Catheter Ablation of Atrial Fibrillation

Atrial fibrillation (AF) results in irregular and sometimes fast beating of the heart. The aim of treating AF are

1. Reduction of symptoms due to irregular heart beat
2. Preventing stroke
3. Preventing long term deterioration in cardiac function

Catheter ablation of AF is a newer modality of treatment where radiofrequency lesions are given inside the heart to convert the AF to normal sinus rhythm. It has been shown in studies to maintain normal sinus rhythm, reduces the symptoms and improves the quality of life. While there are encouraging data on stroke prevention and reduction of overall mortality.

These images are some sample figures showing how an AF ablation is done. Multiple catheters are put inside the heart and the images of the heart are created. Radiofrequency lesions are given to terminate the tachycardia.
