Lawrence Faucette, 58, has died nearly six weeks after receiving a genetically modified pig heart transplant. The heart had seemed healthy for the first month but began showing signs of rejection in recent days. The University of Maryland School of Medicine will continue to study the procedure and use the data from Faucette’s case to help understand the potential of this technology and improve outcomes for future patients. The hospital also expressed its condolences to Faucette’s family and friends.
