What cardiac RFA is and who needs it

Radiofrequency ablation of the heart (RFA) is a minimally invasive treatment for heart rhythm disorders. Special catheters are passed to the heart through a vessel puncture. With them, the doctor identifies the areas of heart tissue involved in starting or sustaining the arrhythmia and applies radiofrequency energy to them. RFA is used for various rhythm disorders, including some types of tachycardia, atrial fibrillation and flutter, arrhythmias related to accessory pathways, and some types of extrasystole. An arrhythmologist determines the indications individually. RFA is performed at Pirogov Clinic in Saint Petersburg.

Radiofrequency ablation is a modern, minimally invasive method of restoring normal heart rhythm. Thin catheters are guided to the heart, and radiofrequency energy is applied precisely to the areas of heart tissue involved in starting or sustaining the arrhythmia.

If you have episodes of rapid heartbeat, irregular or skipped beats, see an arrhythmologist. They will identify the type of rhythm disorder and assess whether RFA could be an effective treatment in your case.

Which arrhythmias RFA treats

The technique is used for various rhythm disorders, including:

An arrhythmologist assesses individually whether RFA is possible and how effective it is likely to be.

Preparing for RFA: which tests are needed

To make an accurate diagnosis and determine indications for RFA, the following are performed:

  • ECG at rest and during exercise
  • 24-hour Holter monitoring
  • Echocardiography

An intracardiac electrophysiological study (EPS) may be performed before the ablation or during the procedure itself. It clarifies the mechanism of the arrhythmia and identifies the areas of the heart to be treated.

How radiofrequency ablation of the heart is performed

  1. Local anesthesia

    RFA is performed under local anesthesia, without incisions.

  2. Inserting the catheters

    Thin catheter electrodes are inserted through a small puncture in a vessel and guided to the heart under X-ray control.

  3. Mapping

    Depending on the type of arrhythmia, the doctor performs an electrophysiological study and mapping. When needed, 3D navigation systems are used to build an electroanatomical map of the heart and precisely identify the target areas.

  4. Ablation

    Radiofrequency energy is applied to the selected areas of heart tissue involved in starting or sustaining the arrhythmia.

The procedure is performed through a vessel puncture, without incisions, and aims to eliminate or suppress the mechanism of the arrhythmia.

Recovery after RFA and prognosis

  • The length of the hospital stay depends on the procedure and the patient’s condition. At our clinic it is usually 2–3 days
  • After discharge, most patients gradually return to normal activities within a few days. The physician sets the timing and restrictions individually
  • The physician decides whether to continue, change or later stop antiarrhythmic medication — do not stop treatment on your own
  • Follow-up visits to a cardiologist are usually at 3, 6 and 12 months

The effectiveness of RFA depends on the type and mechanism of the arrhythmia, how long it has lasted, other conditions and individual factors. For some types of tachycardia, catheter ablation eliminates the mechanism of the arrhythmia with high probability. For other rhythm disorders, atrial fibrillation in particular, recurrences are possible and a repeat procedure is sometimes needed. Like any invasive procedure, RFA carries certain risks. Their likelihood and nature depend on the type of procedure and the patient’s condition. The physician discusses possible complications with the patient beforehand.

The result depends not only on the operation but also on following medical advice: keep to it and see your cardiologist on time.

On October 8 of this year, 2026, I underwent radiofrequency ablation at the cardiac surgery department on Fontanka. This is a procedure that requires surgical precision, skilled and sensitive hands, sound judgment, and extensive experience. Cardiologist and arrhythmologist Evgeny Igorevich Zubarev performed this procedure brilliantly. I had prepared myself for a much more painful experience, as I was under local anesthesia, but everything turned out to be surprisingly tolerable and fairly quick — about 30 minutes. The hand of a true master! I am infinitely grateful to Dr. Evgeny Zubarev and the entire surgical team. May God grant them all good health and success in life, and may the Pirogov Clinic continue to prosper and thrive! – V.A. Malyagin

Review of the doctorYevgeny ZubarevArrhythmologist, Cardiac Surgeon

I came for a consultation with Anton Andreyevich back in August 2024, in Vologda. I was troubled by arrhythmia, and in the spring I had suffered a stroke. Doctor A. A. Sheremet offered me surgical treatment, explaining how important it is to start treatment in time. He calmly and clearly explained what RF ablation is and what result it would lead to. In October 2025 Anton Andreyevich performed the first RF ablation operation. Exactly one year later, on October 9, the operation to implant an occluder took place. I want to express huge gratitude to Anton Andreyevich and the entire surgical team for their high professionalism, well-coordinated teamwork, patience and attentive attitude towards patients. These are people devoted to their work. They give us a chance to return to normal life. I wish them good health, happiness, peace of mind, patience, and grateful patients. Success in your very difficult but so necessary work!

Review of the doctorAnton SheremetArrhythmologist, Cardiac Surgeon

I suffered from atrial fibrillation for many years and was on the waiting list for RFA. When I was admitted to the clinic, Anton Andreevich became my attending physician. I would like to express my sincere gratitude to the wonderful arrhythmologist and cardiac surgeon Anton Andreevich Sheremet. On April 1, 2026, he performed my RFA procedure. The procedure lasted 1.5 hours. Throughout that entire time, I felt that I was in the hands of a true professional — experienced and confident. At discharge, I received all the necessary consultations and answers to my questions. More than four months have now passed since the operation. The problems have not disappeared completely, but I feel noticeably better. Once again, many thanks to Anton Andreevich. I will recommend him as an excellent doctor. I would also like to express my sincere gratitude to his assistant, Umar Salambekovich, for his very attentive and kind attitude.

I would like to say a big thank you to Vera Valeryevna for her sensitive, competent, and genuinely caring attitude toward my problem. I suffered from arrhythmia for a long time and waited almost a year and a half for a government-funded quota for RFA surgery. Throughout that entire time, Vera Valeryevna continued to supervise my care, including consultations by phone. Many thanks to her. I definitely recommend consulting this specialist.

Review of the doctorVera PovarenkinaCardiologist

In May 2025, Anton Andreevich visited our city of Shakhty, and I had an appointment with him. A year later, at the end of May, I contacted the clinic and came on July 10 for an RFA procedure. The operation was also performed by Anton Andreevich. Anton Andreevich answered all the questions I had, so I felt calm. During the procedure, using their modern equipment, he also identified another diagnosis — atrial flutter. I will definitely recommend this clinic, and specifically Dr. Anton Sheremet. Many thanks to him once again! What I liked was the attitude of absolutely all the staff, from the cleaning personnel to the doctor.
