A, Kaplan–Meier plot illustrating survival rates free from the combined study end point (sustained ventricular tachycardia/ventricular fibrillation, heart transplantation, and death) after the index procedure. The graph shows data for the whole study cohort (n=47). B, Kaplan–Meier plot illustrating survival rates free from the combined study end point after the index procedure stratified into an endocardial only and combined endo‐/epicardial approach (P=0.119). C, Kaplan–Meier plot illustrating survival rates free from sustained ventricular arrhythmia recurrence after multiple procedures. It shows a statistically non‐significant trend (P=0.058) towards a better outcome for patients receiving a combined endo‐/epicardial procedure as compared with patients only receiving endocardial catheter ablation. Endo indicates endocardial; epi/endo, epi‐/endocardial.
