Mitral valve stenosis class III or IV symptoms. Once an individual develops NYHA class III or IV symptoms, the progression of the disease accelerates and the patient's condition deteriorates. Upon auscultation of an individual with mitral stenosis, the first heart sound is usually loud and may be palpable (tapping apex beat) because of increased force in closing the mitral valve. The first heart sound is made by the mitral and tricuspid heart valves closing. These are normally synchronous, and the sounds are termed M1 and T1, respectively. M1 becomes louder in mitral stenosis. It may be the most prominent sign. If pulmonary hypertension
Mitral valve prolapse with palpitations, atypical chest pain, dyspnea on exertion, low body mass index, and electrocardiogram abnormalities in the setting of anxiety, syncope, low blood pressure, Migraine-Like Headache, orthostatic hypotension, lightheadedness, and other signs suggestive of autonomic nervous system dysfunction (dysautonomia). Mitral valve prolapse is frequently associated with mild mitral regurgitation, where blood aberrantly flows from the left ventricle into the left atrium during systole. In the United States, MVP is the most common cause of severe, non-ischemic mitral regurgitation. This is occasionally due to rupture of the chordae tendineae that support the mitral valve. MVP may occur with greater frequency in
