  • Essay On Mitral Valve

    The mitral valve is the valve that regulates flow from the left atrium of the heart into the left ventricle. This valve is subject to a few different diseases and pathologies that affect its form and function. One of those diseases is mitral valve stenosis which is when the mitral opening between the left atrium and the left ventricle narrows and restricts the blood flow through it. The etiology, pathology and symptoms of mitral valve stenosis are well known and well documented which allows physicians to diagnose the disease with accurately with the right tools. The prognosis of the disease includes death if left untreated, but improves every year with improvements in the treatment of the disease. The most common cause of the stenosis is an infection caused by rheumatic fever which causes the leaflets of the mitral valve to get thicker or to fuse together. Mitral valve stenosis can also be caused by a buildup of calcium deposits on the leaflets, or by a congenital defect where the leaflets are not correctly formed. When a patient has mitral valve stenosis, the patient 's left atrial size and pressure increase to overcome the smaller passageway to the left ventricle. This means that the heart, mainly the left atrium has to work harder to keep a normal cardiac output. If left untreated, the pressure in the…

  • Mitral Valve Prolapse Effect

    Different Effect of Mitral Valve Prolapse History of the Disease One of the most common cardiac abnormalities in the United States is Mitral Valve Prolapse, also known as MVP, which affects about 2-6% of Americans. It is a disorder of the bicuspid valve, which causes backflow of blood from the left ventricle back into the left atrium (Sims & Miracle, 2007). MVP can also be identified as click-murmur syndrome, floppy mitral valve, and Barlow syndrome (Kornusky & Cabrera, 2014). In past studies,…

  • Mitral Valve Regurgitation Essay

    Introduction Mitral valve regurgitation, also called mitral regurgitation, is a condition in which blood leaks from the mitral valve in the heart. The mitral valve is located between the upper left chamber of the heart (left atrium) and the lower left chamber of the heart (left ventricle). Normally, this valve opens when the atrium pumps blood into the ventricle, and it closes when the ventricle pumps blood out to the body. Mitral valve regurgitation happens when the mitral valve does not close…

  • Essay On Mittral Valve Prolapse

    not at fault. Mitral valve prolapse is a condition that the cause is still unknown. Scientists believe it may be hereditary and people can be born with it, but never experience any symptoms. Even though mitral valve prolapse is not usually life-threatening, however some people may require treatment and a complete change of lifestyle. Mitral valve prolapse, or MVP, is defined as a valvular heart disorder. Where one or both mitral…

  • Temperature And Temperature Experiment

    labquest and set up for new data collection. Rubber stopper assembly obtained and connected to plastic tubing and valves. Connector attached at free end of tubing to the gas pressure sensor with a clockwise turn. Two-way valve left open. Rubber-stopper assembly inserted tightly into the 125 mL Erlenmeyer flask. Closed the two way valve so it was perpendicular with valve stem. Mode changed to selected events on labquest. Graph settings changed to display pressure vs. temperature graph,…

  • Faucet Repair Case Study

    Before calling a plumber in Arlington, check the water pressure at other faucets. If the water pressure is low only at a single faucet, first ensure the shut off valve is open. Next, inspect the aerator for clogging due to hard water sediment. Soaking in vinegar and scrubbing with a soft brush should correct the problem. Otherwise, replace the aerator. While the aerator is off check the water pressure at the faucet. If low, a problem is affecting the faucet. Faucets receive significant use,…

  • Bjork-Shiley Heart Valve Case Study

    Every year, thousands people get heart valve replacements. There are multiple options for replacement valves that can be generalized as either mechanical or biological. One of the mechanical options from the 1970s and 1980s was the Bjork-Shiley valve, which became infamous because of the controversy surrounding its stress fracture failures. These failures resulted the death of about 400 people, causing the valve to be taken off the market. The decisions made leading to this issue must be…

  • Heat Transfer Lab Report

    Next, the arrow icon was clicked to begin measuring temperatures. After that, the water drain valve was closed tightly. Next, the water flow was set to 2 gpm, and the steam valves were opened. Flow rate oscillated up and down during the process of heating, so adjustment was required to maintain the desired flow rate. Then, temperatures were recorded if stabilization and no significant changes occurred. Next, the tubes were examined, and the transition between boiling and non-boiling heat…

  • French Horn Evolution

    still highly limited in reaching its full musical potential. 1.3 Addition of valves The addition of valves around 1815 is arguably the most significant development in French horn technology. A crude piston valve system, known as the Stölzel valve, was developed around 1815 by Heinrich Stölzel and Friedrich Blühmel. In this system created by Stölzel and Blühmel, air entered through the bottom of the final valve in the sequence. The air would then travel either through an extended length of…
