Ablation helps control atrial fibrillation (Afib), an abnormal heart rhythm (arrhythmia) that involves fast, irregular heartbeats. This catheter-based treatment stops erratic electrical circuits in the lung (pulmonary) veins from firing into the two upper chambers of the heart (atria).
Cardiac Ablation at Cottage Health
During cardiac ablation, your doctor uses a thin, flexible tube (catheter) to halt unusual electrical signals and keep them from causing Afib. Common techniques include:
- Radiofrequency ablation (RFA)
Cryoablation: What to Expect
If you experience recurrent, symptomatic Afib or persistent Afib, your doctor may recommend cryoablation, a safe and effective treatment for both intermittent and persistent atrial fibrillation. During the procedure, a balloon catheter quickly and efficiently delivers coolant to an isolated area, which freezes tissue and shuts down unwanted electrical circuits around the pulmonary vein. You benefit from smaller incisions, less pain and faster recovery.
Radiofrequency Ablation: What to Expect
Your doctor may recommend radiofrequency ablation (RFA) if previous approaches to resolve your arrhythmia were unsuccessful. During this long-lasting and widely used procedure, your doctor threads a thin, flexible tube through a vein and into your heart. Then, a safe level of electrical current eliminates the tissue that causes abnormal heart rhythms.
