Creating Artificial Heart Research

In this experiment, the external and internal structures of a sheep’s heart was examined and identified by dissection. To determine the functionality of a human heart since they are both mammals.

A 30cm piece of thread was placed around the heart at the Atrioventricular groove (AV groove) and tied in a knot but left loose so as to not interrupt the normal function of the heart. The heart was allowed to beat for about 15 seconds with no pressure. After 15 seconds the knot was slowly tightened while taking care to stay on the AV groove while tightening. Data was observed and recorded.

I am working on becoming a cardiovascular technologist in pediatrics. There are many reasons why I have chosen this field. First, I think that working with children is so much different than working with adults. Mostly, the children that will be seen in cardiac offices are going to be children that have congenital heart disease; meaning that they were born with deformations that developed in utero. They can range from being a very sick and fragile child to a child that only had to receive a routine repair. I would like to be the person that works with a sonographic or echocardiograph machine. I will be doing scans of these children’s cardiac anatomy and mapping out the 3D model that the cardiac / thoracic surgeons need to do surgery correctly and safely. Another reason that I would like to work in pediatrics and not adults is because children have not done anything to trash their bodies. They are not dying from cholesterol blockages and drug overdoses or heart and lung disease from smoking. Children are so pure and have done nothing to their bodies. Every heart that I am going to be working with is going to be unique. Meaning that every heart will have its own deformations. I find this fascinating. Lastly, I want to work in this field because I lost my son four months ago because his cardiovascular map wasn’t investigated as much as it obviously should have been. He was born with a very complex anatomy. He died from a preventable surgical

Organ donation provided a new therapeutic path when new drugs and devices failed to reduce the mortality and morbidity rate of patients with such illnesses as cardiovascular diseases. By replacing damaged organs or tissue with a functioning substitute, organ transplantation offers an immediate cure. Unfortunately, this “cure” is never guaranteed because of the high risk of graft rejection and that’s if a suitable donor can be found. Thus, tissue engineering has been the projected new treatment for these problems. Tissue engineering replaces the diseased or damaged tissue or organs with biofabricated counterparts made using the specifications dictated by the features of the specific tissue or organ.

TROPONINS – Markers of choice. Elevated between 4 and 6 hours after the onset of an acute MI and remains elevated for 8-12 days.

John Gibbon. (Bruno 379). Then In 1953 John Gibbson performed the first successful operation on a heart using the heart and lung machine. The patient Cecilia Bavolek, who was connected to the machine for 45 minutes. (“History of the heart and lung machine”). The technique still had a major flaw, the heart was left beating during the surgery while blood still reaching it, this made it messy and difficult to operate on. (“History”).The first heart and lung machine was built by physician John Heysham Gibbon (“Heart and lung machine”). The first 4 procedures that gibbon performed were unsuccessful and all four patients died. This device minimized haemolysis and prevented air bubbles from entering circulation (“Heart”). In other words, this device temporarily takes over the function of the heart and lungs while the patient's heart is being worked on.The heart and lung bypass machine was first used on a human in 1953, but however, it was not considered safe for use until 1960 (“Heart”). The heart and lung machine cured most cardiovascular

There are two types of artificial hearts, the first being a pump that is connected to the patient’s circulatory system; it maintains life when the patient’s heart is stopped for the surgeons to be able to operate on the heart. The second type is a self-contained mechanical heart that sits completely in the patient’s chest cavity. This second type of heart is known as a “VAD” pump which pumps blood from the left ventricle to the aorta. Most mechanical hearts use a centrifugal pump, which is quieter, uses less energy and lasts longer than the piston type mechanical hearts. The centrifugal pump produces a constant flow of blood around the body; therefore the patient will not have a

"A Simple Heart" had been written in 1887. Except for the environment, the objectification of women, relegated to a mere source of males' satisfaction, as depicted in these verses, is still a plague. Yes, a plague. We are beaten, humiliated, brutalized daily, in every part of the planet.. I can quote personal experience, but I am not going to bother you. I would like to know why a woman free of express herself is not considered a "wedding commodity"? Hypocrites! Scraping the bottom of the barrel is a typical male

The stem cells were engineered from typical skin cells. This technique means that heart patients would not have to worry about rejection. Their new hearts would be made of their own cells.

The students will apply their knowledge about the heart to a design—in which the heart will be modeled as a pump.

It is expected that the new "virtual heart" could help in the development of new medicines to treat the condition.

Almost 80% of people die from heart disease. The only way to know your level of risk is to be assessed by a healthcare professional and to be checked for factors such as your blood pressure, cholesterol and glucose levels, waist measurement and BMI. Once you know your overall risk, agree with your healthcare professional on a plan for specific actions you should take to reduce your risk for heart disease and stroke. The Circulatory System is made up of three main parts: The heart, the blood vessels and the blood. Sometimes the watery fluid called lymph and the vessels that carry it are considered to be part of the Circulatory System. The heart is a special pump that pumps the blood around the body. The purpose of this paper was to summarize information about the heart, explain how it works, and discuss its purpose. It was said that the heart evolves through several different stages inside the womb, first resembling a fish's heart, then a frog's, which has two chambers, than a snake's, with three, before finally adopting the four-chambered structure of the human heart. I also told you how the heart works. When the heart contracts, the chambers become smaller, forcing blood first out of the atria into the ventricles, then from each ventricle into a large blood vessel connected to the top of the heart. Now the purpose of the heart is the size of its owner's clenched fist, the organ sits in the middle of the chest, behind 1the breastbone and between the lungs, in a moistened chamber that is protected all round by the rib cage. It can also be easy to fix the heart. The only way to know your level of risk is to be assessed by a healthcare professional and to be checked for factors such as your blood pressure, cholesterol and glucose levels, waist measurement and BMI. The heart is very important for your

On January, 2008, Doris Taylor, director, Center for Cardiovascular Repair, University of Minnesota used the core procedure of decellularisation to let hearts from animal cadavers beat by infusing live cells. The research
