A Study of Varipulse Catheter in Participants With Paroxysmal Atrial Fibrillation Under Optimized Sedation

Not Yet RecruitingN/A

Sponsor: Johnson & Johnson Medical (Shanghai) Ltd.

Conditions: Atrial Fibrillation

The main purpose of the study is to assess how well the standard ablation procedure (Varipulse Catheter) works over long term when used with different types of anesthesia in participants with symptomatic paroxysmal atrial fibrillation (PAF, irregular heartbeat that comes and goes on its own, causing noticeable symptoms like a racing heart, or shortness of breath).

Eligibility overview

Sex: ALL

Age: 18 Years to 80 Years

Healthy volunteers: No

Study type: OBSERVATIONAL

Eligibility criteria

* Previous left atrium (LA) ablation or surgery
* Left atrium diameter (LAD) greater than (\>) 50 millimeters (mm) by transthoracic echocardiography (TTE)
* Left ventricular ejection fraction (LVEF) less than (\<) 40 percent (%)
* Known significant pulmonary vein (PV) anomaly that in the opinion of the investigator would preclude enrollment in this study
