Authors' conclusion

In adults below 30 years, catheter ablation for atrial fibrillation delivers high rhythm control with low complication rates. Benefit is lower in persistent than paroxysmal atrial fibrillation. Atrial fibrillation subtype is the strongest determinant which may argue for early referral to ablation as first-line rhythm control in young adults.
