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 …show more content…
This will eventually cause the heart to fail and death of the patient to occur. However, there are many treatment options for someone with mitral valve stenosis including medications if it is not severe. If it is severe, treatments can range from balloon mitral valvuloplasty and surgical commissurotomy to mitral valve replacement. As research and development into the procedures and replacement valves improve in the future, the prognosis of this disease will also

Furthermore, if clumping occurs this may lead to heart attack, stroke or even death, due to stoppage of blood flow. The result of blood clumping originates from incompatible ABO and Rh blood groups between the donor blood and the recipient blood. In other words, if the recipient has antibodies against the donors blood this may result in clumping.…

    Some have more rhythm problems than others; some will have more valve issues than others. The most significant long term consequence is heart failure. The goal of surgical repair and treatment is to preserve the cardiac muscle and meet the oxygen demands of the body. The most significant consequence of TOF is heart rhythm problem’s and damage to the cardiac muscle. In 2% of all repaired TOF patient’s sudden cardiac death has been reported (Doyle, Kavanaugh-Mchugh, & Graham, 2011).…

    That can affect not only the patient but others around them. The lung could be punctured; in most cases, it is small and resolves by itself.

    Rubs are abnormal noises by the rubbing of the pericardium and the fibrous sac surrounding the heart due to an inflammation or enlargement of the heart. Diagnostic testing will be needed to confirm their findings of abnormalities present in the heart. Much like an electrocardiogram, chest x-ray, and most likely an echocardiogram. An electrocardiogram, or EKG/ECG, will assess heart rate, and rhythm, while the chest x-ray looks at the size of the heart and affirms the presence of fluid. The most recommended test in diagnosing CHF would be an echocardiography that assess the anatomy and function of the heart.…

    There are automated and manual BP machines used to measure BP. Most automated machines use the oscillometric technique, this relies on the detection of variations in pressure oscillations due to arterial wall movement below the cuff. Manual machines use an auscultatory method, the upper arm cuff in inflated to occlude the brachial artery and then involves listening to the Korotkoff sounds through a stethoscope while the cuff is slowly deflated (Denver 2013). There is increasing evidence that automated machines may not achieve acceptable levels of accuracy in certain conditions such as, arrhythmias and vascular disease (Wedgbury et al 2008). A study by Coe and Houghton (2002) found that “6.5% of daycase patients would have been inappropriately diagnosed as hypertensive when their blood pressure was taken using an automated blood pressure…
