Catheter treatment of cardiac arrhythmias is usually performed through the application of heat to eliminate the focus causing the arrhythmia. Cryoablation, on the contrary, uses the effect of freezing to eliminate local tissue causing the arrhythmia. The use of freezing-based lesions is safer and can prevent irreversible lesions. Thanks to this technology, we can safely treat arrhythmias located in areas of the heart that are near essential structures that could be irreversibly damaged if treated with heat.
