Cardiac Ablation

Cardiac ablation is recommended when treatments are no longer effective or are not well tolerated to treat arrhythmias

Cardiac Ablation

Cardiac ablation is a medical procedure to treat heart rhythm disorders (arrhythmias). Using energy, either in heat (radiofrequency) or cold (cryoablation), small areas of heart tissue that cause abnormal heart rhythms or arrhythmias are eliminated. This treatment is typically performed through catheters, thin, flexible tubes inserted through veins or arteries.

What types of ablation are there?

There are several types of cardiac ablation, including:

  • Atrial flutter ablation

  • Supraventricular tachycardia ablation

  • Atrioventricular node ablation

  • Ablation for ventricular tachycardia

  • Pulmonary vein isolation

Each type focuses on treating different forms of arrhythmias.

Why do I need cardiac ablation?

Cardiac ablation is recommended when treatments are no longer effective or are not well tolerated to treat arrhythmias. It is particularly useful in situations where arrhythmias pose a high risk of serious complications.

Cardiac ablation may be necessary to treat the following heart rhythm disorders:

  • Atrial fibrillation: This is the most common heart arrhythmia. Rapid and irregular heartbeats characterize it.

  • Supraventricular tachycardia: This arrhythmia is characterized by rapid heartbeats originating in the heart's upper chambers.

  • Ventricular tachycardia: This arrhythmia is characterized by rapid heartbeats originating in the heart's lower chambers.


How do I prepare myself for cardiac ablation?

Before undergoing cardiac ablation, it is essential to follow your Cardiologist's instructions, which may include:

  • Discontinue taking certain medications.

  • Do not eat or drink anything after midnight the night before the procedure.

  • Attend a pre-operative appointment to discuss the procedure and its risks.

Before, During, and After

  • Before

Preparation includes fasting and possibly discontinuing certain medications. The procedure is performed in an electrophysiology lab (EP).

  • During

Catheters are inserted through a blood vessel, usually in the groin, and guided to the heart. Radiofrequency or cold energy is applied to treat the problem areas. Ablation takes approximately 2–4 hours, depending on the arrhythmias to be treated.

  • After

Recovery may include several hours in the hospital and possibly an overnight stay. It is recommended to avoid strenuous physical activity for a few days.

What are the results of cardiac ablation?

Cardiac ablation has a high success rate. Most patients experience a significant improvement in their quality of life, as in most cases, heart arrhythmias are resolved after the procedure.

Although there is a possibility of arrhythmia recurrence, the procedure has a high success rate. Sometimes, it may be necessary to repeat the procedure or continue with heart medication.

When should I call my Cardiologist for a cardiac ablation?

Contact your cardiologist immediately if you experience any of the following symptoms:

  • Numbness or tingling sensation in the leg where the puncture was performed, or if you notice that your foot is cold or turns blue.

  • Increased purple coloration or appearance of bruises around the area where the puncture was performed.

  • Inflammation or fluid discharge in the puncture area.

  • Pain or discomfort in the chest area that extends to the neck, jaw, or arm.

  • Stomach upset or excessive sweating.

  • Abnormally fast or irregular heart rhythm.

  • Difficulty breathing.

  • A feeling of dizziness or severe vertigo that causes you to lie down.
