Task: Answer Verification
Input (English): Question: Is impaired renal function associated with recurrence after cryoballoon catheter ablation for paroxysmal atrial fibrillation : A potential effect of non-pulmonary vein foci?
Answer: Low eGFR at baseline was an independent predictor of recurrence after cryoballoon ablation for paroxysmal AF. The presence of non-PV ectopic beats was significantly increased in patients with impaired renal function, which might be associated with a poor outcome.
Output (English): yes
