Is this trial a fit for you?

Likely a good fit

Adults 18-80 with symptomatic paroxysmal AF refractory or intolerant to certain antiarrhythmic drugs, eligible for ablation, and able to comply with follow-up.

Probably not a fit

Patients with AF due to non-cardiac or reversible causes, prior left atrial procedures, large left atria, reduced LV function, or other exclusion criteria may not benefit from this approach.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to evaluate long-term outcomes of the Varipulse Catheter ablation procedure in adults with symptomatic paroxysmal atrial fibrillation who have not had adequate relief with antiarrhythmic drugs or cannot tolerate them, across varied anesthesia types. Participants will be adults ages 18 to 80 and must meet pre- and post-procedure testing and follow-up requirements with informed consent. The trial excludes AF caused by reversible conditions, prior left atrial surgery or ablation, larger left atrial size, reduced ejection fraction, certain PV anomalies, concurrent investigational therapies, and pregnancy. Lead sponsor is Johnson & Johnson Medical (Shanghai) with the study site at Zhongshan Hospital Fudan University in Shanghai, China.

Why it matters

Potential benefit: If successful, patients may experience better long-term rhythm control with safer or more comfortable anesthesia options during the ablation procedure.

How similar studies have gone: Previous ablation approaches using similar devices have shown promise in select AF populations, but this specific comparison with sedation types is exploratory.

* Signed patient informed consent form (ICF)

Exclusion criteria:

* Atrial fibrillation (AF) secondary to electrolyte imbalance, hyperthyroidism, or reversible or non-cardiac cause
* Previous left atrium (LA) ablation or surgery
* Left atrium diameter (LAD) greater than (\>) 50 millimeters (mm) by transthoracic echocardiography (TTE)
