Anesthetic Management for Ventricular Tachycardia Ablation: A National Anesthesia Clinical Outcomes Registry Analysis
Authors' conclusion
GA has remained the primary anesthetic type for VT ablation despite the 2019 Expert Consensus Statement on Catheter Ablation of Ventricular Arrhythmias suggested its avoidance in idiopathic VT.
Study context
- Population
- Adults (≥18 years) undergoing elective ventricular tachycardia (VT) ablation, 2013–2021, National Anesthesia Clinical Outcomes Registry
- Participants
- 15,505 adults
- Exposure
- Monitored anesthesia care (MAC) vs general anesthesia (GA) for VT ablation, before vs after the 2019 Expert Consensus Statement
- GAn = 9,790
- Outcome
- Anesthetic type for VT ablation
Methodological detailsregistry analysis, interrupted time-series analysis, multivariate analysis
- Registry analysis
- Interrupted time-series analysis
- Multivariate analysis

Further findings
| Outcome | Estimate | P value |
|---|---|---|
| Change in MAC use after 2019 consensus statement (interrupted time series)Post-consensus statement | aOR (immediate change in intercept) 1.41 | P = 0.1629 |
| Change in MAC use after 2019 consensus statement (interrupted time series)Post-consensus statement | aOR (change in slope) 1.06 per quarter | P = 0.1591 |
Change in MAC use after 2019 consensus statement (interrupted time series)
- No statistically significant increase in MAC
Factors associated with anesthetic approach (multivariate)
- Sex, ASA physical status, age and geographic location significantly associated with anesthetic approach
