Assess Safety and Probable Benefit of the EXCOR® Pediatric Ventricular Assist Device Under a Continued Access Protocol (CAP)

Inclusion Criteria:

- Severe New York Heart Association (NYHA) Functional Class IV (or Ross Functional Class IV for patients <= 6 years) heart failure refractory to optimal medical therapy, and has met at least one of the following criteria:

• INTERMACS profile status 1 or 1A, i.e. critical cardiogenic shock (low BP unresponsive to support), compromised end organ perfusion, < 24 hour survival without mechanical support; may be due to Ventricular Tachycardia (VT)/Ventricular Fibrillation (VF) (1A) OR
• INTERMACS profile status or 2A (i.e progressive decline): not in imminent danger, but worsening despite optimal inotropic therapy; may be due to VT/VF (2A) AND at least one of the following criteria: Decline in renal functions, Decline in nutritional status, Decline in mobility/ambulation
