“We believe pulsed field ablation has the potential to offer safer, more consistent and efficient workflows, and the Varipulse Platform uniquely offers physicians a simple and reproducible PFA workflow with 3D visualisation, in real-time.”

Recently, Biosense received approval for the Varipulse platform in Japan.

Last month, Biosense Webster reported 12-month results from the inspIRE and admIRE trials, demonstrating month freedom from atrial arrhythmia recurrence in 80% of the patients with the use of the Varipulse platform.

The multicentre study of the treatment of PFA using Varipulse with irreversible electroporation (inspIRE trial – NCT04524364) enrolled patients with drug-refractory PAF.

From March 2021 to May 2022, the study was conducted across Canada and Europe. Of the 186 patients, 75.6% achieved the primary endpoint of acute pulmonary vein isolation and 12-month freedom from atrial arrhythmia recurrence.

Additionally, the study reported a fluoroscopy time of 7.8 minutes and a primary adverse event rate of 0.0%.
