A substantial proportion of patients undergoing elective coronary artery bypass grafting have a history of paroxysmal atrial fibrillation. Paroxysmal atrial fibrillation has adverse short-and long term postoperative effects. Pulmonary vein isolation (PVI) seems to be effective treatment for paroxysmal atrial fibrillation. PVI can be done concomitantly with coronary artery bypass grafting. Procedure is well defined and safe.

There is a lack of convincing evidence of the effect on postoperative atrial fibrillation burden, quality of life and symptoms especially in correlation with atrial fibrillation paroxysms.

Further study details as provided by Kuopio University Hospital:

Primary Outcome Measures:
  • Atrial fibrillation burden [ Time Frame: Within one year after operative treatment ] [ Designated as safety issue: No ]
    Atrial fibrillation burden is defined as the amount of atrial fibrillation on one week Holter monitoring

  • Freedom of symptomatic and asymptomatic atrial fibrillation after surgery [ Time Frame: Within one year after operative treatment ] [ Designated as safety issue: No ]

    Atrial fibrillation is defined as atrial fibrillation paroxysm lasting at least 60 seconds.

    Freedom of atrial fibrillation is defined as duration of atrial fibrillation less than 0,5% of the one week Holter monitoring

Secondary Outcome Measures:
  • Compare quality of life (QOL) and symptoms, correlation of symptoms with atrial fibrillation [ Time Frame: Within one year after operative treatment ] [ Designated as safety issue: No ]
  • Adverse events after surgery in both arms [ Time Frame: Within one year after operative treatment ] [ Designated as safety issue: No ]
  • Anti-arrhythmic treatment after surgery [ Time Frame: Within one year after treatment ] [ Designated as safety issue: No ]
  • Hospitalization due to atrial fibrillation after surgery [ Time Frame: Within one year after operative treatment ] [ Designated as safety issue: No ]
  • Cardioversion for the treatment of atrial fibrillation after surgery [ Time Frame: Within one year after operative treatment ] [ Designated as safety issue: No ]
  • Other cardiovascular related events: death, stroke, cardiac infarction, need for revascularization and bleeding [ Time Frame: Within one year after operative treatment ] [ Designated as safety issue: No ]
