A Study of VARIPULSE Catheter and TRUPULSE Generator With VARIPULSE PRO Software in Participants With PsAF

Официальное название

Workflow Study of the VARIPULSE™ Catheter With the TRUPULSE™ Generator for Treatment of Persistent Atrial Fibrillation (PsAF) With the New VARIPULSE™ Pro Software

Обзор

The main purpose of this study is to investigate the workflow of the clinical use of the pulsed field (PF) ablation system (VARIPULSE catheter and TRUPULSE generator) when used for cardiac ablation with the new VARIPULSE Pro software in participants with persistent atrial fibrillation (PsAF; irregular, rapid heart rhythm that lasts over 7 days and doesn't stop on its own)
