Indications for catheter ablation of ventricular tachycardia in adults with CHD
| COR | LOE | Recommendation |
|---|---|---|
| I | C | Catheter ablation is indicated as adjunctive therapy to an ICD in adults with CHD, recurrent monomorphic ventricular tachycardia, and multiple appropriate shocks that are not manageable by device reprogramming or drug therapy |
| IIa | C | Catheter ablation can be considered for symptomatic sustained monomorphic ventricular tachycardia in adults with CHD and ICDs as an alternative to drug therapy |
| IIb | C | Catheter ablation may be reasonable in adults with CHD and frequent ventricular ectopy associated with deteriorating ventricular function |
| III | C | Catheter ablation alone is not considered appropriate prophylactic therapy in adults with CHD deemed to be at increased risk for sudden cardiac death |

For COR green denotes class I, light orange class IIa, dark orange class IIB, and red class III. For LOR dark blue denotes grade B and light blue grade C.
CHD, congenital heart disease; COR, class of recommendation; ICD, implantable cardioverter-defibrillator; LOE, level of evidence.
