Surgical Ablation for Atrial Fibrillation: Risk Factors for Recurrence and Long-Term Outcome
Authors' conclusion
Surgical ablation had a high success rate, with freedom from recurrent atrial arrhythmia at 1-, 3-, 5-, and 7-year follow-ups. Age and female sex were factors determining the 5- and 7-year recurrence of AF.
Study context

- Patients undergoing concomitant or stand-alone surgical atrial fibrillation (AF) ablation, Israel's largest university tertiary care center, 2006–2022
- Participants
- 668 patients
- Outcome
- Freedom from AF and mortality
Methodological detailsprospectively collected data, single-centre
- Prospectively collected data
- Single-centre
Main finding
As reported in the abstract

- 97.6%
- Mortality at 1 year (n = 20)
- 3%
- Freedom from AF at 3 years (n = 574)
- 95.3%
- Mortality at 3 years (n = 45)
- 6.1%
- Freedom from AF at 5 years (n = 396)
- 90.1%
- Mortality at 5 years (n = 61)
- 9.1%
- Freedom from AF at 7 years (n = 308)
- 77.5%
- Mortality at 7 years (n = 72)
- 10.8%
Observational data: associations, not effects.
Further findings
Risk factors for 7-year freedom from AF and 7-year mortality (logistic regression)
- Age and female sex determined 7-year freedom from AF
- Risk factors for 7-year mortality: DM, age, valve surgery
