Today, the Herz- und Diabeteszentrum Nordrhein-Westfalen in Bad Oeynhausen has announced in a press release that their first blood group incompatible heart transplant using Glycosorb® ABO has been performed and with excellent results. The transplant was performed on a two-year-old girl, and she has now been able to celebrate her two-year-old birthday at home. The girl came to the hospital five months ago as a result of an incurable genetic heart muscle disease and was put on the waiting list for transplant in July this year.

The chances of being transplanted with a suitable blood group compatible organ are however often very low for young children and waiting times are expected to increase.
In August, Eurotransplant declared that it had a donor heart suitable for the girl, but from an incompatible blood group. The hospital decided to use Glycosorb® ABO to facilitate the transplant. The treatment with Glycosorb® ABO went excellent and the girl was successfully transplanted. The treatment is performed by incorporating Glycosorb® ABO into the cardiopulmonary bypass system
during the transplant.  
“By allowing blood group incompatible heart transplantation it is possible to significantly increase their chances of survival and, above all, reducing the waiting time'' said the clinic director of Bad Oeynhausener Kinderherzzentrum.

The method of incorporating Glycosorb® ABO into the cardiopulmonary bypass system was introduced in 2015 at Great Ormond Street Hospital (GOSH) in London. GOSH has published three articles on the subject1,2,3. The results are excellent and have shown significant advantages over the previously used method.

In 2021, BBC wrote about Lucy, a 10-year-old girl, who is thought to be the oldest child in the world to receive a blood group incompatible heart (link). The GOSH method has also been introduced at other heart transplant centers in Europe.
