Cryoablation is a method used to treat heart rhythm disorders by freezing the abnormal region using a cryoprobe. While radiofrequency ablation removes an abnormal focus or pathway by heating up the tissue, cryoablation does the same by cooling the tissue to sub-zero temperature. Currently the cryoprobe is much more expensive than the radiofrequency ablation system and is not as widely available. The advantage of cryoprobe is the reversibility while treating foci near to critical cardiac structure. Initial cooling to some extends blocks the conduction and helps to assess whether the treatment will be effective and whether any adjacent critical structure will be damaged. If any collateral damage is detected, all you have to do is to rewarm to undo the damage done. If no collateral damage is detected, further cooling produces a permanent treatment effect. Though the chance for collateral damage is less, the efficacy also may be a little lower than radiofrequency catheterSmall tubes introduced into the heart and blood vessels, for diagnostic and therapuetic (treatment) purposes ablationdestroying abnormal tissue by delivering radio frequency energy through an electrode catheterSmall tubes introduced into the heart and blood vessels, for diagnostic and therapuetic (treatment) purposes
