In early 2022, doctors in Maryland transplanted a genetically modified pig heart into a human patient (NBC News, CBS Baltimore). For the purposes of this question, an "organ" would be a heart, intestine, kidney, liver, lung, or pancreas (Cleveland Clinic). The xenotransplantation attempt must take place in an EU member state to count, though the nationality of the doctors and patient would be immaterial. For information on the current state of EU policy on the matter, see: https://www.europarl.europa.eu/RegData/etudes/ATAG/2022/697212/EPRS_ATA(2022)697212_EN.pdf.
