Introduction: Radiofrequency ablation is the first-line treatment for recurrent tachyarrhythmias. Patients undergoing cardiac ablations are understandably at higher risk of bleeding given arrhythmias and ongoing anticoagulation. Gastrointestinal bleeding is an a known complication of the procedure which leads to prolonged length of hospital stay, increased odds of ICU admission, and increased readmission rate.

Methods: The Nationwide Readmissions Database 2016-2020 was used to identify patients admitted with index All-cause cardiac


ablation



admission. Patients were stratified based on procedures complicated by GI hemorrhage. Multivariate analysis of predictors of 180-day readmission was performed.

Results: 0.94% (n=3,347) of all-cause cardiac ablation (n=339,871) procedures were complicated by gastrointestinal hemorrhage. All-cause cardiac ablation with GI hemorrhage group were older 72(IQR66-78) vs 68(IQR60-75) years, had longer LOS 6(IQR3-11) vs 5(IQR2-8) days, greater total charge $164,930(IQR 105,338-251,751) vs $153,471(IQR 101,328-235,471) than cardiac ablation
not complicated by GI hemorrhage.

Discussion: Hospital discharge transfer to a rehabilitation center decreases the odds of 6-month readmissions. The odds of readmission are higher in patients admitted to private hospitals. Females had significantly higher odds of readmission compared to males. Other strong predictors of readmissions included COPD, anemia, and CKD. Based on the Kaplan-Meier mortality trend, group with GI hemorrhage had 2-fold higher mortality, despite no significant difference in readmissions.
