Treatment of PAF With the Synaptic System

Korábbi kezelés

• History of previous left atrial ablation or surgical treatment for AF/AFL/AT
• History of documented cerebral infarct, TIA or systemic embolism,excluding post-operative deep vein thrombosis (DVT) ≤ 180 days prior to enrollment

Más betegség

• Atrial fibrillation secondary to electrolyte imbalance, thyroid disease, or any other reversible or non-cardiac cause
• History of cryoglobulinemia
• Significant untreated restrictive or obstructive pulmonary disease or chronic respiratory condition
• Renal failure requiring dialysis
• History of blood clotting or bleeding disease
• Active systemic infection
• Any other condition that, in the judgment of the Investigator, makes the patient a poor candidate for this procedure, the study or compliance with the protocol (includes, but not limited to, vulnerable patient population, mental illness, Gastroesophageal Reflux Disease (GERD), addictive disease, terminal illness with a life expectancy of less than two (2) years, or extensive travel away from the research center)

Laborértékek

  • Implanted pacemaker, ICD, CRT device within 90 days prior to enrollment
  • Previous cardiac surgery, ventriculotomy, or atriotomy (excluding atriotomy for CABG)
  • Previous cardiac valvular surgical or percutaneous procedure, or prosthetic valve, including mitral valve clips
  • Interatrial baffle, closure device, patch, or patent foramen ovale (PFO) occluder
  • Presence of a left atrial appendage occlusion device
  • Presence of any pulmonary vein stents
  • Coronary artery bypass graft (CABG), PTCA, PCI, or coronary stent procedures within 90 days prior to enrollment
  • Unstable angina or ongoing myocardial ischemia
  • ST-Elevation Myocardial Infarction (STEMI) within 90 days prior to enrollment

Egyéb

• Diagnosis of persistent AF, i.e., continuous AF lasting longer than seven (7) days from onset
• In the opinion of the Investigator, any known contraindication to an atrial ablation or anticoagulation. Including but not limited to the identification of any atrial thrombus or evidence of sepsis

  • A physician's note indicating recurrent atrial fibrillation (AF) which includes at least two (2) symptomatic AF episodes within six (6) months prior to enrollment; AND
  • One electrocardiographically (from any form of rhythm monitoring, including consumer devices) documented AF episode within 12 months prior to enrollment.
• Refractory or intolerant to at least one (1) Class I or III anti-arrhythmic medication or contraindicated to any class I or III medication.
• Suitable candidate for catheter ablation.
• Adults aged 18 - 80 years.
• Willing and able to comply with all baseline and follow-up evaluations for the full length of the study.
• Willing and able to provide informed consent.
