What this trial studies

The US National OCS Heart Perfusion Registry is an observational registry aimed at collecting data on the clinical outcomes of heart transplant recipients who receive donor hearts preserved with the OCS Heart System. This multi-center initiative will follow patients for up to five years post-transplant to assess the performance of the OCS Heart device in real-world settings after its FDA approval. The registry will provide valuable insights into the effectiveness and safety of this preservation method in heart transplantation.

Who should consider this trial

Good fit: Ideal candidates for this registry are heart transplant recipients who have received a donor heart preserved with the OCS Heart System.

Not a fit: Patients who do not receive a heart transplant or those who receive a heart not preserved with the OCS Heart System may not benefit from this registry.

Why it matters

Potential benefit: If successful, this registry could enhance understanding of heart transplant outcomes and improve patient care through better preservation techniques.

How similar studies have performed: While this registry is focused on a specific device, similar observational studies have shown success in documenting post-transplant outcomes and improving clinical practices.
