CAAP-AF Score (Freedom From AF After Ablation)
CAAP-AF score (Winkle 2016): coronary disease, left-atrial diameter, age, persistent AF, number of failed antiarrhythmic drugs, and female sex give a 0–13 score; a higher score marks lower freedom from AF after ablation.

Example
- Left-atrial diameter
- 4.2 cm
- Age
- 72 years
- Number of failed antiarrhythmic drugs
- 1
- Coronary artery disease
- Yes
- Persistent / long-standing persistent AF
- No
- Female sex
- Yes
Result: CAAP-AF 7 — elevated recurrence risk (>= 5).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- < 5
- Higher freedom from AF after ablation.
- >= 5
- Elevated AF recurrence. CAD, LA-diameter band, age band, persistent AF (+2), failed-AAD band, female. A recurrence-risk score, not an ablation order.
What you enter
- Left-atrial diameter
- Age
- Number of failed antiarrhythmic drugs
- Coronary artery disease (+1)
- Persistent / long-standing persistent AF (+2)
- Female sex (+1)
