A Study of VARIPULSE Catheter and TRUPULSE Generator With VARIPULSE Pro Software in Participants With PAF or PsAF

Официальное название

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

Обзор

The main purpose of this clinical study is to investigate the effectiveness 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 paroxysmal atrial fibrillation (PAF; irregular heartbeat where episodes start and stop on their own, usually within seven days) and persistent atrial fibrillation (PsAF; irregular, rapid heartbeat that lasts over 7 days up to 1year and doesn't stop on its own).
