MB-LATER Score (Very-Late AF Recurrence)
MB-LATER score (Mujović 2017): male sex, bundle-branch block, large left atrium, AF type (0 paroxysmal / 1 persistent / 2 long-standing), and early recurrence give a 0–6 score.

Example
- AF type
- 1
- Male sex
- Yes
- Bundle-branch block
- No
- Left atrium ≥ 47 mm
- Yes
- Early AF recurrence within 3 months
- No
Result: MB-LATER 3 — elevated very-late recurrence risk (>= 2).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- < 2
- Lower very-late (> 12 mo) AF recurrence after ablation.
- >= 2
- Elevated very-late recurrence. Male, bundle-branch block, LA >= 47 mm, AF type (0-2), early recurrence < 3 mo. Not an ablation order.
What you enter
- AF type (0 = paroxysmal, 1 = persistent, 2 = long-standing persistent)
- Male sex (+1)
- Bundle-branch block (+1)
- Left atrium ≥ 47 mm (+1)
- Early AF recurrence within 3 months (+1)
