Mitral Stenosis Heart Sound
Manage episode 313651251 series 3279691
In mitral stenosis, mitral valve leaflets become thickened and immobile and the mitral orifice becomes narrowed due to fusion of the commissures and the presence of shortened, thickened and matted chordae. The most common cause is rheumatic fever, even though many patients do not recall the disorder. Symptoms of mitral stenosis correlate poorly with disease severity because the disease often progresses slowly, and patients unconsciously reduce their activity. Many patients are asymptomatic until they become pregnant or AF develops. Initial symptoms are usually those of heart failure (eg, exertional dyspnea, orthopnea, paroxysmal nocturnal dyspnea, fatigue).
