Impact of Hospital Ventricular Tachycardia (VT) Ablation Volume on Postprocedural Complications: Argument for Selective Referral to High-Volume Centers
Authors' conclusion
Patients undergoing VT ablation at HVH were sicker on average, yet had lower in-hospital mortality and procedure-related morbidity compared to LVH. Selective VT patient referral to HVH has the potential to substantially reduce in-hospital complications following VT ablation nationally.
Study context
- Population
- Hospital admissions for VT ablation in the United States during 2019
- Exposure
- HVH vs LVH, with LVH as reference
- Outcome
- Heart failure (baseline comorbidity)
Methodological detailsUnited States, year 2019, hospitals divided into tertiles of VT ablation volume
