Introduction: Ventricular tachycardia (VT) is a significant cause of morbidity and mortality in patients with heart failure with reduced ejection fraction (HFrEF). Hypothesis: Data on efficacy, safety, and outcomes of catheter ablation for VT in HFrEF have not been studied well. Methods: The 2002-2014 Nationwide Inpatient Sample (NIS) was used to identify all hospitalizations with a principle diagnosis of VT (International Classification of Diseases, Ninth Edition, Clinical Modification [ICD-9-CM] code 427.1) and a secondary diagnosis of HFrEF. Patients who underwent catheter ablation were identified using ICD-9-CM procedure code 37.34. Results: Of 228,557 patients with HFrEF & VT, 5845 (2.56%) underwent catheter ablation. The prevalence of Diabetes Mellitus (DM) and Chronic Kidney disease (CKD) was higher in the reference population contrary to a higher prevalence of prior myocardial infarction (MI), coronary bypass and AICD in those undergoing CA. The frequency of complications in the ablation group was 19.47%, the most common being post-operative hemorrhage (8.3%). This was followed by myocardial infarction (5.34%), pericardial complications (3.38%), and neurological complications (2.14%) (Figure 1.). The odds of in-hospital mortality were lower in the CA group compared to the reference group (5.08% vs 9.42%, p<0.05). Conclusions: Compared to medical therapy, VT ablation in HFrEF is associated with lower mortality though with significant complication rate. This suggests a need for future studies identifying the safety measures in VT ablations and instituting appropriate interventions to improve overall VT ablation outcomes.
