Heart Ablation

For arrhythmias caused by abnormal heart tissue, catheter radiofrequency ablation (heat) can be used to destroy the abnormal heart tissue.

Catheters (thin, flexible tubes) are threaded through the patient's blood vessels to reach the abnormal heart tissue. The cardiologist then uses a small cutter or radiofrequency energy to remove the abnormal tissue. The procedure does not require open chest surgery.
