In clinical trial results, Boston Scientific's Farapulse system demonstrates equivalent effectiveness to Medtronic's cryoablation system for treating atrial fibrillation.
Boston Scientific's Farapulse PFA Catheter Shows Promise in Treating Paroxysmal Atrial Fibrillation
Recent clinical trial data have shown that Boston Scientific's Farapulse Pulsed Field Ablation (PFA) catheter is noninferior in effectiveness to Medtronic's Arctic Front cryoballoon for treating paroxysmal atrial fibrillation (PAF). This means that Farapulse PFA demonstrated comparable efficacy to the Arctic Front cryoballoon in clinical outcomes for PAF patients.
The study, published in The New England Journal of Medicine, randomized 210 patients with symptomatic paroxysmal atrial fibrillation to undergo pulsed field ablation (PFA) or cryoablation. The study found that PFA was noninferior to conventional therapy on a composite endpoint that looked at one-year outcomes including atrial tachyarrhythmia after a three-month period. No PFA patients in the Swiss trial had energy-related complications such as pulmonary vein stenosis, persistent phrenic nerve palsy or atrioesophageal fistula.
Atrial tachyarrhythmia, a heart rhythm disorder, recurred in 39 patients in the PFA cohort and 53 people in the cryoablation group. The researchers saw recurrences in 37.1% of the PFA patients and 50.7% of the cryoablation patients through day 365, achieving the study's primary noninferiority endpoint. However, the superiority test was "formally positive," but because the result "reached only borderline statistical significance," larger outcome trials are needed to show whether PFA is superior to cryoablation.
Meanwhile, Medtronic reported declines in its cryoablation business in the first and second quarters of its 2025 financial year. However, Geoff Martha, CEO of Medtronic, stated that PFA growth more than offset these declines. Martha framed the shift from cryoablation to PFA as a net positive, as Medtronic's PFA devices have enabled the company to enter "big, high-volume centers." Martha also predicted strong growth for Medtronic in PFA devices.
On the other hand, Boston Scientific has claimed leadership in the PFA market. The authors of the new NEJM paper said that previous PFA studies "lacked continuous rhythm monitoring." In the Swiss hospital study, all patients received Medtronic's Reveal Linq, an implantable cardiac monitor, for continuous rhythm monitoring.
Ricky Zipp wrote an article titled "Boston Scientific closes its year of PFA on a high note," highlighting the company's success in the PFA market. The study comparing Boston Scientific's pulsed field ablation catheter, Farapulse, with Medtronic's Arctic Front cryoballoon was presented at major electrophysiology forums (e.g., EHRA 2025).
In conclusion, the latest clinical trial evidence supports that Boston Scientific's Farapulse PFA catheter is as effective as Medtronic's Arctic Front cryoballoon in treating paroxysmal atrial fibrillation, positioning it as a viable alternative in the arrhythmia ablation landscape. Larger outcome trials are needed to determine whether PFA is superior to cryoablation, but the shift towards PFA technology is already underway.
