Catheter ablation is a procedure that treats heart rhythm problems by destroying tiny areas of heart tissue that are causing the problems. Guided by X-rays, the doctor inserts thin tubes called catheters into a blood vessel, typically in the groin or neck, and feeds them into the heart.
Wires in the catheters help the doctor identify the type of rhythm problem and find the problem areas. Then the doctor uses the wires to send energy—heat or freezing cold—to those areas. The energy destroys, or ablates, the tissue. After it's destroyed, the tissue can no longer cause a problem. The areas of tissue are very tiny. And destroying them does not affect the heart's ability to do its job.
Catheter ablation can eliminate atrioventricular nodal reciprocating tachycardia (AVNRT), a type of supraventricular tachycardia, in almost all cases.
This procedure can successfully eliminate WPW most of the time. There is a small risk of the arrhythmia recurring even after successful ablation of WPW. But a second session of catheter ablation is usually successful.
For ventricular tachycardia, catheter ablation might make the arrhythmia happen less often or stop the arrhythmia from happening again.
You may stay overnight in the hospital.
You can do light activities at home. Don't do anything strenuous until your doctor says it is okay. This may be for several days.
You may have swelling, bruising, or a small lump around the site where the catheters went into your body. These should go away in 3 to 4 weeks.
You may have to take some medicines for a while.
Your child had a catheter ablation to try to correct a problem with their heartbeat (heart rhythm).
Your child may have a bruise or a small lump where the catheters were put in. The area may feel sore for a few days after the procedure. Your child may need more sleep than usual for a few days.
At home, your child should not do any hard exercise until your doctor says it is okay. Your doctor will tell you when your child can go back to school or day care.
This procedure can be stressful for you and your child. Your child's recovery will depend on why the procedure was needed.
Your doctor inserts thin tubes called catheters into a blood vessel in your groin, arm, or neck. Then your doctor feeds them into the heart. Wires in the catheters help the doctor find the problem areas. Then the doctor uses the wires to send energy to destroy the tiny areas of heart tissue that are causing the problems.
It may seem like a bad idea to destroy parts of your heart on purpose. But the areas that are destroyed are very tiny. They should not affect your heart's ability to do its job.
You may be awake during the procedure. Or you may be asleep. The doctor will give you medicines to help you feel relaxed and to numb the areas where the catheters go in.
Catheter ablation is used for people who have persistent or recurrent fast heart rates.
Ablation might be done to treat:
Catheter ablation might be done to prevent episodes, relieve symptoms, or prevent future problems. You can decide with your doctor if the benefits of ablation outweigh the possible risks of the procedure.
This procedure usually takes 2 to 6 hours. In rare cases, it can take longer.
Procedures can be stressful for both your child and you. This information will help you understand what you can expect. And it will help you safely prepare for your child's procedure.
Problems during and after catheter ablation are not common. But the procedure has some risks. They include:
Some risks are more likely with certain types of supraventricular tachycardia (SVT). Your doctor can help you know your risk. You will have to decide whether the possible benefits of ablation outweigh these risks. Your doctor can help you decide.
Catheter ablation is a procedure that treats heart rhythm problems. These problems include atrial fibrillation, supraventricular tachycardia (SVT), atrial flutter, and ventricular tachycardia.
Your heart should have a strong, steady beat. That beat is controlled by the heart's electrical system. Sometimes that system misfires. This causes a heartbeat that is too fast and isn't steady.
Catheter ablation is a way to get into your heart and fix the problem. Ablation is not surgery.
Call 911 anytime you think your child may need emergency care. For example, call if:

Watch closely for changes in your child's health, and be sure to contact your doctor if your child has any problems.
