New treatment option for Atrial Fibrillation
Official title A Study of VARIPULSE Catheter in Participants With Persistent Atrial Fibrillation Undergoing Pulmonary Vein and Superior Vena Cava Isolation
ClinicalTrials.gov ID: NCT07527299
What this study is testing
- What it's testing
- The purpose of this study is to assess how safe VARIPULSE catheter system is for treatment of a heart rhythm disease called persistent atrial fibrillation (PsAF) in participants who are having a catheter ablation procedure (treat heart rhythm disease). This includes isolation of pulmonary vein and superior vena cava (heart veins; PVI and SVCI), with or without another technique called posterior wall isolation (PWI).
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
