Boston Scientific Corp. recently reported new four-year data on its Farapulse pulsed field ablation platform, which demonstrated that patients with paroxysmal atrial fibrillation achieved better long-term success than those treated with thermal ablation. The data come as sales of the Farapulse system in the U.S. have begun to slow amid rising competition from other PFA technologies, particularly Medtronic plc’s Affera platform.
