LVAD (HeartMate II)
Negative
Effects on humans?
The risks that come along with the LVAD are blood clots, bleeding, infection, device malfunction and right heart failure.
Blood clots:
Throughout your body as the blood is flowing through the LVAD blood clots can be formed. Blood clots slow and or block the flow of your blood that flows towards your heart. This could either cause a heart attack, stroke or your LVAD to stop working. If this does happen you would then be prescribed blood thinning medication and would have to come for regular blood tests. This would be to monitor the effects of the blood thinning medication.
Bleeding:
The LVAD is placed through an open heart surgery. Open heart surgery will increase the amount of bleeding during the time of your surgery and after. If you do take medication for blood thinning this can increase the risk of bleeding into the gastrointestinal tract and to the brain
Infection: Since the battery and the controls of the LVAD are connected through a wire outside your body there is a higher changed os germs getting stuck in the port. This could then lead to infections that are very surveyor.
Device malfunctions:
Your LVAD could stop working for many reasons. One of them could be that the pumping of the LVAD is not working properly, this then leads to not enough blood pumping through to your heart. Also, the battery of the LVAD could stop working or the other parts of the LVAD could stop functioning properly. All of these problems lead to immediate medical attention.
Right heart failure: When you have a LVAD placed it leads to more blood being pumped from your left ventricle of your heart. Your heart is not used to this happening thus causing your right ventricle to become weak to pump the amount of blood the other side is pumping. This could then lead to the right part of your heart to fail. If this does happen critical medication attention is needed or an RVAD could be placed to support the right ventricle.
When you have the LVAD placed in you must always carry a battery around your shoulders, whenever and wherever you are. Researches have made the battery/power source much smaller but it is reliably heavy. Due to carrying such a heavy battery this could lead to other problems.
When you have the LVAD placed in, you can not go swimming or go under water at all. There are special wrappings/covers that are created for when you want to take a shower.
Positive
Effects on humans?
The LVAD helps patients who are ineligible for heart transplants, who have had a heart failure or are waiting for a heart transplant.
It gives patients who are ineligible for a heart transplant a longer life span. It tends there life for two years or even longer than that and lets the patients live in ease
Before when patients where on list for a heart transplant and were waiting to find a heart that matches they didnt have a device in which could support their heart for as long as they couldn't find a heart. Many of these patients would then later on die due to their heart not being able to support them. With the LVAD, patients who are waiting for a heart that matches, LVAD's are placed to help support their heart in the mean time. This then could even lead to your heart improving and functioning back to normal.
Neutral
Effects on humans?
-
It allows researchers to expand their knowledge about the heart and how to improve upon the LVAD. Also, it allows researchers to go beyond the heart and learn about creating other devices in which can help other organs. In addition to that, since the researchers have the confidence and knowledge of how to create devices in which can help other organs in your body

5 W's
Who
The LVAD was created and designed by Domingo Liotta during 1962. He attended Baylor College of Medicine in Houston and created a milestone in the history for heart surgery.
-
Why
It was created to help patients who are ineligible for a heart transplant, who either have a heart failure or are waiting for a heart transplant. LVAD’s were created to help a patient for a temporary time until a heart could be found. Also known as bridge to transplant
What/How does it work?
The LVAD (left vertical system) is a pump used on patients who are ineligible for heart transplant, either who have a heart failure or are waiting for a heart transplant. The LVAD is surgically implanted and is a battery operated mechanical pump. The LVAD takes blood from your left ventricle (central pumping chamber) and pumps blood and spread it to other places in your body

How is it implanted?
The LVAD is placed in a person adenines, in which routes oxygenated blood to where you want it to go. It then takes this oxygenated blood from your heart then to the rest of your body (spreads it). In simple words, the LVAD is placed in to take blood from your heart and pump it across your body.
