According to Mayo Clinic, a cardiac ablation is a procedure performed to correct heart rhythm problems. The procedure typically employs catheters placed through a vein in the groin and threaded to the heart for the correction of structural problems that may be responsible for arrhythmia.
According to Mayo Clinic, cardiac ablation destroys tissue in the heart that is responsible for an abnormal heart rhythm. The procedure is sometimes done through open-heart surgery, but it is more frequently done through the use of catheters, which shortens the recovery time. There are numerous potential risks associated with having a cardiac ablation, such as bleeding or infection where the catheter is placed, heart puncture, damage to heart valves, stroke or heart attack, blood clots in legs or lungs, kidney damage and, in rare instances, death.
