Heart valve Essays

Tissue or Mechanical, when choosing heart valve for replacement should age of a patient play a role in the selection? Before giving my opinion, about if the age of a patient play a role in selection of a valve replacement, I will first discuss the different between Tissue and Mechanical valves. Tissue heart valves: A lifetime of a tissue valve is typically 10-15 years, and are often less in younger patient. Tissue valves without frames improve blood flow. Tissue valve are not easy to put in place and

Based on the anatomy of the heart, heart tissue, and the heart valves, certain material specifications need to be taken into consideration to ensure that artificial heart valves function like normal healthy heart valves. When one of the four heart valves can no longer function sufficiently it may need to be replaced with an artificial heart valve. There are two main types of artificial heart valves: mechanical, and biological. Mechanical heart valves can be grouped by their method of implantation;

Bioprosthetic valves used in heart valve replacement generally offer functional properties that are more similar to those of native valves. Implantation of prosthetic cardiac valves to treat hemodynamically significant aortic or mitral valve disease has become increasingly common. Replacement of diseased valves with prosthetic heart valves reduces the morbidity and mortality associated with native valvular disease, but it comes at the expense of risking complications related to the implanted prosthetic

Heart valve disease refers to the condition wherein one or more of the heart’s valves suffers from a dysfunction. These valves include the four valves of the heart which are known as the tricuspid valve, the pulmonary valve, the mitral valve, and the aortic valve. The heart’s valves are essential in the process of blood flow to and from the heart and a problem of any of these valves may cause a problem in the circulation of blood throughout the body. What are the types of heart valve disease?

30% of mortalities. Heart valve diseases are life threatening affecting ~2.5% of the general population in economically developed countries (V.T. Nkomo et al. 2006). Approximately 100,000 heart valve replacements are performed each year in the U.S. It is estimated that patients requiring heart valve replacements will be tripled from 290,000 in 2003 to 850,000 by 2050 (Yacoub and Takkenberg 2005). It is estimated that 5 million patients in India are suffering from heart valve disease and every year

Here’s a cool trick: if you have a leaky copper pipe, you can use a piece of white bread to repair it. You want to cut off your mains and drain your lines to get rid of any water leaking from the pipe you’re trying to sweat. Sometimes, a shop vac works in getting any extra water out. But sometimes it doesn’t, and you’re stuck with an annoying drip that makes a proper solder nearly impossible because boiling hot water is coming through a seam and it doesn’t let the solder set where it should. There’s

Julie Maldonado BA406-01 Professor Filomena Cantoria Chapter 1 WAC #1: Bhopal-Union Carbide Background The Bhopal-Union Carbide case occurred in India where approximately 2,000 led to deaths and 200,000 resulted in injuries on the nights of December 2 and 3 in the year of 1984. The source of these loss and damages was from the deadly methyl isocyanate gas that leaked from the Union Carbide plant which was an inflammable toxic chemical utilized to produce pesticides. Unfortunately, the small huts

1.1 Internal Combustion Engine Heat engine are produced from internal combustion engine which converts chemical energy in a fuel into mechanical energy and actually available on a rotating output shaft. Thermal energy is produced from the conversion of chemical energy of the fuel to the thermal energy by means of combustion or oxidation with air inside the engine. The temperature and pressure of the gases within the engine is raised by thermal energy and the high pressure gas then expands against

The pylon is the internal frame or skeleton of the prosthetic limb. The pylon must provide structural support and has traditionally been formed of metal rods. In more recent times, lighter carbon-fiber composites have been used to form the pylons. The pylons are sometimes enclosed by a cover, typically made from a foam-like material. The cover can be shaped and colored to match the recipient's skin tone to give the prosthetic limb a more lifelike appearance. The socket is the portion of the prosthetic

When I was a child, I would go into my dad 's tool box and grab some tools to take apart my toys. I would have to admit that I was a curious little kid and took my toys apart just to see what the parts inside did to help move the toy. I would always get into trouble because my parents would find things disassembled and go to me as the source of the problem. Even when I had school, on the weekends I would take my pedal bike apart because I would need to adjust the handlebars, or change the height

How A Thermal Imaging Camera Helps Your Plumber Find A Water Leak In Your Home One of the most frustrating things about a water leak in your home is that the leak can go undetected for months. If the leak is small, it might not cause a huge difference in your water bill, yet your home is being damaged by water all that time. What's worse is developing a large leak that makes your water bill skyrocket, yet you can't even figure out where the water is leaking. A plumber can locate a hidden water leak

On a hot summer day, boiling hot tap water is not as refreshing as fresh, cold bottled water. Ever since the beginning of time, water has always been an imperative part of our lives for hydration. Even though, it is an important source of hydration, tap water is not as good as bottled water. Water fountains are often neglected by cleaning staff, you can find gross things which makes the tap water dirtier than bottled water. Also, we have to worry about pipe problems, the pipes of the water fountain

The first bileaflet valves were introduced in 1978. The bileaflet valve is one of the most impactful biomedical discoveries of the past 30 years. One of the main reasons why bileaflet valves were developed was to prevent calcification that was prevalent in the previous mechanical valves. Calcification occurs when calcium deposits stick to the valve flaps which hinders the movement of the valve and the ability to allow fluid to move back in the atrium or ventricle that it originally came from. The

Mitral valve regurgitation is one of the few heart conditions you may unknowingly have for years and learn to live with the affects of this condition before ever being diagnosed. Mitral valve regurgitation occurs when the mitral valve is letting blood leak backward into the upper chambers of the heart. The mitral valve is located between your heart’s two left chambers . Mitral valve regurgitation, or mitral insufficiency as it is known, is a common heart valve disorder. It is a disorder affecting

‘The Tiger’s Wife’ By TÉA OBREHT 1: The Coast The forty days of the soul begin on the morning after death. That first night, before its forty days begin, the soul lies still against sweated-on pillows and watches the living fold the hands and close the eyes, choke the room with smoke and silence to keep the new soul from the doors and the windows and the cracks in the floor so that it does not run out of the house like a river. The living know that, at daybreak, the soul will leave them and make

The mitral valve, which is also sometimes referred to as the bicuspid valve, is one of the four cardiac valves1 in the heart, located beneath the left atrium and above the left ventricle (Figure 1), preventing backflow of blood between these two chambers of the heart. The word mitral comes from the latin word mitra which translates as a turban or belt2. Figure 1 Diagram showing where the heart chambers, blood vessels and valves are located3 Figure 2 Cross section of the heart, showing

Introduction of a Flexible Polymeric Heart Valve Prosthesis with Special Design for Mitral Position Layman-friendly summary: The traditional method to replace the damaged heart valve is using mechanical valve or biological valve. Mechanical valve can be last long but blood-thinning medicines need to be taken for the rest of the person’s life to prevent blood clotting around where the mechanical valve placed. Heart valve prostheses are introduced with The mitral valve lies between the left atrium and

The heart is a vital organ, which pumps blood around the body which allows all of the cells and organs in the body to receive oxygen and nutrients that they require to function. It is a part of the cardiovascular system which also includes the blood vessels and veins. Within the heart, there are four chambers – two atria and two ventricles- and between each chamber there is a valve which blood flows through as it leaves the chamber. Valves have the physiological role of preventing blood flowing
