Epicardial mapping and ablation is a viable and successful approach for recurrent non-ischaemic ventricular tachycardia when endocardial ablation fails.

May support epicardial ablation in refractory non-ischaemic VT; hypothesis-generating and requires prospective confirmation.
Radiofrequency ablation is a therapeutic option for recurrent ventricular tachycardia (VT) in both ischaemic and non-ischaemic subsets. Usually this is attempted by mapping endocardially; however, in some situations epicardial approach may be needed to access the VT circuit. We report two cases in which epicardial approach was used to successfully ablate the VT, when endocardial ablation was ineffective.
