Patient with ischemic heart disease (IHD) with a meaningful survival >1 year expected

 • LVEF < 35%,  NYHA class II or Ill HF despite guideline-directed management and therapy

      or 

 • LVEF < 30%, NYHA class I HF despite guideline-directed management and therapy

Do all of the following apply?

 • Low left ventricular ejection fraction (LVEF) due to IHD

 • > 40 days post-myocardial infarction

 • > 90 days postrevascularization

Or ANY of the following: 

 • Sudden cardiac arrest due to ventricular tachycardia (VT) or ventricular fibrillation (VF)

 • Hemodynamically unstable VT

 • Stable VT
