Depiction of the propensity score matched analysis of acute kidney injury. Patients with atrial fibrillation were stratified based on ablation decision at the time of surgery (concomitant Cox-Maze IV vs no AF ablation). Concomitant CMP-IV was associated with increased risk of AKI in the acute postoperative period (P<0.001), which was counterbalanced by prolonged late survival due to restoration of sinus rhythm.
AF, atrial fibrillation; AKI, acute kidney injury; CMP-IV, Cox-Maze IV.
