Endo-ePIcardial Versus Endocardial Only Catheter Ablation for ISchemic Driven Ventricular Tachycardia (EPISODE VT)

Prior treatment

• Previous heart surgery.

Other illness

• Acute conditions that prevent ablation (including active infection, overt hyperthyroidism and others listed below).
• Active neoplastic disease.
• Heart failure with NYHA IV.

Lab values

• Left ventricle ejection fraction \< 20%.
• Renal failure (eGFR \< 20 mL/min/1.73m2).

Other

• Obesity with BMI \> 40 kg/m2.
• Pregnancy or breastfeeding.
• Fresh ballot thrombus in the left ventricle.
• Suspicion of massive adhesions in the pericardium that may impede pericardial puncture.
• Ablation of the post-infarction VT in the left ventricle in medical history.
• Life expectancy less than 12 months.

• Status after myocardial infarction (minimum 3 months before inclusion in the study).
• Documented post-infarction VT or VF.
• Implantable ICD (at least 2 weeks before ablation) or CRT-D (at least 2 months before ablation).
• A history of at least one from below:
  • One or more high energy interventions.
  • Three or more adequate antitachycardia pacing therapies, including one symptomatic.
  • Three or more episodes of VT in 24 hours (interrupted by ATP or shock) - electrical storm.
  • Sustained VT recorded on ECG with a cycle length longer than the ICD detection threshold.
• Age between 18 and 85 years.
• Signed informed consent to participate in the study.
