Why the study?
Do CHADS2, R2CHADS2, and CHA2DS2-VASc scores predict rhythm outcomes after catheter ablation of atrial fibrillation?
Do CHADS2, R2CHADS2, and CHA2DS2-VASc scores predict rhythm outcomes after catheter ablation of atrial fibrillation?
While R2CHADS2 and CHA2DS2-VASc scores are associated with rhythm outcomes after AF ablation, new clinical scores should incorporate AF type, left atrial diameter, and early recurrence of AF to improve prediction.
R2CHADS2 and CHA2DS2-VASc may inform post-ablation rhythm risk but remain incomplete; leaves open whether adding AF type, diameter, and ERAF improves scores.
R2CHADS2 and CHA2DS2-VASc were associated with rhythm outcomes after catheter ablation. However, AF type, left atrial diameter, and especially ERAF are also significant predictors for LRAF that should be included into new clinical scores for the prediction of rhythm outcomes after catheter ablation.
