A Neonatal ABO non‐compatible heart transplant from a circulatory‐determined death donor using NRP/Cold storage

Background Donation after Circulatory death is gaining worldwide acceptance. Most protocols regard their first cases to be performed with donor and recipient in the same institution. Few records of children or distant procurement have been published. Methods Our institution was offered a heart from a 3‐day‐old, 3.4‐kg child, blood group A, suffering irreversible encephalopathy. Parents accepted withdrawal of life‐sustaining therapy and agreed to donation. The donor hospital was located 340 km away. Concomitantly, a 2‐month‐old, 3.1 kg, blood group type B and with non‐compaction ventricles was awaiting for the heart transplant in our unit. Results Thirty‐seven minutes after withdrawal of life‐sustaining therapy, the heart arrested. Five minutes afterwards, a sternotomy was performed. The supra‐aortic vessels were clamped altogether. Aorta and right appendage were cannulated and connected to heart‐lung machine. The innominate artery above the clamp was severed. The heart resumed spontaneous rhythm in less than 1 min. Ventilation was restored and extracorporeal circulation was maintained for 32 min. Upon cardiologic arrest, the graft was harvested as routinely. The heart was cold‐stored and transported by plane to our Hospital. An orthotopic bicaval transplant was performed. Overall cold ischaemia was 245 min. Ten weeks later, the child was discharged home in good condition. Conclusion Donation in circulatory death could increase the pool in neonates. Extracorporeal circulation proves successful for procurement in neonates. Distant procurement plus cold storage for donation in circulatory death is feasible. Donation in circulatory death and ABO non‐compatible strategies are complementary to each other.
