Contents:

  1. Indications for mechanical support
    1. Deterioration of an established prospective transplant recipient
    2. Patient unable to be weaned from cardiopulmonary bypass but is a candidate for “postcardiotomy” usage or “bridging” to transplantation
    3. Acute myocardial infarction with balloon-dependent left heart failure

  2. Respiratory failure
    1. Indications for ECMO
