Egyéb

• 18 to 75 years of age
• Symptomatic Paroxysmal AF.
  • Symptomatic paroxysmal AF is defined by AF with patient-reported perception of one or more of the following symptoms: palpitations, dizziness/presyncope, syncope, dyspnea, chest pain, malaise, and fatigue and activity intolerance.
  • There is at least one ECG-documented AF episode.
• Unresponsive to conventional therapy is defined by not responding to at least 1 antiarrhythmic drug (class I, class III, or atrioventricular nodal blocker).
• The left atrial size \<50 mm by transthoracic echocardiography documented by eligibility visit echocardiogram
• Documented atrial fibrillation as defined as atrial fibrillation \>30 seconds in duration with an atrial fibrillation burden determined by a minimum of 7 days of continuous ePatch monitoring within 6 months before surgery.
