Rheumatic mitral stenosis Mitral stenosis is a form of valvular heart disease characterized by the narrowing of the mitral valve orifice. The most common cause of mitral stenosis is rheumatic fever. Mitral stenosis causes obstruction to blood flow from the left atrium to left ventricle. As a result, there is an increase in pressures in the left atrium, pulmonary vasculature, and right side of the heart, while the left ventricle is unaffected in isolated mitral stenosis. The most common cause of mitral stenosis is rheumatic heart disease with mitral commissural fusion; thickened mitral valve leaflets and thickening, shortening, fusion, and calcification of the chordae tendineae. Patients with mitral stenosis prompts a series of hemodynamic changes that frequently cause deterioration of the patient's clinical status. https://t.me/joinchat/AAAAAEIMp_P_-52SlidzHg
