Abstract

Background: Catheter ablation is an effective therapy for ventricular tachycardia (VT) and is increasing in use. Assessment of contemporary real-world outcomes of VT ablation requires data inclusive of both inpatient and outpatient encounters.

Objective: To assess factors associated with one-year in-hospital mortality, all-cause readmission, and recurrent readmission for VT following VT ablation, along with the associated costs of care.

Methods: Inpatient and outpatient VT ablations were captured in the Healthcare Cost and Utilization Project data in Florida, Maryland, and New York from 2016-2020 with one year follow up through 2021. Cox proportional hazards regression was used to identify risk factors associated with one-year in-hospital mortality, all-cause readmission, and recurrent VT readmission. Costs of inpatient cases and readmission were captured.

Results: Among 3,899 patients undergoing VT ablation, 2% died during the initial episode of care. The one year in-hospital mortality rate, all-cause readmission rate, and recurrent VT readmission rate were 6.8%, 43.4%, and 16.9%, respectively, and were broadly stable over the study period. Coronary artery disease, chronic kidney disease, and heart failure were independently associated with an increased risk of in-hospital mortality and all-cause readmission within one year (p<.05). Recurrent VT was the most common cause of readmission. All-cause readmissions increased costs by 55%.

Conclusion: Mortality, long-term readmission, and recurrent VT remain high following VT ablation, and include measurably important costs. Strategies to improve freedom from recurrent VT while managing comorbid conditions may serve as targets for improving the efficacy and cost-effectiveness of an important procedure applied to a vulnerable population.

期刊介绍: HeartRhythm, the official Journal of the Heart Rhythm Society and the Cardiac Electrophysiology Society, is a unique journal for fundamental discovery and clinical applicability. HeartRhythm integrates the entire cardiac electrophysiology (EP) community from basic and clinical academic researchers, private practitioners, engineers, allied professionals, industry, and trainees, all of whom are vital and interdependent members of our EP community. The Heart Rhythm Society is the international leader in science, education, and advocacy for cardiac arrhythmia professionals and patients, and the primary information resource on heart rhythm disorders. Its mission is to improve the care of patients by promoting research, education, and optimal health care policies and standards.
