Exclusion Criteria: • Patient has any contraindication as specified in the current version of the IFU of the EXCOR® Pediatric VAD system as shown below: "Patients unable to tolerate systemic anticoagulation therapy should not be implanted with EXCOR components. Magnetic Resonance Imaging (MRI) is contraindicated in patients after being implanted with EXCOR. Patients with aortic valve regurgitation that is more than moderate that cannot be re- paired at the time of implantation should not be implanted with EXCOR.
