• W4377014976 abstract "Catheter ablation is an established treatment modality for ventricular tachycardias (VTs). There is, however, a paucity of data regarding the characteristics and outcomes of patients hospitalized for elective vs those who underwent urgent VT ablation. To determine baseline characteristics and in-hospital outcomes of patients hospitalized for elective vs. urgent VT ablation. Patients hospitalized for elective or urgent VT ablation were abstracted along with their comorbidities using relevant International Classification of Diseases - 10th Modification diagnosis codes. Baseline characteristics of the two cohorts, elective vs urgent VT ablation, were analyzed. Univariable and multivariable analyses were then performed for the primary outcome of death and secondary outcomes of length of stay, cost, need for mechanical and ventilatory support. From 2016-2020, we identified 43,690 patients who underwent VT ablation during their hospitalization. A total of 10,385 (23.8%) patients were elective hospitalizations and 33,305 (76.2%) were urgent. Mean age of patients in both cohorts was 64 years, predominantly male (76% vs 23%) and Caucasian. The elective cohort patients were more likely to have private insurance (32.1% vs 27.0%) and had fewer comorbidity burden [Charlson Comorbidity Index (CCI) of ≥3: 47.4% vs 58.3%]. Hypertension (46.1% vs 50.5%), dyslipidemia (53.7% vs 55.0%), diabetes (28.5% vs 33.5%), chronic kidney disease (11.0% vs 17.0%), coronary artery disease (50.9% vs 57.5%), and heart failure (73.8% vs 78.1%) were all lower in the elective cohort vs. the urgent cohort. The primary outcome of mortality was lower in the elective cohort (1.9% vs 3.4%; p=0.005) after adjusting for age, sex, race, and comorbidities. Mean LOS (5.1 vs 8.7 days; p<0.001), mean hospitalization costs ($229,684 vs. $264,374; p<0.001), and need for mechanical ventilation (5.8% vs 8.9%; p<0.001) were also lower in the elective cohort, after adjustment for comorbidities. Acutely hospitalized patients undergoing VT ablation have a higher comorbidity burden, higher in-hospital mortality, LOS and total incurred hospitalization cost. This study comprising a large, nationally representative patient population, yields evidence of poorer outcomes in patients undergoing urgent VT ablation. Future studies are necessary to further understand and minimize adverse outcomes in these patients." @default.
