Catheter ablation, also known as radiofrequency ablation, is a minimally invasive procedure used to treat irregular heart rhythms, or arrhythmias. It employs heat or cold energy to make small scars in the heart that block abnormal signals and restore a normal heartbeat. At Apollo Hospitals in Jubilee Hills, Hyderabad, our expert cardiac surgeons are highly skilled in performing this procedure.
Conditions Treated
Many conditions can be treated with catheter ablation, such as:
How Does Catheter Ablation Work?
Catheter ablation involves inserting thin, flexible tubes (catheters) into blood vessels to reach the heart. These catheters record the heart’s electrical activity, allowing precise identification of the source of the arrhythmia.
Once located, the affected area of the heart muscle is ablated using either heat (radiofrequency ablation) or freezing (cryoablation). This process creates scar tissue that disrupts electrical conduction, effectively isolating the problematic area and preventing abnormal signals from affecting other parts of the heart.
Before the Procedure:
Your catheter ablation procedure will be performed in the electrophysiology lab, which resembles an operating room. You will be transported to the procedure room and asked to lie on a procedure table. Although you will be awake during the procedure, your doctor will administer sedation through a cannula in your arm to help you relax before the procedure begins.
After the Procedure
After your catheter ablation is complete, your doctor will remove the catheters, apply pressure to the insertion site, and place a dressing. You will then be closely monitored in a recovery area. Depending on your condition, you may need to rest in bed for a short period. Most patients can go home either the same day or the following morning. Many people resume normal activities, such as walking and bathing, shortly after discharge and can return to work within a day or two.
