Step into the fascinating realm where human ingenuity meets life-saving innovation – the realm of artificial hearts. Imagine a beating heart crafted not by nature, but by human hands, pulsating with the promise of second chances.
Now the question is how it works.
The complete mechanical heart features four mechanical valves functioning similarly to the heart’s own valves, effectively regulating the circulation of blood. These valves link the device to the heart’s upper chambers known as atria, as well as to essential arteries such as the pulmonary artery and the aorta. Once this mechanical heart is connected, it takes on the role of a healthy heart, enabling the seamless flow of blood throughout the body.
Here, you will discover more and how to take care of an artificial heart.
What Is Total Artificial Heart?
Functioning as a mechanical substitute, a total artificial heart (TAH) steps in when your heart’s functionality falters. Placed within your chest by a skilled heart surgeon, this innovative device takes over the role of damaged or ailing heart ventricles.
Moreover, The ventricles, those crucial lower heart chambers, comprise a left and a right component. Upon receiving a total artificial heart, both these ventricles find their replacement. Thus, the TAH adeptly fulfills the functions that the ventricles, in their compromised state, can no longer execute.
In addition, Sustained by an external, portable machine, the artificial heart maintains a consistent rhythmic pump. This vital power source resides outside your body and ensures the device’s uninterrupted function.
An essential component, known as the driveline, connects the TAH to the external apparatus, emerging through the abdomen’s skin. Similarly, This seamless integration serves as a testament to medical ingenuity, facilitating a life-sustaining connection that fuels the artificial heart’s performance.
How do artificial hearts work?
Pumping Apparatus: Artificial hearts encompass a pumping apparatus that mirrors the rhythmic pumping action of a natural heart. Typically, this involves the presence of one or more chambers, akin to the heart’s ventricles, responsible for initiating blood flow.
Blood Circulation: Deoxygenated blood from the patient’s body enters the substitute heart’s inflow chamber, frequently by a connection to the patient’s natural heart or major blood veins.
Pulsatile Propulsion: The mechanical pumping mechanism emulates the heart’s contractions and relaxations, generating the requisite pressure that propels oxygen-rich blood into the outflow chamber.
Oxygen Enrichment: The oxygenated blood is then efficiently pumped into the body’s primary arteries, facilitating the smooth dispersion of vital nutrients and oxygen to organs and tissues.
Regulation and Oversight: Many modern mechanical hearts have complex control systems that carefully control pumping rates and pressure, easily adjusting to the individual physiological requirements of each patient.
Energy Source: The operation of artificial hearts is frequently sustained by external sources of energy, encompassing battery packs or electrical connections. In certain instances, these devices are meticulously engineered for portability, offering patients increased mobility and autonomy.
