Bartley P. Griffith (born 1949) is an American heart surgeon.[2]
Griffith joined Muhammad Mohiuddin's MD Xenoheart laboratory in 2018. Together, they were able to demonstrate that the heart of a genetically altered pig could support life when transplanted into an orthotopic position in the chest for up to 9 months. Griffith and Mohiuddin performed the first successful xenotransplantation of a genetically modified pig heart to a human on January 7, 2022.[3] The recipient was 57-year-old David Bennett Sr. The procedure occurred at the University of Maryland Medical Center.[4] Due to complications, David Bennett Sr died on March 8, 2022.[5]
On September 20, 2023, Bartley P. Griffith performed his second pig heart transplant.[6]
