The first American to carry an artificial heart: can go home without a heart
Release date: 2015-01-19 According to the Science Daily, the Frankel Cardiovascular Center at the University of Michigan allowed a person with an artificial heart disease to go home, the first in heart care in the Michigan area. The heart-driven device, called Freedom, weighs 13 pounds and is designed to protect patients with a late risk of dying from two-ventricular heart failure. This device makes Ipsilanti, Michigan, awaiting heart transplant. Stan Larkin, 24, is able to go home to spend Christmas with her family. He was the first patient to leave Michigan Hospital without a human heart. Thanks to this wearable technology, he became a member of a special group of heart patients with independent action in the United States. "Stan's equipment is the temporary artificial heart of Xinkadia. This mechanical pump can help him survive the days of waiting for a heart transplant," said Jonathan Haft, a cardiac surgeon at the University of Michigan. "He is still on the waiting list for heart transplants. We hope that as soon as we have the right organs, we will arrange a heart transplant for him as soon as possible. At the same time, he can wear this artificial heart to stay at home and return to normal life as soon as possible so that Surgery can be performed in the best condition when the opportunity comes." This artificial heart has two tubes that leave the body, which are connected to a machine that delivers compressed air to the ventricles, allowing blood to circulate throughout the body. Before the development of the portable free drive, the US Food and Drug Administration's only approved Xinkadia temporary artificial heart was driven by the "Big Blue" hospital, which weighed 418 pounds and was the size of a washing machine. Due to organ shortages, all artificial heart disease patients supported by Big Blue must stay in the hospital for months, even years, waiting for the right donation. The free-drive function, like the Big Blue, delivers compressed air to the ventricle, but it is portable. This marks an important milestone in replacing the failing heart in a time when heart disease is increasing and there is still no suitable donor heart. "I still have a lot of problems in my heart, but I can't wait to learn," said Larkin, who was on the hospital on December 23. "It keeps me alive, I can't wait to receive a heart transplant and live a normal life." How to deal with the late stage of heart failure According to the American Heart Association, 10% of the 5.7 million Americans with heart failure have severe heart failure. When a patient feels shortness of breath even at rest, he is diagnosed with severe heart failure. Even in the advanced stages, treatment options are limited to helping the heart twitch as much as possible. For more than a decade, ventricular assist devices (VADs) have been used to improve the quality of life and enhance survival of patients awaiting heart transplantation. When all treatment options—including medications, lifestyle changes, and cardiac procedures—are ineffective, this device can be used as the ultimate therapy. Unlike transitional therapy, the ultimate therapy requires the patient to use a left ventricular assist device for the rest of his life. These devices are often used to support the left side of the heart and are therefore referred to as left ventricular assist devices (LVADs), while other devices can be used to support the right side of the heart. If support is needed on both sides of the heart, then a full artificial heart may be needed. Brother's battle against heart failure Stan Larkin and his brother, Dominique Larkin, 23, are also fighting heart disease. In 2007, Stan collapsed while playing basketball. Heart tests showed that he had right ventricular dysplasia, which is the leading cause of death for athletes. Because this heart disease may be hereditary, doctors believe that other members of their family are also at risk for heart disease. Stan and his brother were found to have familial cardiomyopathy, which affects the heart muscle. Some people with cardiomyopathy—especially those with hypertrophic cardiomyopathy—may live a healthy life with only a few problems or symptoms. But others may have serious symptoms and complications. As the heart ages, it becomes more difficult to draw blood from the entire body and maintain a normal electrical rhythm. The surgeon implanted a defibrillator to help regulate Stein's heart rhythm. His heart disease worsens and becomes cardiogenic shock, which can be fatal if not treated in time. On November 7, the doctor removed his failing heart and implanted a temporary artificial heart of Xinkadia . Stan's artificial heart was originally connected to the Big Blue drive. With the FDA approved free drive in 2014, he switched to being driven freely while waiting for a heart transplant . The move marks two milestones: the first case was transferred to a US Michigan patient using a free-drive artificial heart, and the first in Michigan to carry a free-drive home to recuperate. Dominique Larkin also needs an artificial heart. He is still in the intensive care unit of the Frankel Cardiovascular Center at the University of Michigan, with a heart connected to Big Blue. The doctor is determining his next best treatment for this severe heart failure. The artificial heart is only a temporary treatment for the brothers in the long heart transplant waiting process. Currently, more than 3,000 patients in the United States are waiting for a heart transplant. "He said he is proud of me," said Stan, who works closely with professional and physiotherapists. He is now free to drive freely. You can't stay away from the power supply, eat foods with low sodium content, and take a series of drugs that dilute blood is the rule he must follow .
