Cost-effectiveness analysis
The CEA will examine the cost of health care resources and health outcomes from the ablation procedure to 1-year postoperatively. The costs will include all health care utilization during this time. Health care utilization, and associated costs, related to the patients' condition, the procedure and adverse events will be the basis of a sensitivity analysis.

Brief Summary
This is a prospective multicenter randomized open-label study aiming to assess whether endocardial or endocardial-epicardial ablation is superior to the standard approach (i.e., Antiarrhythmic drugs) in achievement of long-term ventricular tachycardia (VT) treatment success.
Detailed Description
Comparison of Ventricular Tachycardia Ablation Strategies in Patients With Ischemic Cardiomyopathy (EPI VT) is a prospective multicenter randomized controlled study that is planned as a pilot study to include 100 patients. The aim of our study is to assess whether endocardial or endocardial-epicardial ablation is superior to the standard approach (i.e., Antiarrhythmic drugs) in the achievement of long-term ventricular tachycardia (VT) treatment success. Patients will be stratified into two groups depending on the history of taking antiarrhythmic medications (AAD) and each group will be further randomized 1:1 for endocardial and epicardial ablation vs endocardial only ablation in group who failed AAD. And in the group who didn't fail AADs patients will be randomized 1:1:1 into 3 groups: endocardial and epicardial ablation, endocardial only ablation or antiarrhythmic medications. Follow up planned at 3, 6 and 12 months, if VT recurrence is noted, repeated procedure (according to initially allocated group) or adjustment of medications (if AAD group) will be performed. Follow up at 3, 6 and 12 months is also planned after a repeat procedure/ medications adjustment.
Primary endpoints include freedom from documented VT episodes (> 30 seconds) at 12 months after the first ablation procedure or on antiarrhythmic medication and freedom from documented VT episodes (>30 seconds) at 12 months after the second ablation procedure or on two antiarrhythmics combined.

Interventional Study Model
Parallel Assignment
Model Description
A total of 100 patients will be randomized in 1:1 fashion to investigation arms Endocardial - Epicardial (20 patients) or Endocardial ablation (20 patients) if patients have previously failed AAD and in 1:1:1 fashion randomization to Endocardial - Epicardial ablation (20 patients), Endocardial ablation (20 patients) and AAD (20 patients) if patients have not failed AAD previously. If during follow up VT recurrence occurs, treatment method that patient was assigned to will be considered failed and patients will undergo redo ablation (same as previously assigned to) or if AAD failed patient will be added a second AAD or changed to another AAD. If during follow up after second procedure or adjustment of AAD patient experiences VT recurrence the treatment method will be considered failed.
Masking
Outcomes Assessor
Masking Description
