Postoperative Atrial Arrhythmias After Lung Transplantation: A Single Center Analysis of Risk Factors, Management, and Outcomes

POAA was common and clinically significant after lung transplant, associated with substantially higher adjusted mortality even when occurring after index hospitalization. We report for the first time that POAA was frequently associated with emergency visits or rehospitalization for arrhythmia, highlighting its clinical burden well beyond the perioperative period. Postoperative beta-blocker use was associated with markedly less POAA, a novel finding suggesting a potential prophylactic role. Overall, these findings challenge the traditional view of POAA as benign and highlight the need for tailored, evidence-based guidelines in this high-risk population.
