Mitral valve disease Common source disease Heart biology essay
The adult heart valves consist of stratified extracellular matrix ECM layers, and valvular heart disease is characterized by ECM dysregulation and mineralization. There is increasing evidence that the causes of primary mitral valve regurgitation include: Mitral valve prolapse MVP, the most common cause in developed countries. Rheumatic heart disease, the most common cause worldwide. Connective tissue diseases. A split mitral valve, a congenital heart defect, a heart problem you are born with. Endocarditis. Diuretics: These medications can reduce the workload of the heart, lower blood pressure, and remove excess water from the body. Furosemide Lasix is an example of this. Vasodilators: These are medications. Abstract. Mitral valve prolapse MVP is a common condition, with a prevalence of -3 in the general population. It is the most common cause of primary mitral regurgitation requiring surgery, making the underlying etiology of this condition of great interest. Because a familial pattern is observed in approximately half of cases, myxomatous mitral valve disease is typically recognized during a screening or routine health examination by auscultation of a heart murmur typical of mitral regurgitation. Thoracic radiography is recommended in all patients to assess the hemodynamic relevance of the valvular disease and to obtain a baseline thoracic, schematic illustration of atrial cardiomyopathy in valvular heart disease. Valvular heart disease, such as primary organic mitral valve MV regurgitation due to leaflet prolapse white arrow, leads to atrial volume and/or pressure overload and consequent increased atrial wall tension green arrows, resulting in cardiomyocytes. Mitral stenosis causes decreased blood flow through the narrowed valve opening from the left atrium to the left ventricle. As a result, the volume of blood carrying oxygen from the lungs is reduced. This can make you feel tired and short of breath. The volume and pressure of blood remaining in the left atrium increases, causing the,
