Artificial heart valve

Coronary heart disease, one of the most pervasive disease, has influenced more than million individuals around the globe. It has brought biomedical engineers and scientists closer to develop devices like defibrillators and artificial hearts that may alleviate patients’ pain. As the number of patients suffering from heart diseases increase, the need for donor hearts increases as well. In 1995, 4000 patients waited for donor hearts and 731 of them died waiting (ijates.com). Artificial hearts…

Interventional cardiology is a relatively new field in medicine. The doctors within this field treat heart diseases through minimally invasive procedures through the use of catheters, stents, and balloons. Catheter are thin tube made up of several types of material depending on how it will be used. A stent on the other hand is a tube composed of metal that can remain within the body to keep a blood vessel open. Interventional cardiology is said to be first discovered by Andreas Gruentzig in…

body systems? The artificial heart supports the role of a heart because an artificial heart supports the heart by helping it pump necessary blood and oxygen around the body in order for the body to properly function. Why is the device needed? The artificial heart is needed if you have severe heart failure and your heart cannot pump enough blood around the body in order for the body to function properly. Severe heart failures are commonly caused by diseases, infections or heart attacks. People…

everything they need, the heart needs to be beating. The cardiovascular system makes sure the levels of substances in the blood is constant by transporting these substances as circumstances change. The heart is located in the lower part of the mediastinum between the lungs. Most people think the heart lies on the left side of the body but if the chest was cut in half, two thirds of the heart would be on the left and one third would actually be on the right side of the body. The heart is…

An artificial heart is an invention that is saving many lives worldwide. The idea was created by Paul Winchell and later changes by Robert Jarvik. The artificial heart is ran by a pacemaker, and if only two chambers are working you will need an artificial heart pump. There are many risks and disadvantages to living and having an artificial heart. Making the heart is very complex and takes a while to make. Also in the medical field, artificial hearts are useful because they help people live…

People who have Endocarditis will have inflammation of the inner walls of the heart mainly in the heart valves. This can also infect artificial heart valves, pacemakers, or implantable defibrillators. Endocarditis infection is most commonly found in people with preexisting heart diseases. To get this infection the bacteria will enter the bloodstream and attach to damaged places of the inner parts of the heart, but not all the bacteria entering the bloodstream will cause this infection. If this…

2.1. The left ventricle and interventricular septum The heart has two inferior chambers, called the right and left ventricles, respectively. These chambers are the “pumps” that expel blood into the blood vessels and keeps it flowing through the body (Rizzo, 2016). The left ventricle is a cavity that has thick muscular walls that contains the papillary muscles as well as the chordae tendinae that attaches the atrio-ventricular valve leaflets to the papillary muscles (Leeson, Augustine,…

Until recently, the only viable option for severe heart failure patients has been heart transplantation. Heart disease continues to claim an increasing proportion of the world’s population, so in turn the demand for donor hearts is rising. However, according to the alarming figures from the Registry of the International Society for Heart and Lung Transplantation in 2013, the number of donor hearts readily available for transplant are flat in countries and declining in others. To address this…

cardiovascular function and lead to increased risk of cardiovascular disease, even in healthy asymptomatic individuals. Heart attacks and strokes are usually acute events and are mainly caused by a blockage that prevents blood from flowing to the heart or brain. The most common reason for this is a build-up of fatty deposits on the inner walls of the blood vessels that supply the heart or brain. Strokes can also be caused by bleeding…

A prosthetic device in substitution of a heart that is usually used to create more time of life until a transplant can be performed, also known as an artificial heart. An artificial heart creates more time to a heart transplant but it can also be a permanent substitution of the biological one. An artificial heart is very hard to receive, a patient must seriously be ill or about to die before it can even be considered. It is a very costly procedure and the whole transplant itself is very…
