What Is Cardiac Ablation?
Cardiac ablation is a minimally invasive procedure used to treat certain abnormal heart rhythms, or arrhythmias. It is commonly recommended for conditions such as atrial fibrillation (AFib), atrial flutter, and certain types of tachycardia when medication alone does not adequately control the rhythm.
During a catheter ablation procedure, a cardiologist or electrophysiologist guides thin, flexible catheters through a blood vessel, usually from the groin, to the heart. Specialized equipment identifies abnormal electrical signals, and heat or cold energy is used to create small areas of scar tissue that block these faulty signals.
Who May Need Cardiac Ablation?
Cardiac ablation may be considered for people experiencing recurrent or troublesome irregular heartbeats, rapid heart rate, atrial fibrillation, atrial flutter, or other arrhythmias. Your cardiologist will assess your symptoms, heart health, medical history, and previous treatment before recommending the procedure.
Cardiac Ablation Procedure and Recovery
The procedure generally takes several hours, depending on the type and complexity of the arrhythmia being treated. Patients are monitored after treatment and may return home the same day or stay overnight. Many people resume normal activities within a few days, although strenuous activity and heavy lifting may need to be avoided temporarily.
Benefits and Risks
Cardiac ablation can reduce abnormal heart rhythms and may improve symptoms and quality of life. However, arrhythmias can sometimes return and additional treatment may be required. Potential risks include bleeding, infection, blood-vessel injury, blood clots, stroke, and other procedure-related complications.
