  • Descrição: The unimpeded, forward flow of blood across the mitral orifice is contingent upon a coordinated interaction between the mitral annulus, the mitral valve leaflets, the chordae tendineae, and the papillary muscles. An understanding of the functional anatomy and physiology of each of these components of the “mitral complex” is clinically important for derangement of any part may produce obstruction to blood flow or allow mitral regurgitation. The differential diagnosis then of mitral stenosis and mitral regurgitation can be functionally analyzed in terms of diseases of the mitral annulus, diseases of the mitral valve leaflets, diseases of the chordae tendineae, and diseases of the papillary muscles. By this consideration of selective involvement of the mitral complex, certain physical signs, such as the late systolic murmur that may occur in papillary muscle dysfunction, the “murmur on top of the head” heard with a ruptured chordae tendineae to the anteromedial mitral leaflet, the chordal snap of a redundant chordae tendineae, or the atrial gallop of an acutely ruptured chordae tendineae, can be sought for in an attempt to differentiate clinically the possible etiology of the disease and its anatomic area of involvement. This correlation of physical signs with the functional anatomy helps to provide an additional scientific basis to the physical examination.
