Abstract

Background: Recent data has suggested atrial fibrillation (AF) ablation was associated with unexpectedly increased early mortality (within 30 days) from national readmission data sets.
Objective: Our study is to provide an updated analysis using 2016 national readmission database based on current ICD codes.
Methods: Patients were identified using ICD-10 disease and procedure code. Early mortality were defined as death within 30 days of procedure either from index admission or readmission. Complications were defined as per Agency for Health Care Research and Quality guideline. Statistical tests including multivariate regression analysis were performed.
Results: Among 19, 493 procedures performed in 2016, there were 298 (1.5%) early mortality (69 of whom died during readmission, 20% due to sepsis). Patients who succumbed to early mortality from procedure were older patient with higher percentage of female, higher comorbidity burden (Chalson Comorbidity Index and CHADVASC score) and higher complication rate (Table 1). Notably more than half of the death were within 15 days of the procedure (Figure 1). Predictors of early mortality were age, Chalson Comorbidity Index, any procedure complication and chronic AF status. Procedure volume were associated with less early mortality (Table 2).
Conclusion: Based on our data AF ablation is associated with early mortality of 1.5%. Predictors of early mortality are age, comorbidity burden, procedure complication, lower procedure volume, and chronic AF status
