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…

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 Prolapse is a very common heart condition; with one in four people having it with a lot of them not even knowing they have it. Mitral Valve Prolapse is the improper closure of the valve in the heart between the upper and lower chambers. The mitral valve in the heart consists of two flaps and when they do not close properly, it causes the prolapse. It can cause extra blood to leak into the heart. Mitral Valve Prolapse consists of two forms, classic and non-classic. Classic is when…

The mitral valve is a valve that allows blood flow from one chamber of the heart, the left atrium, to another called the left ventricle. In mitral valve prolapse, the valve slips backward due to the abnormal size of or damage to the mitral valve tissues. Mitral valve prolapse is a common cause of a heart murmur caused by a "leaky" heart valve. For most people with mitral valve prolapse, the cause is unknown. It can be caused by conditions in which cartilage is abnormal (connective tissue…

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…

The mitral valve (MV) plays a crucial role in cardiac function, controlling blood flow between the left atrium and left ventricle. The components of the valve include an anterior leaflet, a posterior leaflet, tendinous chords, papillary muscles, and a saddle shaped annulus at the atrioventricular junction.[1] Deviation in the morphology of any of these components of the valve may result in comprised mechanical integrity of the valve and abnormal leaflet closure.[1] With studies suggesting that…

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…

Due to the size of the breed being modified to become a short nosed dog with a very rounded skull similar to the popular pug; there are some common health problems that King Charles spaniels suffer from which include: * Mitral valve disease which is a condition that causes degeneration of the mitral heart valve that can be fatal for most dogs. All cavaliers should be screened for heart murmurs once a year beginning at age 1 year due to the commonness of the disease in the breed as it is the…

The Electrocuted Man One stormy night, as I was out walking just outside of Lime Spring, Iowa, lightning began flashing every second across the sky. The wind developed a creepy whistle to it. Whoooo! Whooo! While I walked across the bridge over the Upper Iowa River, the water started to rise. Higher and higher every second. Soon the water was over the bridge. I started to run full sprint, so I wouldn’t get caught in the rushing water. As I was running, I came to a halt. The rain was still…

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,…
