered using radiofrequencies.
This technique has been incorporated by the Arrhythmia Unit of the Cardiology Department of the University Hospital of Navarra , which seeks to treat atrial fibrillation in its non-persistent, paroxysmal form.
The most novel of this procedure is that it is done by freezing, in a single energy impact, and in a faster and more efficient way.
In the cryoablation procedure, the application of cold is achieved through the introduction, by means of a catheter, of a balloon filled with nitrous oxide, a compound used as a source of cold.
Once the balloon is introduced to the right place, it is inflated by means of a gas whose freezing temperature is below 40 degrees; it only has an impact on the internal perimeter of the pulmonary vein.
Among its main benefits are the following: it is a quick and simple technique, it does not need fluoroscopic navigation systems, it is performed under surface sedation, it does not require general anesthesia.
This procedure is the most advanced that exists as far as cardiovascular fibrillation is concerned and could be the guideline for new techniques that do not have to be invasive.
