Cardiac ablation is a medical procedure that can be used to treat arrhythmias. The procedure involves using techniques like catheter ablation, cryoablation, and alcohol to destroy certain areas of heart tissue that may be producing abnormal electrical signals. These areas can be visualized using techniques like cardiac mapping and echocardiography, which can identify and map any signals they may produce. Success rates can vary based on the type and location of the arrhythmia being targeted, as well as physician experience. These procedures do carry risks like heart perforation and collateral damage, but ablation is a valuable tool that can significantly improve patient outcomes and quality of life.
