| COR | LOE | Recommendations |
|---|---|---|
| I | C‐EO | 1. Patients with certain underlying medical conditions and comorbidities undergoing complex VA ablations who are deemed to have increased procedural risk should undergo procedures in a hospital‐based electrophysiology laboratory. |
| I | C‐EO | 2. Onsite interventional cardiology expertise is recommended for electrophysiology procedures requiring coronary imaging to delineate coronary anatomy for epicardial ablation, aortography to delineate coronary ostia for SV VT ablation, and need for placement of HS devices. |
| I | C‐EO | 3. Onsite cardiothoracic surgical backup is recommended for electrophysiology procedures requiring pericardial access due to the potential need for emergent sternotomy and cardiopulmonary bypass. |
| I | C‐EO | 4. Availability of anesthesia personnel is recommended for all patients undergoing catheter ablation of VAs. |
