Coronary heart disease, one of the most pervasive diseases, has influenced millions of individuals around the globe. In 1995, 4000 patients waited for donor hearts and 731 of them died waiting (ijates). As the number of patients suffering from heart disease increased, the demand for donor hearts increased along with it. For this reason, it has brought biomedical engineers and researchers closer to developing devices like defibrillators and artificial hearts that may alleviate patients’ pain. Artificial heart transplant machines are now reliable treatment options for heart failure. These machines are utilized as a substitute until a donor organ can be found. Statistics show that this method has resulted in an improvement of survival rate of 80% (Martin Struber). Although artificial hearts are costly and potentially life threatening, it is conceivable that these machines may have a more prominent part to play as their expenses diminish and technological improvements expand dependability.…show more content…
The design of these hearts is close to the structure of the natural heart. The heart that humans carry has two pumps and four chambers. The right atrium gathers oxygen-drained blood and pumps it to the lungs. The left atrium receives oxygen-rich blood from the lungs to and pumps this blood out of the body. The valves’ function is to control the blood flow (Raghunandan Avula). On the other hand, artificial heart has three subsystems placed under the skin. These subsystems are the heart pump, a pump controller, and a power source. The battery of the heart is charged with a special magnetic charger. Energy from the external charger is transferred to internal battery through an energy transfer device known as transcutaneous energy transmission (National Heart, Lung, and Blood
