Table 3: Summary of Ablation Studies.

Study	Design	Comparison	Outcome
Segal et al.[22]	Prospective cohort	Mean shock frequency for VT pre/post ablation	Reduction in mean shock frequency post ablation
SMASH-VT[23]	Randomised	VT ablation vs no ablation in primary and secondary prevention patients	Reduction in ICD therapy in ablation group
VTACH[24]	Randomised	Prophylactic VT ablation + ICD implantation vs ICD alone post MI	Reduction in recurrent VT in ablation group
Frankel et al.[25]	Prospective cohort	Ablation after first VT episode vs ablation after subsequent episodes	Reduction in additional VT during follow-up in early ablation group

MI = myocardial infarction; VT = ventricular tachycardia.
