The Artificial Heart

scientific histroy

The AbioCor self-contained artificial heart, which was first implanted into a patient on July 3, 2001. The outer shell is polycarbonate, and the valves and inner bladder are polyurethane.


Artificial hearts

The heart is an organ that pumps blood around the body system. It has four different chambers:
The left and right atrium (this is a chamber for receiving blood). The left and right ventricles (the chamber that pumps blood).
Blood in the right ventricle (right part of the heart) is pumped into the pulmonary artery and on to the lungs.
Blood in the left ventricle (left part of the heart) is pumped into the aorta and through to the body.

Blood from the body enters through the superior vena cava (SVC) and the inferior vena cava (IVC) into the right atrium (RA). It then passes through the right atrium into the right ventricle (RV) and is subsequently pumped through the pulmonary artery (PA) into your lungs.
In the lungs, blood is enriched with oxygen and carbon dioxide is expelled from it.
Blood from your lungs is received through the left atrium (LA) and passes into the left ventricle (LV) from where it is pumped through the aorta into your body.
It supplies oxygen and nutrients to the many cells in your body.
When your heart is not pumping enough blood around the body because your heart is severely failing, an artificial heart may be needed.

The artificial heart

This is a mechanical gadget, about the size of a fist that is associated with the heart or embedded in the chest to help a deteriorating heart. It might have a few valves, an instrument to push blood forward, and at least one chamber.

Once in a while, an artificial heart may help your heart briefly, until it recuperates. If so the artificial heart will be removed when it is not required again.

Moreover, when there are irreversible heart muscle defects and the heart can't recuperate, the artificial heart remains until you can undergo a heart transplant. In the event that no different alternatives are accessible, an artificial heart may totally and forever replace the heart.

Types of the artificial heart

An artificial heart that gives an additional ventricle (pumping chamber in the heart) to move blood around the body. This is known as a ventricular assist device (VAD).
A VAD is produced using metal and plastic and has a little pumping chamber lined by an astonishing material that prevents blood from clotting.
It might be put into your body or lie outside your body, based on the kind of artificial heart that is utilized.
A VAD might be linked with the heart in different routes in the event that it needs to bolster the left half of your heart, the correct side of your heart or both sides of your heart.
If it needs to support the left half of the heart, it is connected to one side chamber/ventricle and the aorta and is known as a left ventricular assist device (LVAD).
Blood is gotten into the gadget from the left ventricle (LV) and is drawn into the aorta.
If it needs to bolster the right part of the heart, it is joined to the right artery and pulmonary artery, and it’s known as the right ventricular assist device (RVAD).
Blood is gotten into the gadget from the right atrium (RA) and is directed into the pulmonary artery (PA).
In the event that it needs to support both sides of your heart, it is connected in both of the above ways and is known as a bi-ventricular assist device (BiVAD).
This is a mix of a left ventricular assist gadget (LVAD) and a privilege ventricular assist device (RVAD).
In the event that it needs to support the right side of your heart, it is joined to the right atrium and pulmonary artery and is known as a right ventricular assist device (RVAD).
Blood is gotten into the gadget from the right atrium (RA) and is directed into the pulmonary artery (PA).
In the event that it needs to support both sides of your heart, it is connected in both of the above ways and is known as a bi-ventricular assist device (BiVAD).
This is a mix of a left ventricular assist gadget (LVAD) and a privilege ventricular assist device (RVAD).

How does a simulated heart function?

Blood enters the artificial heart via the left or right chamber (the chamber that receives blood). It is then pumped into the aorta (the artery connected to the body) pulmonary artery (the artery connected to the lungs), dependent upon which side of your heart is being bolstered.
An artificial heart is power-driven by either packed air or power. A thin link interfaces the pumping chamber to a control the system (console) that manages the pump actions. The control system can be a substantial box on wheels that stays close to the individual, moving with you when you walk around the healing facility.
It can likewise be significantly littler, with removable batteries, and worn on a belt or vest.
The littler support gives you more opportunity and versatility than the huge system (console) and may make it likely for you to leave health facility.

How long does an artificial heart last?

Before you get a heart transplant, the artificial heart will continuing working until you have the transplant. These can extend from half a month to over one year.

In the event that you require an artificial heart for all time since you are not suitable for a heart transplant, an artificial heart may keep going for quite a long while.

Animals, including humans, generate heat, even at rest, due to their metabolic activity. Some of this heat is lost to the environment by radiation, convection, conduction,and in terrestrial animals the vaporization of water. Evaporation has a significant cooling effect because about 2.5 kJ of heat is given up for every gram (ml) of water lost
