Radiofrequency catheter ablation is a common treatment for a heart condition called atrial flutter, with cryoablation being another option that uses cold temperatures.
A 65-year-old man, who didn't respond to medicine for his heart issues, had a cryoablation procedure, during which doctors saw two episodes of ST-elevation, a sign of heart trouble.
The first episode was fixed by stopping the freezing process, while the second was due to a spasm in the artery and was treated with medicine. This case shows the importance of special imaging technology (ICE) to keep procedures safe.
