I want to live. I know it&#8217;s a shot in the dark, but it&#8217;s my last choice,&#8221; the Maryland resident said a day before the surgery.<\/p>\n<p>Bennett, who has spent the last several months bedridden on a heart-lung bypass machine, added: &#8220;I look forward to getting out of bed after I recover.&#8221;<\/p>\n<p>The Food and Drug Administration granted emergency authorization for the surgery on New Year&#8217;s Eve, as a last ditch effort for a patient who was unsuitable for conventional transplant.<\/p>\n<\/div>\n<div>\n<p>&#8220;This was a breakthrough surgery and brings us one step closer to solving the organ shortage crisis,&#8221; said Bartley Griffith, who surgically transplanted the pig heart.<\/p>\n<p>&#8220;We are proceeding cautiously, but we are also optimistic that this first-in-the-world surgery will provide an important new option for patients in the future.&#8221;<\/p>\n<p>Muhammad Mohiuddin, who co-founded the university&#8217;s cardiac xenotransplantation program, added the surgery was the culmination of years or research, involving pig-to-baboon transplants, with survival times that exceeded nine months.<\/p>\n<\/div>\n<div>\n<p>&#8220;The successful procedure provided valuable information to help the medical community improve this potentially life-saving method in future patients,&#8221; he said.<\/p>\n<p><strong id=\"strong-720a888a2724ed56bb85535e3bbbd4b3\">&#8211; 10 unique gene edits &#8211;<\/strong><\/p>\n<p>Bennett&#8217;s donor pig belonged to a herd that had undergone genetic editing procedures.<\/p>\n<\/div>\n<div>\n<p>Three genes that would have led to rejection of pig organs by humans were &#8220;knocked out,&#8221; as was a gene that would have led to excessive growth of pig heart tissue.<\/p>\n<p>Six human genes responsible for human acceptance were inserted into the genome, for a total of 10 unique gene edits.<\/p>\n<p>The editing was performed by Virginia-based biotech firm Revivicor, which also supplied the pig used in a breakthrough kidney transplant on a brain dead patient in New York in October.<\/p>\n<\/div>\n<div>\n<p>But while that surgery was purely a proof-of-concept experiment, and the kidney was connected outside the patient&#8217;s body, the new surgery is intended to save a person&#8217;s life.<\/p>\n<p>The donated organ was kept in an organ-preservation machine ahead of the surgery, and the team also used an experimental new drug made by Kiniksa Pharmaceuticals along with conventional anti-rejection drugs to suppress the immune system.<\/p>\n<p>About 110,000 Americans are currently waiting for an organ transplant, and more than 6,000 patients die each year before getting one, according to official figures.<\/p>\n<\/div>\n<div>\n<p>To meet demand, doctors have long been interested in so-called xenotransplantation, or cross-species organ donation, with experiments tracing back to the 17th century.<\/p>\n<p>Early research focused on harvesting organs from primates &#8212; for example, a baboon heart was transplanted into a newborn known as &#8220;Baby Fae&#8221; in 1984, but she survived only 20 days.<\/p>\n<p>Today, pig heart valves are widely used in humans, and pig skin is grafted on human burn victims.<\/p>\n<\/div>\n<div>\n<p>Pigs make the ideal donors because of their size, their rapid growth and large litters, and the fact they are already raised as a food source.<\/p>\n<p><strong id=\"strong-60a49dc45b28cbda13a4cadde7d7e836\"> Agence France-Presse<\/strong><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>by Issam Ahmed US surgeons have successfully implanted a heart from a genetically modified pig in a 57-year-old man, a medical first that could one day help solve the chronic shortage of organ donations.
