European Stars and Stripes (Newspaper) - September 17, 1985, Darmstadt, Hesse                                Tuesday. September 17. 1985 the stars and stripes a 1 Page experts seek to improve Jarvik-7 heart Tucson. Ari. Not researchers have begun to design improvements in the Jarvik-7 artificial heart to Correct a design flaw that preliminary tests1 Point in As a partial explanation of the strokes that  seriously complicated its use. The tests being performed arc the first in a Jarvik-7 heart removed from a patient Whu suffered strokes while living with the device. The tests Are being done at symbiont of Salt Lake City which makes the Jarvik-7 hearts on the device that was removed from Michael Drummond a 25-year-old Ari Ona Man. Me suffered mild strokes seven Days after receiving the implant and two Days before he received a human heart transplant. Researchers considered the findings unusually important not Only because it was the first Lime blood clots were present in an artificial heart removed from a patient but also because the interval Between the strokes and removal of the device was very Short. Clots in the left Side of the heart appear to have been the source of the fragments that broke off and rave led in the blood to Lodge in Drummond s brain to cause his strokes according to lectures by and inter views with or. Don b. Olson who Heads the artificial heart unit at the University of Utah where the Jarvik-7 was developed and or. Mark m. Levinson one of Drury mind s surgeons. Six people have had implants of Jarvik-7 hearts. The two who have died. Or. Barney Clark and Jack Burcham did not suffer strokes. In addition to Drummond three other Jarvik-7 recipients who did suffer strokes As complications remain alive. They arc William j. Schroeder and Murray i. Haydon in Louisville and Leif Stenberg in Stockholm Sweden. Volunteers for the artificial heart Experiment agree loan autopsy in which the de vice is removed for detailed examination such As with a scanning Electron Micro scope. The Jarvik-7 was used As a temporary measure in Drummond until doctors could obtain a human heart for him. He is now reported to be recuperating uneventfully from his strokes and transplant surgery. Biopsy tests of his new heart have shown that he is emerging from a critical period in his recovery without evidence of his body s rejecting the transplanted heart. Olsen said that tests on Drummond s artificial heart showed that blood clots had formed in tiny crevices near where the left ventricle the main pumping chamber was Quick connected or snapped to his an run the body s main artery.  showed pictures of the blood clots in this area As Well As on the right Side of Drummond s artificial heart at a dinner meeting of Tucson heart specialists last week. Okyn also  at the meeting and in lecture at the medical Tenter. Of the clot Ling Artmond the Quick connect he said that j.imk-7 researchers had not identified this is a problem in earlier experiments using the artificial heart in calves and sheep. The by Ixl system of these Ani Mals differs from that of humans. Of 120 animals receiving artificial heart implants three suffered strokes and in each of those cases the source was an infected clot of bacteria that formed in the device Olson said. We had Ero strokes in the 117 Ani Mals that did not have infection said Olsen. A veterinarian who was an innovator of the technique used to implant the artificial heart. He has taught Many of the Pioneer ing surgeons How to do the implant opera Tion. The artificial heart is implanted piece by piece in the body. Some components Are snapped together by the so called Quick connect system that Olson said his team designed about 10 years ago in the fashion that Tupperware lids slip Over and cd in place. Although the design of the Quick connector worked Well in the animals it a in t adequate in the human being because there were Small crevices Small areas where blood was trapped and clots formed Ouen said it was these Small crevices in this Quick connect system that led to what we suspect to be the problem Olsen said Olson said that i team at the University of Utah would begin testing the new design of the artificial heart next month. If leis ure successful he said he believed it would be a very Short time before the changes would be incorporated in the Jar Vik-7 hearts implanted in humans. The clots in Drummond s artificial heart Are undergoing further pathological tests to determine if they were formed by platelets the Liny fragments that help blood clot or by red blood cells. Itch of the three teams that have implanted Jarvik-7 hearts in humans has used a different regimen of anticoagulant drugs which help reduce the formation of but did clots making it difficult to compare their results and to identify the most effective therapy.
