Tricuspid valve

Mechanical Heart valves are designed to mimic natural heart valves as closely as possible. The valve is implanted in the heart of the patient where the damaged heart valve was removed. Artificial heart valves allows for correct blood flow through the heart by opening and closing with each heartbeat (St Jude Medical, n.d.). The Medtronic mechanical heart valve contains two leaflets (Medtronic, 2011). The pressure in the heart causes the leaflets to open and close, allowing blood flow in only…

and Biocompatibility of the Carpentier Edwards Magna Ease Aortic Heart Valve Chelsea Gibbs University of Utah Statement of Purpose: This report will look at the biomaterials used in the Carpentier-Edwards Perimount Magna Ease Aortic Heart Valve (CEPME) (Edwards Lifesciences LLC, Irvine, CA) and some of the biocompatibility issues found with this device. The CEPME bioprosthesis is designed to replace a diseased aortic heart valve that is no longer functioning properly and the tissue cannot be…

Visual Prosthesis: Selling a Dream to Visually Impaired (A literature review of advancements in the field of Visual Prosthesis) Abstract Visual prosthesis is by far the best bet to restore vision in a patient suffering with visual loss. This paper provides a literature review of the various technological advancements made over time and how these advancements have proved noteworthy in fields of visual prosthesis. To develop a basic understanding about the visual prosthesis, the anatomy and…

Mechanical heart valves provide their greatest benefit by replacing a fatigued natural valve with a prosthesis that was specifically engineered for the variety of patients who experience heart valve disease, thus relieving the patient of most associated conditions and improving their quality of life. However, throughout the last half century there have been many cases of structural failure and induced conditions such as thrombosis due to the materials used in these devices. Through the many case…

The Edwards SAPIEN heart valve is a collapsible aortic heart valve that can be introduced into the body via a catheter-based delivery system. The valve is designed to replace a patient’s diseased aortic valve without traditional open-heart surgery and while the heart continues to beat. The valve can be implanted in patients using the fransfemoral technique meaning delivered thorough the femoral artery or trans-apical technique meaning delivered via a small incision between the ribs. Prior to…

Researching for life’s improvements is the goal for every engineer, this explains the countless hours engineers spend inside an office or a laboratory. Although people think of engineers as only creators of lifeless technology, many of biomedical engineers specialized in technology for the living. Meeting between medicine and engineering, biomedical engineers find solutions for medicine and, in some cases, people’s disabilities. These disabilities appear from accidents in the workplace to war…

They are both comprised of cardiac muscles which contract involuntarily to pump blood. Each side of the heart contains valves which prevent the regurgitation of blood. The left and right side of the heart have a mutual muscular segment by which they are separated and is known as the atrioventricular septum. Differences between Left and Right Side of the Heart? • Left side…

to beat at a normal rate. There are four valves in the heart which prevents the backflow of blood. They are the bicuspid valve, tricuspid valve, aortic semilunar valve and the pulmonary semilunar valve. The bicuspid valve is located between the left atrium and ventricle. The tricuspid valve is located between the right atrium and ventricle. The aortic semilunar valve is located between the left ventricle and the aorta and the pulmonary semilunar valve is located between the right ventricle…

the thoracic surface do you auscultate to the tricuspid, mitral (bicuspid), pulmonary, and aortic valves? The tricuspid valve is between the right atria and right ventricle. Therefore, you would auscultate the tricuspid valve on the left side of the heart, between the fourth and fifth rib (or intercostal space) and lower left sternum area. The mitral valve is between the left atrium and left ventricle. Therefore, you would auscultate the mitral valve on the right side of the heart, between the…

is the stage where ventricles begin contracting, the aortic and semilunar valves close which prevents a change in volume. The fourth stage, ventricular ejection, is the moment where the ventricles are emptying themselves through contractions. The final stage is called the isovolumic relaxation time, during this stage pressure decreases, no blood enters the ventricles, the ventricles then begin relaxing and the semilunar valves close due to pressure of blood found in the aorta. The heart also…
