Outcome Measures

Primary Outcomes (1)

  • 90 days adverse events by CTCA5

    Safety will be assessed by incidence and evaluation of any adverse events using CTCA5 V5.0 criteria that are related to the procedure

    90 days

Secondary Outcomes (5)

  • 12 months adverse events by CTCA5

    12 months

  • Recurrence of atrial fibrillation after 90 days blanking period post-treatment

    90 days

  • Atrial fibrillation burden reduction after 90 days blanking period post-treatment

    90 days to 12 months

  • Cardiovascular Mortality

    12 months

  • All-Cause Mortality

    12 months

Study Arms (1)

Stereotactic Radioablation

EXPERIMENTAL

Noninvasive Stereotactic Radioablation will be delivered in a single fraction to electrical isolate the pulmonary veins under CT-guidance. Pulmonary vein isolation will be assessed by using Cardioinsight non-invasive mapping system

Radiation: Stereotactic Radioablation

Interventions

Stereotactic Radioablation targets on the pulmonary vein ostium aiming to achieve PVI

Stereotactic Radioablation

  • Awaiting cardiac transplantation or other cardiac surgery within the next year
  • Myocardial infarction (MI) within 60 days prior to enrolment
  • Contraindications to oral anticoagulation
  • Active systemic infection or sepsis
  • History of a documented thromboembolic event such as stroke or transient ischemic neurological attack (TIA) in the three months prior to enrollment.
  • Any other clinical condition that might jeopardize patient safety during participation in this trial or prevent the subject from adhering to the trialprotocol
