The American College of Cardiology (ACC), the American Heart Association (AHA) and the Heart Rhythm Society (HRS) recommend catheter ablation for Afib patients when medication proves to be unsuccessful.
Catheter ablation is a non-surgical procedure that is performed by an electrophysiologist (EP). An EP is a cardiologist who focuses exclusively on the diagnosis and treatment of arrhythmias and determines where the abnormal tissue in your heart is located.
The EP places a catheter into your heart to pinpoint the source of the abnormal electrical signals. When the source of your Afib is located, therapeutic catheters transmit radiofrequency waves, generating enough heat to produce a small scar on the targeted part of your heart tissue. This process blocks the abnormal electrical impulses causing your heart rhythm disorder.
