Radiofrequency Ablation (RFA)

Overview

Radiofrequency Ablation (RFA) is a minimally invasive procedure that uses heat generated by radio waves to target and destroy abnormal tissues, nerves or pathways causing pain or irregular heart rhythms. It’s widely used to treat conditions like atrial fibrillation (AFib), chronic back pain, thyroid nodules and cervical issues. The procedure involves inserting a thin tube called a catheter to deliver controlled radiofrequency energy to the problem area.

Why Radiofrequency Ablation (RFA) Treatment is Required?

• To treat irregular heart rhythms such as AFib, SVT and atrial flutter
• For nerve ablation to relieve chronic back pain or neck pain
• To manage thyroid nodules without surgery
• For cervical ablation in women with certain uterine issues
• To treat abnormal tissue in cancer cases (radioablation)
• When medications fail or are not well-tolerated
• As an alternative to open-heart cardiac ablation surgery

Key Advantages of Radiofrequency Ablation (RFA) Treatment

• Minimally invasive and no large surgical cuts
• Quick recovery compared to traditional surgery
• Effective pain relief in chronic back and neck conditions
• Highly precise in targeting problem areas
• Lower risk of complications than surgery
• Can be repeated if symptoms return
• Often performed as a day-care procedure

How Should You Prepare Yourself Before Radiofrequency Ablation (RFA) Treatment

• Inform your doctor about all medications, especially blood thinners
• Avoid eating or drinking for 6–8 hours before the procedure
• Arrange for someone to accompany you on the day of treatment
• Discuss any allergies or previous reactions to anesthesia
• Wear comfortable, loose clothing and remove jewelry
• Follow specific instructions if it’s for heart ablation for AFib or spinal nerve ablation

How Radiofrequency Ablation (RFA) Therapy Treatment is Performed?

• A local anesthetic or light sedation is given
• A thin catheter or needle is inserted through the skin or a vein
• Guided by imaging (like X-ray or ultrasound), it reaches the targeted nerve or tissue
• Radiofrequency energy is delivered to heat and destroy the abnormal tissue
• The procedure usually takes 30 minutes to 2 hours, depending on the location

What You Can Expect Before, During and After Procedure?

• Before the Procedure:
• Light sedation or local anesthesia is given
• Area is sterilised and marked under imaging guidance
• During the Procedure:
• You may feel slight pressure or warmth but no major pain
• The doctor uses a radiofrequency generator to deliver heat
• Procedure is monitored in real time
• After the Procedure:
• You will rest for a short time in recovery
• Mild soreness, fatigue, or swelling may occur
• Most patients return home the same day
• Instructions will be given on activity limits and medications

Risk and Potential Complications

• Temporary worsening of pain (especially worse pain after RFA)
• Burning sensation or numbness in the treated area
• Bleeding or infection at the insertion site
• Risk of burning nerves in lower back if not done properly
• Rare complications like nerve damage or arrhythmias
• Tiredness or fatigue especially after heart ablation for AFib
• Uncommon side effects include cervical ablation recovery discomfort

Results/Outcomes

• Most patients experience significant pain relief within a few days to weeks
• In cardiac ablation, success rate for treating AFib or SVT is high
• Some may need repeat sessions after 6–24 months
• Helps avoid long-term pain medications or more invasive surgeries
• Improves quality of life, daily activity and sleep
• Can significantly reduce episodes of arrhythmia
