NCT02131337

Brief Summary

EFFICAS II proposes to test the hypothesis that treatment efficacy correlates to contact force parameters applied for pulmonary vein isolation (PVI) during AF ablation.

Outcome Measures

Primary Outcomes (1)

  • Number of pulmonary vein isolation (PVI) gaps per vein

    Number of gaps in EFFICAS 2 is lower than in EFFICAS 1 and Contact force in EFFICAS 2 has reduced variability than in EFFICAS 1. Confounding parameters such as lesion continuity will be determined for the remaining gaps in EFFICAS 2.

    3 months

Study Arms (1)

Contact force lesions

Other: Electrophysiology study

You may qualify if:

  • Patient is at least 18 years of age but not over 75 years of age
  • Patient has at least one episode of sustained (\>30s) paroxysmal atrial fibrillation documented by 12-lead ECG, holter monitor, transtelephonic event monitor, telemetry strip, or Pacemaker respectively implantable cardioverter defibrillator (ICD) within 12 months prior to enrolment
  • Patient has symptomatic paroxysmal atrial fibrillation (PAF) refractory or intolerant to at least one Class I-IV anti-arrhythmic drug
  • Patient is willing and capable of complying with the study protocol requirements, including the specified follow-up scheme
  • Patient provides written informed consent prior to enrolment in the study

You may not qualify if:

  • Reversible causes of Arrhythmia including thyroid disorders, acute alcohol intoxication, recent (less than 3 months) major surgical procedures
  • Patient has a left atrial diameter \> 5.0 cm
  • Patient has persistent or long-standing persistent atrial fibrillation (AF)
  • Left ventricular ejection fraction \< 35%
  • New York Heart Association (NYHA) class III or IV
  • Previous left atrial heart ablation procedure, either surgical or catheter ablation
