Abstract

Background: Despite the optimal efficacy of catheter ablation for ventricular tachycardia (VT), recurrence of VT can occur post-procedurally. However, data on the high-risk population for VT recurrence and the in-hospital outcomes remain scarce.

Objective: This study aimed to determine the predictors of 30-day readmission for recurrent VT after catheter ablation of VT and assess the in-hospital outcomes.

Method: Using the all-payer, nationally representative Nationwide Readmissions Database, we identified the patients aged ≥18 years who underwent catheter ablation for VT and were readmitted within 30 days because of recurrent VT from 2017 to 2020. We performed unweighted univariable and multivariable analyses to determine the outcomes and to identify the patient and hospital variables that were predictive of 30-day readmissions for recurrent VT. A p-value of <0.05 is considered statistically significant.

Results: In our analysis, a total of 4,102 patients were discharged alive after VT ablation, of which 278 (6.8%) were readmitted within 30 days for recurrent VT. Recurrent VT was also the most common cause of 30-day readmission (47.7%, n=278/583). Compared to non-recurrent VT readmission, readmission due to recurrent VT had higher mortality during rehospitalization (7.55% vs 3.72%, p<0.01) and higher cumulative hospitalization cost ($57584 vs $37846, p<0.01). Via multivariable analysis, congestive heart failure (aOR: 1.84; 95% CI: 1.07-3.17; P=0.03) and non-elective index admissions (aOR: 1.88; 95% CI: 1.32-2.68; P<0.01) were the independent predictors of 30-day readmission for recurrent VT.

Conclusion: Recurrent VT was the most common cause of 30-day readmission following VT ablation. Congestive heart failure and non-elective index admissions were the independent predictors of 30-day readmissions for recurrent VT. These highlight the importance of further research in ablation strategies to improve the efficacy of VT ablation.
