Montgomery had a mustache that made him look like Wyatt Earp, though it was less dramatic than the one he had had before Covid; he had trimmed it for heightened hygiene protocols. Before they are transplanted, pig hearts require genetic modification to reduce the risk of rejection and to ensure proper function. Researchers also knock in certain genes to perform some important human biological processes. There were many occasions where I thought, Did I make the right decision? Mohiuddins work eventually led to transplants of pig hearts into baboons; after nine hundred and forty-five days, the baboons were still thriving.

What HBOs Chernobyl got right, and what it got terribly wrong. A trial was conducted of patients who would otherwise not have received kidneys but who consented to receive hep-C-positive organs, and were subsequently treated for hep C. Later, the trial was expanded to hep-C-positive hearts. U.A.B. The researchers also prevent the expression of genes that would allow the heart to grow larger once inside the person receiving the transplant and exposed to human growth hormone. And while the first pig heart transplant in a living patient ended in the patient's death in Maryland nearly two months later, his outcome was complicated by a pig virus later found in the transplanted heart.
