What is Cardiac ablation?

10:08 - 9 April , 2021


It is a procedure that is carried out when there are conditions that alter the heart rhythm with the intention of modulating the symptoms when other types of treatments, including medicinal treatment, have not been successful. The most common type of cardiac ablation is carried out by inserting a catheter at a very low or high temperature to heal the damaged tissue and correct the condition by restoring normal heart rhythm.

Some of the most common conditions for which cardiac ablation is required are arrhythmias such as atrial fibrillation and ventricular tachycardia.

Preoperative preparation:

Your ABC doctor will review your medical history, perform a physical examination, and request complementary studies in order to evaluate your heart disorder, explaining the risks of the procedure. Please remember the following:

  • Notify him or her of any allergies or reactions you have or previously had.
  • If you have a pacemaker or implanted defibrillator, tell him or her if you should have any considerations.
  • If you are under medicinal treatment, ask if you can continue with it before the procedure.

Postoperative recovery:

The procedure will require you to be sedated or under general anesthesia and will often last 3 to 6 hours. 

At the end of the procedure, you could experience slight discomfort in the chest, headache, and fatigue, so you will need to recover for a few hours in another room under medical supervision to attend to any discomfort or complication. 

In some cases, you may be able to leave the hospital that same day, although the recovery period will usually be two to three days before you can return to your daily activities. 

Potential complications:

Although cardiac ablation through catheter is normally safe, as in any intervention, there could be complications such as: 

  • Heart attack.
  • Clot formation or bleeding.
  • Damage to arteries, nerves, or valves. 

The main purpose of this procedure is to restore normal heart rhythm and improve your quality of life, although they may recommend follow-up studies or maintain medicinal treatment. 

To keep your heart healthy, your ABC doctor will show you the steps to follow.
