Catheter Ablation

Targeted Treatment For Heart Rhythm Disorders

Catheter ablation is a minimally invasive procedure used to treat certain types of cardiac arrhythmias or abnormal heart rhythms. It works by targeting and treating very small areas of heart tissue that are responsible for abnormal electrical signals, helping restore a normal heart rhythm. At Oracle Heart & Vascular, our experienced cardiology specialists use catheter ablation using advanced imaging and heart-mapping technology for precision and safety.

What Does Catheter Ablation Treat?

Your heart has an electrical conduction system that controls when and how the heart beats. Electrical impulses normally travel in an organized pathway from the upper chambers of the heart to the lower chambers, allowing the heart to pump efficiently.

When this system does not function properly, arrhythmias (abnormal rhythms) can occur, causing the heart to beat too fast, too slow or irregularly.
Common arrhythmias treated with catheter ablation include:

  • Atrial fibrillation (AFib)

  • Supraventricular tachycardia (SVT)

  • Atrial flutter

  • Ventricular tachycardia (VT)

What Is Catheter Ablation?

Typically performed after an Electrophysiology (EP) Study, catheter ablation helps identify both the location and cause of abnormal electrical signals in the heart. During ablation, our heart and vascular specialist ablates (destroys) the areas of heart tissue that trigger abnormal rhythms. Removing these abnormal pathways allows the heart to return to a normal rhythm. The treated areas are very small and do not affect the heart’s ability to pump blood.

What Happens Before the Procedure?

When you arrive at the hospital, one of our team members will bring you to your room where you’ll complete paperwork and changing into a hospital gown.

We’ll then prepare your skin at the catheter insertion site. Our team will also:

  • Perform blood work, if necessary

  • An IV (intravenous) line placed in your arm or hand for fluids and medication

  • Medication through the IV to help you relax and feel drowsy

  • Transport to the cardiac catheterization lab when our physician is ready

What Happens During The Procedure?

The procedure typically lasts 2 to 6 hours, depending on the type of arrhythmia being treated. Some patients are fully sedated, while others receive lighter sedation depending on the procedure. During the procedure, you can expect the following:

  • Monitoring your heart rate, blood pressure and breathing

  • Numbing the catheter site site with a local anesthetic

  • Guiding the catheter to the heart using X-ray imaging (angiography)

  • Locating the exact area causing abnormal rhythm

  • Destroying the abnormal tissue with (radiofrequency) or freezing (cryoablation) energy

  • Removing the catheters and closing the insertion site

What Happens After the Procedure?

After ablation, you will return to your room where nurses will monitor heart rhythm and blood pressure. You may need to lie flat for 2 to 4 hours to prevent bleeding with pressure applied to the insertion site. If you experience temporary numbness or weakness in your leg, our team can assist you when getting up. You may be encouraged to drink fluids to help flush contrast dye from your body.

Catheter Ablation Recovery

You may go home the same day or stay overnight. If the catheter was placed in your groin, avoid sitting with the leg bent. Rest and avoid strenuous activity. Over the next 48 hours, watch for swelling or bleeding at the insertion site. Avoid bending, squatting, climbing stairs, running or lifting over 10 pounds. Take short walks (5-10 minutes) several times a day.

Catheter Ablation FAQs

To help the site heal properly and reduce the risk of infection follow the instructions below and any other care instructions closely. Contact your provider if you notice increasing pain, swelling, redness, drainage or bleeding.

  • Do not take baths, use hot tubs or swim for 7 days or until the site is fully healed
  • You may remove the dressing after 24 hours and take a shower, but avoid letting direct water spray hit the site
  • You may feel a small lump at the site if a closure device was used. This is normal and should gradually go away

Most patients may resume driving after 3 days. Your provider may give you different instructions based on your individual condition or recovery.

Our team will schedule your post-procedure follow-up visit with your cardiologist or advanced practice provider to review your recovery and heart rhythm. You should contact your provider if you experience new or worsening symptoms, chest discomfort, shortness of breath, or concerns about your procedure site.

For many patients, ablation offers better rhythm control when medications alone are not effective. Catheter ablation can provide long-term improvement for many patients with arrhythmias and may reduce or eliminate abnormal heart rhythms, improve quality of life, reduce the need for long-term medication and lower the risk of arrhythmia-related complications.
