Staged kidney implantation with hypothermic oxygenated machine perfusion during combined heart and kidney transplants

Staged Kidney Transplantation During Combined Heart/Kidney Transplantation

NA · Cedars-Sinai Medical Center · NCT06877169

This trial will test whether keeping the donor kidney on oxygenated machine perfusion and implanting it later helps adults who are receiving both a heart and a kidney transplant.

What this trial studies

Combined heart and kidney transplantation treats patients with advanced heart failure and kidney disease but poses logistical and physiologic challenges that can harm the kidney graft. Anticoagulation, inotropes, and hemodynamic instability during heart implantation can worsen ischemia-reperfusion injury, while delaying implantation increases cold ischemic time. This study uses hypothermic oxygenated ex vivo machine perfusion to preserve the donor kidney and implements a planned delayed (staged) implantation to allow recipient stabilization after heart transplant. Outcomes include safety endpoints and measures of kidney graft function such as incidence of delayed graft function and need for dialysis in the first week.

Who should consider this trial

Good fit: Ideal candidates are adults at Cedars-Sinai scheduled for a planned combined heart and kidney transplant who can undergo staged (delayed) kidney implantation and have not opted out of research.

Not a fit: Patients who require immediate simultaneous heart and kidney implantation for medical necessity, those flagged as research opt-out in the electronic record, or those unable to return for post-operative follow-up are unlikely to benefit.

Why it matters

Potential benefit: If successful, this approach could reduce delayed graft function and improve early kidney graft survival after combined heart-kidney transplants.

How similar studies have performed: Hypothermic oxygenated machine perfusion has shown promise in reducing ischemia-reperfusion injury and delayed graft function in other kidney transplant settings, but planned delayed implantation during combined heart-kidney transplantation is relatively novel with limited prior data.
