Prolonged hospitalization after catheter ablation of ventricular tachycardia: Predictors and outcomes
Authors' conclusion
Prolonged postablation hospitalization after VT ablation adversely affects outcomes in high-risk patients but not in low-/moderate-risk patients. Procedural factors, such as prolonged ablation duration, are modifiable predictors in low-/moderate-risk populations. Baseline disease severity factors dominate in high-risk groups.
Study context
- Population
- Patients with structural heart disease undergoing ventricular tachycardia (VT) catheter ablation, January 2022 to October 2024
- Participants
- 318 patient cases
- Exposure
- Prolonged vs non-prolonged postablation hospitalization
- Prolonged hospitalizationn = 95
- Outcome
- Predictors of prolonged hospitalization (>3 days) after VT ablation and their impact on outcomes (mortality, LV assist device implantation, cardiac transplant)
Main finding
As reported in the abstract
Predictors of prolonged hospitalization (postablation LOS > 3 days)

- Nonelective ablation
- OR 7.42; P < 0.001
- Acute procedural complication/pericardial effusion
- OR 4.30; P = 0.048
- Prolonged postablation hospitalization
- 95 cases (29.9%)
Observational data: associations, not effects.
Further findings
| Outcome | Estimate | P value |
|---|---|---|
| Death, LV assist device implantation or transplant, by PAINESD stratum (subgroup)High-risk (PAINESD ≥ 17) · Cox survival analysis | HR 3.35 | P = 0.008 |
| Prolonged procedural duration (> 255 minutes) as predictor, by PAINESD stratum (subgroup)Low-/moderate-risk patients | OR 2.89 | P = 0.010 |
Death, LV assist device implantation or transplant, by PAINESD stratum (subgroup)
- Not associated in low-/moderate-risk patients (PAINESD < 17)
Prolonged procedural duration (> 255 minutes) as predictor, by PAINESD stratum (subgroup)
- Not a significant predictor in high-risk patients
