Knowledge of the impact of paroxysmal and persistent atrial fibrillation (AF) after catheter ablation on in-hospital outcomes and 30-day readmission remains limited.This study aimed to evaluate the procedural outcomes and 30-day readmission rates among patients with paroxysmal or persistent AF who were hospitalized for AF ablation.Using the Nationwide Readmissions Database, our study included patients aged ≥18 years with AF who were hospitalized and underwent catheter ablation during 2017-2020.Then, we compared the in-hospital procedural outcomes and 30-day readmission rates between patients with paroxysmal and persistent AF, respectively.Our study included 7310 index admissions for paroxysmal AF ablation and 9179 index admissions for persistent AF ablation.According to our analysis, there was no significant difference in procedural complications-namely, cerebrovascular accident, vascular complications, major bleeding requiring blood transfusion, phrenic nerve palsy, pericardial complications, and systemic embolization-between the persistent and paroxysmal AF groups.There was also no significant difference in early mortality between these groups (0.5% vs. 0.7%; P = .22).Persistent AF patients had significantly higher rates of prolonged index hospitalization (9.9% vs. 7.2%; P < .01)and non-home discharge (4.8% vs. 3.1%; P < .01).The 30-day readmission rates were comparable in both groups (10.0% vs. 9.5%; P = .34),with recurrent AF and heart failure being two of the most common causes of cardiac-related readmissions.Catheter ablation among hospitalized patients with paroxysmal or persistent AF resulted in no significant difference in procedural complications, early mortality, or 30-day readmission.This suggests that catheter ablation of AF can be performed with a relatively similar safety profile for both paroxysmal and persistent AF.
