About this trial

The purpose of the trial is to find out if the Grid X Mapping Catheter and EnSite X EP System with EnSite X Software v3.1.1, the devices that are being studied, are safe and effective in treating Chinese patients who have atrial fibrillation.

Participants will receive a procedure called catheter mapping and ablation to treat their abnormal heart rhythms and are required to complete 4 follow-up visits at 7 days, 3 months, 6 months and 12 months after the procedure for checkups and tests.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Subject must provide written informed consent prior to any clinical investigation-related procedure.

Subject is at least 18 years of age.

Physician's note indicating self-terminating AF AND

Electrocardiographically documented AF NOTE: Documented evidence of the AF episode must either be continuous AF on a 12-lead ECG or include at least 30 seconds of AF from another ECG device.

Disqualifiers

Primary diagnosis or indication for treatment of persistent or long-standing persistent atrial fibrillation (Continuous AF greater than 1 year in duration)

Known presence of cardiac thrombus.

Known existing circumferential pericardial effusion >2 mm prior to catheter insertion.

Presence of any condition that precludes appropriate vascular access

Trial outcomes

Primary outcomes

1

Rate of specified device and/or procedure-related serious adverse events

Safety will be summarized as the rate of subjects experiencing a device and/or procedure-related serious adverse event with onset prior to subject discharge from the hospital after any study procedure that used the Grid X mapping catheter and EnSite X EP System (v3.1.1), as defined below: * Esophageal perforating complications * Cardiac tamponade/perforation * Death * Heart block * Myocardial infarction * Pericarditis * Phrenic nerve injury resulting in diaphragmatic paralysis * Pulmonary edema * Pulmonary vein stenosis * Stroke/cerebrovascular accident * Thromboembolism * Transient ischemic attack * Vagal nerve injury/gastroparesis * Major vascular access complications / major bleeding event * Device and/or procedure related cardiovascular and/or pulmonary adverse event that prolongs hospitalization for more than 48 hours (excluding hospitalization solely for arrhythmia recurrence or non-urgent cardioversion)

Time frame
From the study procedure to subject's discharge from the hospital
2

Proportion of subjects with ablation targets identified by HD Grid X catheter

The primary effectiveness endpoint will be defined as the proportion of subjects in which ablation targets were able to be defined or identified by HD mapping using the Grid X catheter. The definitions of ablation targets include, but are not limited to: * Reconnected pulmonary veins * Low voltage zones * Slow conduction sites * Focal arrhythmias * Complex fractionated electrograms * Areas of fibrosis/scar
