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…

heart through the pulmonary artery to the lungs and to the left side of the heart then back out to the rest of the body with oxygenated blood and the cycle repeats. In TGA, deoxygenated blood returning are not going to the lungs to be oxygenated, but is pumped back out to the body. This happens because…

right ventricle, left atrium and the left ventricle. The right atrium is the chamber which receives blood from the body that has been depleted from its oxygen and pumps it to the right ventricle. The right ventricle then pumps the blood from the right atrium over to the pulmonary artery which as the name would suggest means it goes to the lungs and the oxygen depleted blood is once again oxygenated. The left atrium of the heart then receives the blood that has been oxygenated to the left…

the article, Caffeine Improves Left Hemisphere Processing of Positive Words written by Lars Kuchinke and Vanessa Lux (2012) hypothesized the “link between the left hemisphere (LH) will have a positive advantage in emotional word recognition” (p. 2). The increased dopamine in the brain and caffeine administered is anticipated to increase word recognition by enhancing the process of positive words by the effects of caffeine. This study help others’ understand how the left hemisphere processes and…

Mitral Valve Stenosis Mitral valve stenosis is a narrowing of the mitral valve. This is the valve between the upper chamber (atrium) and lower chamber (ventricle) of the left side of the heart. Mitral valve stenosis is often discovered when your health care provider hears an abnormal sound (heart murmur) while listening to your heart. This condition can range from mild to severe. CAUSES This condition is caused by: • Rheumatic fever, which is a complication of strep infection. • Buildup of…

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…

abundance of threes. When looking at the Justinian Mosaic it can be separated into three quadrants. On the left side there are soldiers and court officials, in the middle there is Justinian and on the right side, the representatives of the church are shown. In Theodora 's mosaic her mosaic can be seperated into quadrants of three is as well.
