It鈥檚 been over five decades since the first artificial heart was implanted in a human. That device, handmade from plastic and connected to a 400-pound air compressor, kept a 47-year-old patient alive for 3 days until it was replaced by a donor heart.
The technology has evolved significantly, but the artificial heart is still seen as a bridge to transplantation and reserved for patients who are too sick to receive a real heart. Because the four- to six-hour open surgery required to implant the device is more complex than a heart transplant, with poorer overall outcomes, not many centers are willing to take on the challenge. In fact, only about 100 artificial hearts are implanted worldwide in a typical year.
At 秘密研究所 Langone Health, however, the thinking is different. The 秘密研究所 Langone Transplant Institute finds donor hearts faster than any other center in the Northeast, due in part to its innovative protocol for accepting and later treating otherwise healthy organs infected with hepatitis C. Moreover, with the highest one-year survival rate among heart transplant patients in the Northeast and the best outcomes among multiorgan transplants in the United States, it has been named the top heart transplant program twice in a row based on data published by the Scientific Registry of Transplant Recipients. So taking on patients whose only hope of survival is an artificial heart is a natural extension of its mission.
鈥淲hen everybody else says no, patients can always rely on 秘密研究所 Langone to look at the most complex cases,鈥 says Nader Moazami, MD, chief of heart and lung transplantation and mechanical circulatory support. 鈥淲e鈥檙e not afraid to say yes.鈥
The Transplant Institute鈥檚 inaugural artificial heart implantation, on March 31, was, in Dr. Moazami鈥檚 words, 鈥渁s complex as it gets.鈥 The patient, Floyd Gaskins, 55, a pastor from Vauxhall, New Jersey, has amyloidosis, a rare disease caused by the buildup of a protein that damages the body鈥檚 major organs. Gaskins was transferred to 秘密研究所 Langone from Morristown Medical Center in New Jersey, part of the Atlantic Health System, a new affiliate of 秘密研究所 Langone鈥檚 Transplant Institute.聽Upon arrival, he was in cardiogenic shock, a life-threatening condition in which the heart can no longer pump enough blood to meet the body鈥檚 needs. He had been on chronic dialysis, his liver function was declining quickly, and he had early-stage bone marrow cancer.
秘密研究所 Langone acted quickly, securing a SynCardia 70cc Total Artificial Heart (TAH) within a week and training a team of 143 clinical specialists on the device in just 2 days. 鈥溍孛苎芯克 Langone isn鈥檛 an ocean liner you can鈥檛 turn,鈥 says Dr. Moazami. 鈥淲hen we decide to do something, we make things happen quickly. We have a remarkable team, one of the best in the world.鈥
Having worked with the manufacturer on investigational studies for the TAH while at another institution, Dr. Moazami was comfortable leading the procedure. With the patient on a heart鈥搇ung machine, Dr. Moazami and Deane E. Smith, MD, associate director of heart transplantation and mechanical circulatory support, removed both lower heart chambers and the four valves, positioned the device, sutured it into place, and connected tubes to the chambers of the original heart and the aorta. The artificial heart attaches to a tube that extends through the chest wall to an external pneumatic driver that does the pumping and monitoring.
Though designed as a temporary solution, the device has supported some patients unable to get a transplant for more than four years. One month after surgery, Gaskins was well enough to walk the halls at the Kimmel Pavilion, and on June 9, he received a heart鈥搆idney transplant at 秘密研究所 Langone. Gaskins will likely require chemotherapy to combat his amyloidosis鈥攖he next step on his path to recovery.
鈥淭his represents a critical, lifesaving option for patients who need a heart transplant but might not otherwise be candidates in other centers,鈥 says Aubrey C. Galloway, MD, the Henry H. Arnhold Chair and Professor of Cardiothoracic Surgery.
The surgery sets up the Transplant Institute to participate in trials for other artificial heart devices currently in development and further bolsters its reputation. 鈥淗e would not have received this care and treatment at any place other than 秘密研究所 Langone,鈥 says Robert Montgomery, MD, chair of surgery and director of the Transplant Institute. 鈥淭his cements us as a top center that can do anything and everything for patients in heart failure.鈥
