The Use of Impella RP Support System in Patients With Right Heart Failure

Inclusion Criteria:

1. Patients that have developed signs of right ventricular failure either: A) within 48
hours post-implantation of an FDA approved implantable surgical LVAD (left

48 hours post surgery or post myocardial infarction (Cohort B).

2. Age ≥18 years old

3. Signed Informed consent

Exclusion Criteria

1. INTERMACS 1 patients (Critical cardiogenic shock patient who is "crashing and
burning", has life-threatening hypotension and rapidly escalating inotropic or
pressor support, with critical organ hypoperfusion often confirmed by worsening
acidosis and lactate levels)

2. Evidence of acute neurologic injury

3. RA(right atrium),RV (right Ventricle) and/or PA (pulmonary artery) thrombus

4. Intolerance to anticoagulant or antiplatelet therapies

5. Existing congenital heart disease that would preclude the insertion of the device.
