Cardiology: Clinical Research Program

Inclusion Criteria 

• Is an adult male or female patient ≥ 18 years of age (or adult age as per country guidelines) and ≤ 85 years of age at the time of screening.
• Is able to understand and willing to comply with all trial procedures through the duration of planned follow-up, understand the risks involved in the trial, and provide written informed consent.
• Has a medical history supporting a diagnosis of clinical chronic HF syndrome with a duration of at least 8 weeks prior to the time of screening and current NYHA functional class II to III (based on investigator’s assessment).
• Has left ventricular EF ≤ 40% by a centrally read TTE performed during screening.
• Has NT-proBNP level ≥ 600 pg/mL (70.8 pmol/L) at the time of screening. Patients in atrial fibrillation or flutter at the time of screening are required to have an NT-proBNP level of ≥ 900 pg/mL (106.4 pmol/L).
• Is receiving optimized and stable guideline directed HF therapy (per applicable regional or national guidelines). Stable therapy is defined as having no new drug class introduced within 8 weeks prior to the time of screening or during screening (including intravenous iron replacement), and stable optimized doses for a minimum of 4 weeks prior to and during screening (excluding diuretics).

• Has a requirement for routine, scheduled outpatient IV infusions for HF (ie, inotropes, vasodilators, or diuretics) or routinely scheduled ultrafiltration. Repeat administration of IV iron replacement is allowed as clinically indicated per the investigator’s judgment but the initiation of IV iron replacement must be > 8 weeks prior to screening.

• Has electrolyte imbalances defined as serum potassium, albumin-corrected serum calcium, or serum magnesium levels below the lower limit of normal at screening.
• Has any elective invasive interventions (eg percutaneous coronary intervention, de novo device implantations, percutaneous structural heart disease interventions, or major cardiac or non-cardiac surgery) planned to occur during trial participation or has undergone this elective procedure within 8 weeks prior to screening, or during the Screening Period.
• Has acute coronary syndrome, unstable angina, persistent angina at rest, stroke, transient ischemic attack, cardiac, carotid or other major cardiovascular surgery, cardiac valve repair (surgical or nonsurgical) or surgical replacement, or carotid angioplasty within 8 weeks prior to screening or during the Screening Period.
• Has clinical suspicion of infiltrative cardiomyopathy (eg, amyloid, sarcoid), hypertrophic cardiomyopathy (obstructive or non-obstructive), or HF secondary to severe valvular disease, active myocarditis, active pericarditis, or clinically significant congenital heart disease.
• Has had a prior or planned orthotopic heart transplantation (being on a transplant list is acceptable as long as the investigator does not anticipate a transplant within the next year).
• Has presence of or plan for mechanical circulatory support.
• Has known bleeding diathesis.

Eligibility

• Subjects diagnosed with persistent (not longstanding) AF or recurrent AF, as defined for this study.
• Subject has a recent 12-lead electrogram data of AF (including baseline, pacing and clinical arrhythmia) recorded on the electrogram recording system (e.g., Bard, Boston-Scientific, St. Paul, MN or Prucka, GE Medical) or standalone ECG system (e.g., GE Muse, Minnesota, or CardioCard (Nasiff, NY) in digitized format.
• The following data elements can be abstracted from the patient medical records or confirmed and documented prior to the scheduled procedure (to be inputted in vMap®):
  • Atrial fibrillation type
  • Atrial characteristics: geometry (normal, left and/or right atrial enlargement), Utah classification, prior ablation modality (e.g., radiofrequency, cryoablation, pulsed field ablation), prior ablation lesion location(s).
• Subject is ≥ 22 years of age at time of enrollment/consent.
• Subject is indicated to undergo an ablation procedure at the medical discretion of the Investigator.
• Subject is able and willing to comply with the protocol requirements, has been informed of the nature of the study.
• Exclusion Criteria:
  • Subjects with arrhythmias other than persistent or recurring AF as defined for this study, including long-standing persistent atrial fibrillation (persistent AF lasting ≥ 1 year from diagnosis).
  • Inability to obtain ECG prior to or during the clinical ablation procedure; or unacceptable ECG data quality such as low ECG signal-to-noise ratio or lack of ECG data in one or more leads.
  • Subjects who are participating in another clinical investigation with an investigational drug or device at the time of enrollment or planned participation at any time during this clinical investigation.
  • Subjects who have a known or suspected medical condition that, in the opinion of the Investigator, may put the subject at risk for participation in this clinical investigation.
  • Subjects who are pregnant as confirmed by the institution’s standard pre-surgery practice.
