Impact of age on hospital outcomes after catheter ablation for ventricular tachycardia

The real‐world data on the safety profile of ventricular tachycardia (VT) ablation among elderly patients is not well‐established. This study aimed to evaluate the procedural outcomes among those aged 18–64 years versus those aged ≥65 years who underwent catheter ablation of VT.Using the Nationwide Readmissions Database, our study included patients aged ≥18 years who underwent VT catheter ablation between 2017 and 2020. We divided the patients into non‐elderly (18–64 years old) and elderly age groups (≥65 years old). We then analyzed the in‐hospital procedural outcome and 30‐day readmission between these two groups.Our study included 2075 (49.1%) non‐elderly patients and 2153 (50.9%) elderly patients who underwent VT ablation. Post‐procedurally, elderly patients had significantly higher rates of prolonged index hospitalization (≥7 days; 35.5% vs. 29.3%, p < .01), non‐home discharge (13.4% vs. 6.0%, p < .01), 30‐day readmission (17.0% vs. 11.4%, p < .01), and early mortality (5.5% vs. 2.4%, p < .01). There was no significant difference in the procedural complications between two groups, namely vascular complications, hemopericardium/cardiac tamponade, cerebrovascular accident (CVA), major bleeding requiring blood transfusion, and systemic embolization. Through multivariable analysis, the elderly group was associated with higher odds of early mortality (OR: 7.50; CI 1.86–30.31, p = .01), non‐home discharge (OR: 2.41; CI: 1.93–3.00, p < .01) and 30‐day readmission (OR: 1.58; CI 1.32–1.89, p < .01).Elderly patients have worse in‐hospital outcome, early mortality, non‐home discharge, and 30‐day readmission following catheter ablation for VT. There was no significant difference between elderly and non‐elderly groups in the procedural complications.
