What is Cardiac (Catheter) Ablation?

Cardiac ablation is a medical procedure used to treat certain heart rhythm disorders, also known as arrhythmias. During the procedure, abnormal heart tissue that causes irregular heartbeats is selectively destroyed or altered using various energy sources, such as radiofrequency or cryotherapy. This aims to restore a normal heart rhythm and improve the patient’s quality of life.

Types of Cardiac Ablation

Catheter Ablation: A catheter is inserted through a blood vessel to deliver energy to the heart tissue causing arrhythmias.
Radiofrequency Ablation: Uses radiofrequency energy to destroy abnormal heart tissue.
Cryoablation: This involves freezing the abnormal tissue to restore normal rhythm.
Laser Ablation: Laser energy is used to remove or destroy abnormal tissue in the heart.
Surgical Ablation: Performed during heart surgery to treat arrhythmias that catheter-based methods can’t manage.

Indications of Cardiac Ablation

Cardiac(Heart) ablation is recommended for individuals with specific types of abnormal heart rhythms (arrhythmias) that haven’t responded well to medications or other treatments. Common indications include:

Atrial Fibrillation (AFib): An irregular heartbeat in the upper chambers of the heart. Ablation restores normal rhythm when medications fail.
Supraventricular Tachycardia (SVT): Rapid heart rhythms above the ventricles. Ablation corrects abnormal electrical pathways.
Ventricular Tachycardia (VT): Ventricular tachycardia is a rapid heartbeats in the lower chambers. Ablation treats certain types of VT.
Atrioventricular Nodal Reentry Tachycardia (AVNRT): Abnormal pathways causing SVT. Ablation eliminates these pathways.
Accessory Pathways: Extra electrical pathways cause arrhythmias like Wolff-Parkinson-White syndrome. Ablation removes them.
Ventricular Fibrillation Risk: Ablation may reduce the risk of life-threatening arrhythmias like ventricular fibrillation.

Procedure Steps for Cardiac Ablation

During a cardiac ablation procedure, several steps are taken to diagnose and treat abnormal heart rhythms, also known as arrhythmias. Here’s an overview of what happens during a cardiac ablation:

Patient Evaluation: Medical history and tests like ECG are reviewed to identify cardiac arrhythmia.
Anaesthesia: Local anaesthesia or mild sedation is given for comfort.
Catheter Insertion: A thin catheter is inserted through a blood vessel to the heart.
Mapping: Catheters record the heart’s electrical activity to locate abnormal signals.
Energy Application: Radiofrequency or cryotherapy energy is applied to disrupt faulty electrical pathways.
Monitoring: Heart rhythm is monitored throughout to ensure successful treatment.
Verification: The medical team checks if the arrhythmia is corrected after each energy application.
Completion: Once the arrhythmia is corrected, catheters are removed.
Recovery: The patient is monitored in recovery for a few hours, with most able to go home the same day.
Follow-Up: Follow-up visits are scheduled to assess progress and make adjustments.

Who Will Treat the Cardiac Ablation Procedure?

Cardiac ablation is a specialized procedure performed by a cardiac electrophysiologist. A cardiac electrophysiologist is a cardiologist who has undergone additional training and expertise in the field of electrophysiology, which focuses on the electrical activities of the heart and the diagnosis and treatment of arrhythmias. These highly trained medical professionals have extensive knowledge of the heart’s electrical system, the various types of arrhythmias, and the techniques used in cardiac ablation procedures.

Preparing for Cardiac Ablation Surgery

Preparing for cardiac ablation surgery involves several important steps to ensure a safe and successful procedure. Here’s a comprehensive guide on how to prepare:

Consultation: Meet with a cardiac electrophysiologist to discuss your condition and treatment options.
Medical Evaluation: Complete necessary tests and imaging to assess your health.
Medication Review: Give a list of all medications, and follow guidelines about what to hold in advance of the procedure.
Fasting: Follow fasting instructions; typically, no food or drink after midnight.
Transportation: Have someone available to drive you to and from the hospital.
Stop Smoking: If you smoke, make an effort to quit or reduce before the process.
Hygiene: Take a shower prior to the procedure to reduce the risk of infection.
Clothing: Wear loose, comfortable clothes; bring only essentials.
Medication Instructions: Follow your doctor’s guidance on medications.
Consent Forms: Sign any necessary forms after understanding the procedure.
Questions: Ask your doctor any questions about the procedure and recovery.
Mental Preparation: Understand the procedure and potential outcomes.
Emotional Support: Reach out to loved ones for support and comfort.

Recovery After a Cardiac Ablation

Recovery after a cardiac ablation procedure is a gradual process that involves rest, monitoring, and adherence to your medical team’s postoperative instructions. The duration and specifics of your recovery can vary based on the type of arrhythmia treated, your overall health, and the approach used during the procedure. Here’s what you can generally expect during the recovery period:

Immediate Recovery: You will be monitored in a recovery area as you wake from anaesthesia. Dressings may be placed on catheter sites.
Observation: Vital signs and heart rhythm monitoring. Depending on the procedure, you might remain for a few hours or overnight.
Pain & Discomfort: Mild soreness or discomfort at injection sites is common and can be treated with over-the-counter pain medications.
Activity Restrictions: Rest and avoid heavy lifting or intense activities for a few days.
Follow-Up Appointments: Attend scheduled check-ups to evaluate how you are recovering and make any necessary adjustments to your medications.
Wound Care: Catheter insertion sites should always remain clean and dry to reduce the risk of infection.
Medications: Continue prescribed drugs, with possible adjustments based on progress.
Resuming Activities: You can resume light activities in a few days but avoid strenuous exercise for one to two weeks.
Driving: Refrain from driving for a day or two if anaesthesia or sedation is used.
Diet & Hydration: Maintain a balanced diet and stay hydrated to support healing.
Work: You may return to work within a few days to a week, depending on your job.
Exercise: Exercise gradually, not doing strenuous activity in the beginning.
Contact Medical Team: Reach out if you experience abnormal symptoms like bleeding, infection, chest pain, or irregular heartbeats.

Lifestyle Changes After Cardiac Ablation Procedure

After undergoing a cardiac ablation procedure, certain lifestyle changes can contribute to your overall heart health, promote healing, and decrease the risk of future heart rhythm issues. Here are some lifestyle changes to consider:

Follow Doctor’s Orders: Stick to medication and activity recommendations.
Eat Heart-Healthy: Choose fruits, vegetables, whole grains, lean proteins, and healthy fats.
Stay Hydrated: Drink plenty of water.
Exercise Regularly: Engage in moderate activities like walking or swimming.
Manage Stress: Try yoga, meditation, or deep breathing.
Maintain Healthy Weight: Healthy diet and exercise.
Quit Smoking: Smoking harms heart health and healing your lungs.
Limit Alcohol: Drink in moderation.
Monitor BP & Cholesterol: Keep levels in check.
Manage Diabetes: Control blood sugar with diet and medication.
Sleep Well: Aim for quality sleep.
Practice Hygiene: Prevent infections by staying clean.
Medication Adherence: Take medications as prescribed.
Attend Follow-Up Appointments: Keep track of your progress with your doctor.
Seek Support: Rely on family and friends for emotional support.
