About

This prospective, randomized, controlled, unblinded, multicenter study aims at comparing procedural time between conventional CLOSE-guided pulmonary vein isolation (PVI) (35W/50W) versus very high power radiofrequency delivery (90W) in atrial fibrillation patients scheduled for a first PVI.

Enrollment

182 patients

Sex

All

Ages

18+ years old

Volunteers

No Healthy Volunteers

Inclusion criteria

  • Patients older than 18 years
  • Patients scheduled for a first PVI only for paroxysmal atrial fibrillation (AF) (self-terminating or <7days) or persistent AF (persistent AF is defined as having an AF episode >7d); (patients with paroxysmal AF or short-standing persistent AF presenting with flutter, who are in need of a cavotricuspid isthmus ablation, are allowed to participate in this trial)
  • Patients willing to sign informed consent

Exclusion criteria

  • Patients with long-standing persistent AF (long-standing persistent AF is defined as having an AF episode >1yr)
  • Previous ablation for AF
  • Left atrium antero-posterior diameter >50 mm (parasternal long axis view, PLAX)
  • AF secondary to electrolyte imbalance, thyroid disease, or reversible or non-cardiac cause
  • Left atrial appendage (LAA) thrombus. LAA thrombus can be determined by preprocedural imaging: CT, transesophageal echocardiography or MRI.
  • Left ventricular ejection fraction <35%.
  • Cardiac surgery within the previous 90 days.
  • Expecting cardiac transplantation or other cardiac surgery within 180 days.
  • Coronary percutaneous transluminal coronary angioplasty/stenting within the previous 90 days or myocardial infarction within the previous 60 days.
  • Documented history of a thromboembolic event within the previous 90 days.
  • Diagnosed atrial myxoma.
  • Significant restrictive, constrictive, or chronic obstructive pulmonary disease with chronic symptoms.
  • Significant congenital anomaly or medical problem that in the opinion of the investigator would preclude enrollment
  • Women who are pregnant or who plan to become pregnant during the study.
  • Acute illness or active infection at time of index procedure
  • Advanced renal insufficiency
  • Unstable angina.
  • History of blood clotting or bleeding abnormalities.
  • Contraindication to anticoagulation.
  • Life expectancy less than 1 year.
  • Presence of a condition that precludes vascular access.
  • Unwilling or unable to provide informed consent.
