Treatment: Devices - Advisor HD Grid Mapping Catheter, Sensor Enabled

Treatment: Devices: Advisor HD Grid Mapping Catheter, Sensor Enabled
The Advisor™ HD Grid Mapping Catheter, Sensor Enabled™, is indicated for multiple electrode electrophysiological mapping of cardiac structures in the heart, i.e., recording or stimulation only. This catheter is intended to obtain electrograms in the atrial and ventricular regions of the heart.

Key exclusion criteria
1. Life expectancy less than 12 months
2. Women who are pregnant or nursing
3. Known intracardiac thrombus or myxoma verified within 48 hours of index ablation procedure
4. Myocardial infarction (MI) or unstable angina, or previous cardiac surgery within 60 days of index ablation procedure
5. Percutaneous coronary intervention (PCI) within 30 days of index ablation procedure
6. Documented cerebro-embolic event within the past 12 months (365 days)
7. History of valve repair, presence of a prosthetic valve, or severe mitral regurgitation thought to require valve replacement or repair within 12 months
8. Awaiting cardiac transplantation or other cardiac surgery within the next 12 months (365 days)
9. Current acute illness or active systemic infection or sepsis
10. Currently enrolled in another clinical study that could confound the results of this study
11. Any cause for contraindication to ablation procedure or systemic anticoagulation
12. 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 study or to comply with follow-up requirements, or impact the scientific soundness of the clinical study results.
13. Vulnerable patient or individuals whose willingness to volunteer in a study, in the judgement of investigator or public authorities, could be unduly influenced by lack of or loss of autonomy
14. Indication-specific exclusion criteria including:
