Mitral valve

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…

The Anatomy of the Mitral Valve The mitral valve, also called the left bicuspid atrioventricular valve, is located in the left side of the heart between the left atrium and the left ventricle. In relation to the sternum, the mitral valve is positioned posteriorly and is at the height of the 4th costal cartilage of the rib cage (Moore, Dalley and Agur, 2014). The valve is composed of two cusps, the anterior and the posterior cusps, which are held in place by chordae tendinous cords (Snell, R.S.…

This failure is due to the progressive thickening and lengthening of the leaflets that compose the mitral valve causing them to bulge (prolapse) upward into the left atrium. This prolapse can allow blood to backflow into the atrium (regurgitation). MVP is most commonly caused by abnormally stretchy valve leaflets and will affect approximately 2% of the general population. Individuals with MVP are often asymptomatic but can sometimes face life-threatening…

MITRAL STENOSIS Mitral stenosis is the narrowing of inlet valve into the left ventricle leading to an obstruction of inflow of blood from left atrium to the left ventricle during diastole. HEMODYNAMICS: Fibrosis of mitral ring, commissural adhesions and contracture of valve leaflets result in mitral stenosis. Due to the obstruction caused by the mitral stenosis left atrial pressure increases, which results in hypertrophy of left atrium. Increased left atrial pressurein turn increases pulmonary…

the left atrium and left ventricle are not working properly due to mitral valve not working appropriately. The reason this set of valves was chosen is because in the passage, it stated that the X-Ray show an enlargement in the left atrium and left ventricle. This happen is due to inefficient cycle of blood resulting in abnormal heart sound or heart murmur. Mitral valve of the left side is misshape and less flexible. Mitral valve has a leakage and allows blood to backflow into the atrium when…

has a history of mitral valve prolapse with regurgitation and high blood pressure. Mitral valve prolapse with regurgitation is a condition where the mitral valve doesn’t close properly, leading to regurgitation where the blood leaks backwards when the heart beats. The blood is then unable to reach the rest of the body, pushing the heart to pump harder in order for the blood to go to the body. Kathryn’s hypertension is a risk factor that has lead to her condition of mitral valve regurgitation.…

What conditions contribute to turbulent blood flow or heart murmurs. Turbulent blood flow occurs as blood moves through narrowed or leaking valves producing a swooshing sound over the precordium and a high heart rate combine with narrowing, causing the heart to handle a larger amount of blood flow than normal; the basis is increased blood velocity, structural valve malfunction, or atypical chambers. Some pathological causes of heart murmurs are anemia, high blood pressure, overactive thyroid,…

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…

increased blood velocity, structural valve defects, valve malfunctions, and abnormal chamber openings (Weber & Kelley, 2014). The heart has four chambers two atria, which are the upper chambers of the heart and two ventricles, which are the lower chambers of the heart. They are then further divided into left and right. Between the upper and lower chambers there are valves to prevent backflow of blood. Between the right atrium and right ventricle tricuspid valve and between…
