| | Heart-lung machine 50th anniversary marked: 5/2 |
 | | The health care professionals who operate heart-lung machines under the direction of a cardiac surgeon are known as perfusionists. | | | As a result, nearly 800,000 people around the world undergo heart surgery a year while supported by the modern version of the heart-lung machine. | | | For 27 minutes during the operation, her heart and lung functions were completely maintained by the machine. |

| | During open-heart surgery, such as a bypass procedure, a machine takes over the function of both heart and lungs. | | | This heart-lung machine allows the surgeon to carefully stop the heart, while the vital organs continue to receive blood and oxygen. | | | The nondisposable hardware portion of the heart lung machine is called the pump console and directly manages this circuit. |

| | During an open-heart surgery, such as bypass surgery, the heart-lung machine takes over the functions of the heart and lungs and allows a surgeon to carefully stop the heart while the rest of the patients body continues to receive oxygen-rich blood. | | | His first experimental machine used two roller pumps and was designed to replace the heart and lung action of a cat. | | | Before its introduction to medicine in the 1950s, heart surgery was unheard of; there was no way to keep a patient alive while working on the heart. |

| | The Mechanical Heart celebrates 50 lifesaving years |
| | Like classic automobiles, the heart-lung machine has a life of its own, says Larry Stephenson, M.D., professor of cardio-thoracic surgery at Wayne State University School of Medicine and a medical historian. “Although new technologies continue to be developed to correct heart problems, for the foreseeable future the heart-lung machine is the mainstay for cardiac surgeons.” | | | Their efforts, funded in part by the American Heart Association, revolutionized cardiac surgery when doctors in 1952 used the Dodrill-GMR (General Motors Research) Heart Machine to perform the first “open heart” surgery to save a man’s life. | | | The American Heart Association is helping fund current research to support new techniques being developed in the area. |

| | Open heart surgery is possible because medical research developed the heart lung machine to bypass the heart and lungs, taking over both the pumping of the blood and its oxygenation. | | | Subsequent experiments by Melrose6 and David Hearse7, using the isolated hearts of rabbits and rats, established optimum concentrations of potassium chloride to stop the heart, and ways of preserving the heart while starved of blood. | | | Under these conditions the heart can be operated on for many hours, and delicate procedures such as heart valve replacements can be performed. |

| | During the operation, a heart-lung machine continuously moves oxygen-depleted blood out of your circulation and returns oxygen-rich blood, performing the functions of the heart and lungs. | | | You have debilitating angina, or chest pain, because several of the arteries that supply your heart muscle are narrowed, leaving the muscle short of blood. | | | Coronary bypass surgery is one of the most common and effective procedures to manage blockage of blood to the heart muscle. |

| | Minimally Invasive Heart Bypass Procedure Found Effective |
| | Conventional coronary artery bypass surgery requires that the sternum -- or breastbone -- be cracked and separated, the heart stopped and blood circulated through the body by a heart lung machine. | | | While surgeons first began operating on beating hearts in the late 1980s to eliminate the need for and risks associated with heart lung machines, separation of the breastbone was still necessary. | | | Often referred to as "keyhole" heart bypass surgery, the relatively new procedure holds the promise of lower hospital costs, less pain and a faster recovery, said Magovern who is also an associate professor of surgery at Allegheny University of the Health Sciences. |

| | Most traditional bypass surgeries involve connecting a patient to a heart-lung machine which substitutes for the patients own heart and lungs and allows surgeons to stop the heart from beating while they perform delicate surgery on its blood vessels. | | | But, some health care experts say that heart-lung machines place patients at risk for potentially fatal complications such as stroke, abnormal rhythms, lung problems, and fluid retention. | | | Suction cups attach to the heart muscle on either side of the artery on which the surgeons operate. |
