Pulsed field ablation (PFA) is a newer approach that uses electrical pulses to treat the heart tissue responsible for abnormal rhythms.
What is pulsed field ablation for atrial fibrillation? Pulsed field ablation is a catheter-based treatment that uses brief, high-energy electrical pulses to create small areas of targeted tissue injury. Unlike conventional thermal ablation, which uses heat or cold, PFA relies on a process called electroporation. It is designed to affect heart muscle cells while reducing injury to nearby structures, such as the oesophagus and phrenic nerve.
Who can benefit from pulsed field ablation for AFib? PFA may be suitable for people with symptomatic atrial fibrillation, particularly when antiarrhythmic medicines are ineffective, cause side effects or are not preferred.
It may be used for selected patients with paroxysmal AFib, which comes and goes, or persistent AFib.Suitability depends on the type of arrhythmia, heart health, medical history and individual risk factors. A cardiologist specialising in heart rhythm disorders can assess whether ablation is appropriate.
How does pulsed field ablation treat atrial fibrillation? During the procedure, a doctor guides a catheter through a blood vessel, usually from the groin, to the heart. Electrical pulses are delivered around the openings of the pulmonary veins, where many AFib-triggering signals originate. This creates a ring of treated tissue that helps block abnormal electrical signals from reaching the heart’s upper chambers. The procedure is performed in a hospital, typically with sedation or general anaesthesia, and the team monitors the heart throughout.
Is pulsed field ablation safe for atrial fibrillation? PFA has shown a favourable safety profile in clinical studies, with a lower risk of certain complications associated with thermal ablation. However, it is not risk-free. Possible complications include bleeding or damage at the catheter entry site, blood vessel injury, fluid around the heart, ischaemic attack and, rarely, other serious events. The treating team will explain the benefits and risks based on the patient’s condition. Consulting the Best Cardiologist in Chennai with expertise in cardiac electrophysiology can help patients understand their treatment options.
How long does it take to recover after pulsed field ablation? Many patients go home the same day or after an overnight stay, depending on their condition and hospital protocol.
They may need to rest and avoid strenuous activity for several days while the catheter entry site heals. Mild tiredness or brief palpitations can occur during recovery. Follow-up appointments and prescribed medicines, including blood thinners when indicated, remain important.
