Sometimes x-ray is used to guide the catheters. If a patient already has a natural opening between the right and left atria (called a patent foramen ovale or PFO), it can be used to pass the catheters from the right to the left side. The cardiologist guides the catheter through the wall between the right and left atria (upper chambers of the heart). The procedure is done by putting catheters into blood vessels in the leg or groin and gently guiding them up to the heart. Cryoablation uses a catheter to freeze and destroy the tissue.Radiofrequency ablation uses a catheter to heat and destroy the tissue.How is cardiac ablation done?Ĭardiac ablation is done by radiofrequency ablation or cryoablation. Cardiac ablation helps relieve symptoms related to tachycardia, such as the heart beating too hard, too fast, or skipping beats (called palpitations), dizziness, chest discomfort and fainting (this is a rare symptom of tachycardia).Ĭardiac ablation is done by a doctor called an electrophysiologist, a type of heart doctor (cardiologist) that treats abnormal heart rhythms. People with tachycardia may have as an extra electrical circuit (pathway) that causes the heart to beat too fast. The procedure uses catheters that heat or freeze tissue to destroy a small part of the heart instead of surgery. While low rates of flutter recurrence have been published,17 these. For the common type of atrial flutter (typical atrial flutter), the success rates associated with ablation of atrial flutter are 95. Cardiac ablation treats heart conditions that cause very fast heart beats (called tachycardia). Radiofrequency catheter ablation is considered curative therapy for typical atrial flutter.
