Brief Summary:
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia. Current European guidelines recommend catheter ablation of AF in symptomatic patients refractory to antiarrhythmic therapy. Pulmonary vein isolation (PVI) remains the cornerstone of any ablation procedure irrespective of patient characteristics. Recently, stereotactic arrhythmia radioablation (STAR) with precise high-dose of radiation was used to treat ventricular arrhythmias in patients with a high risk of complications during transcatheter ablation.

Condition or disease Intervention/treatment Phase
Atrial Fibrillation Radiation: STAR Treatment Not Applicable

Detailed Description:
Exploratory study to investigate the feasibility of STAR for the treatment of paroxysmal AF in elderly patients in which a rhythm control strategy is indicated. Patients will be followed-up for 12 months after STAR treatment for a safety assessment and AF recurrence.

Arm Intervention/treatment
Experimental: STAR Treatment
Patients performing STAR treatment
Radiation: STAR Treatment
Radiation therapy that delivers non-invasive, image-guided, precise high-dose of radiation to targets reducing dose exposure to adjacent normal tissue and minimizing the treatment toxicity.

Primary Outcome Measures :
  1. Incidence of Adverse Events related to STAR treatment [ Time Frame: Baseline through 12-months ]
    To estimate the cumulative proportion of patients' Adverse Events related to STAR treatment

Secondary Outcome Measures :
  1. Incidence of AF recurrence [ Time Frame: Baseline through 12-months ]
    To estimate the proportion of patients with AF

  2. Long-term clinical outcomes [ Time Frame: Baseline through 10-years ]
    To estimate the cumulative proportion of all-cause death, cardiovascular death, stroke, heart failure hospitalization, AF recurrence, cancer occurrence
