Title: David Bennett Sr. Content: David Bennett Sr. (1964 – March 8, 2022) was an American medical patient. He was the first patient to have a xenotransplantation with a genetically modified heart. On January 7, 2022, aged 57, he received the heart of a gene- edited pig. He was born in Maryland. Bennett died in Baltimore, Maryland on March 8, 2022, at the age of 57. ==Disease, transplantation and death== Bennett suffered from advanced heart failure, accompanied by cardiac arrhythmias.https://www.washingtonpost.com/health/2022/03/09/pig-heart- transplant-bennett/ Due to insufficient adherence to therapy - among other things, he had not made sufficient efforts to control his blood pressure - the treating physicians saw him as unsuitable for an allotransplantation. There were doubts as to whether, given the very scarce human organs, one should be able to give one to a person whose subsequent compliance was not assured. Therefore, with Bennett's approval, an exemption was sought from the Food and Drug Administration to perform a pig heart transplant.https://www.science.org/content/article/here-s-how-scientists- pulled-first-pig-human-heart- transplanthttps://www.nature.com/articles/d41586-022-00111-9 The procedure took place on January 7, 2022 and was performed by US cardiac surgeon Bartley P.

The patient had survived the typical period of a rapid rejection reaction, was conscious and reflected on his situation. He knows it's "a shot in the dark," but it's his last chance. The clinic quoted him as saying he was looking forward to getting up soon.https://science.orf.at/stories/3210835/ By January 18, Bennett was off the heart-lung machine and able to communicate with those around him.https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(22)00097-6/fulltext One month after the procedure, it was reported that the patient remained bedridden. Attempts were made to mobilize him with physiotherapy.https://healthyduck.org/recipient-of-pig-heart-undergoing- physiotherapy-for-first-time-says-university-of-maryland-cbs-baltimore/ A rejection reaction to the foreign organ had not materialized until then.Patient with transplanted pig heart is doing well Two months after the transplant, Bennett died on March 8, 2022,https://www.bbc.com/news/health-60681493 after his health had deteriorated over a few days.https://www.medschool.umaryland.edu/news/2022/IN- MEMORIAM-David-Bennett-Sr.html About two months after Bennett's death, doctors announced that he had been diagnosed with a swine virus. It was also said that it was possible that the virus had been the cause of death. It could also have been silent and had no effect on the patient. A combination with other factors contributing to the cause of death can also be considered.https://www.theguardian.com/us-news/2022/may/06/man-landmark-pig- heart-transplant-death-pig-virus
