Points that support the claim: Performed at the University of Maryland Medical Center by a named team led by Dr. Bartley Griffith on January 7, 2022, under an FDA compassionate-use authorization, and documented in the institution's own account and across major science press — a measurable surgical event, not a claim; and Objective, closely tracked clinical course: the pig heart beat with no sign of acute rejection for nearly seven weeks, the first genetically modified pig heart ever to function in a living human. Points that cut against it: Nothing here is unexplained. The heart came from a pig with ten gene edits engineered specifically to evade human rejection, and a complete biological account of how it worked is known — this is the defining reason the Miracle Meter is near the floor; and Bennett died about two months later, on March 8, 2022. His team attributed the outcome to several overlapping factors — a severely immunocompromised, gravely ill patient and a pig virus (PCMV) later found in the graft. The limits of the therapy are as documented as its success.
