Previous studies have reported an association between impaired renal function and poor outcomes after radiofrequency catheter ablation in patients with atrial fibrillation (AF). However, outcomes of cryoballoon ablation (CBA) in patients with renal insufficiency are not fully elucidated. This study aimed to compare outcomes of CBA in AF patients with chronic kidney disease (CKD) versus those without CKD and to assess changes in renal function over 12 months following CBA.

心内超声心动图引导的无造影剂冷冻球囊消融治疗肾功能不全的房颤患者的临床结果。

先前的研究报告称，房颤（AF）患者的肾功能受损与射频导管消融术后不良结局之间存在关联。然而，肾功能不全患者的冷冻球囊消融（CBA）的结果尚未完全阐明。本研究旨在比较患有慢性肾脏病 (CKD) 的 AF 患者与无 CKD 的 AF 患者的 CBA 结局，并评估 CBA 后 12 个月内肾功能的变化。
