High-Density (HD) Wave Mapping in Subjects With Atrial Fibrillation as a Predictor of Recurrence After a Single Ablation Procedure Using a PVI-Only Strategy

High-Density (HD) Wave Mapping in Subjects With Atrial Fibrillation as a Predictor of Recurrence After a Single Ablation Procedure Using a PVI-Only Strategy

The aim is to use the Advisor™ HD Grid Mapping Catheter, Sensor Enabled™ to characterize the atrial substrate and develop a model for predicting recurrence rates after a single procedure using a PVI only approach and a contact catheter.

This clinical investigation is intended to characterize the left atrial substrate using the Advisor™ HD Grid Mapping Catheter, Sensor Enabled™ in an HD Wave configuration and correlate different factors with 12-month success after a single ablation procedure using a pulmonary vein isolation (PVI) approach without further substrate modification.

This is a post-market, single-arm, multi-center, prospective interventional study of the Advisor™ HD Grid Mapping Catheter, Sensor Enabled™. This study is aimed at determining correlations between pre-ablation mapping characteristics and outcomes after catheter ablation of atrial fibrillation.

Approximately 300 subjects at up to 20 sites worldwide will be enrolled.

Subjects will be followed until they complete their 12-month visit. Clinical Investigation visits will occur at Baseline (confirmation of eligibility), Index Procedure, 3 months, 6 months, and 12 months. Endpoints will be analyzed when all subjects have completed their 12-month follow up visits.

Inclusion Criteria:

1. Documented atrial fibrillation with planned endocardial ablation procedure
2. Age 18 years or older
3. Able and willing to provide written informed consent prior to any clinical investigation related procedure
4. Able and willing to complete all required study procedures through 12 months

Exclusion Criteria:

1. Long-standing persistent atrial fibrillation defined as continuous AF greater than 12 months in duration
2. Previous ablation or surgery in the left atria
3. Implanted left atrial appendage occluder
4. Implanted mitral or tricuspid valve replacement
5. Implanted cardiac defibrillator (ICD)
6. Participation in another clinical investigation that may confound the results of this study
7. Pregnant or nursing
8. Presence of other anatomic or comorbid conditions, or other medical, social, or psychological conditions that, in the investigator's opinion, could limit the subject's ability to participate in the clinical investigation or to comply with follow-up requirements, or impact the scientific soundness of the clinical investigation results.
9. Life expectancy less than 12 months
