Mitral annular. Medical search. Frequent questions

Mitral annular calcification (MAC) is a multifactorial chronic degenerative process in which calcium with lipid is deposited (calcified) in the annular fibrosa ring of the heart's mitral valve. (wikipedia.org)
However, mitral annular calcification remains clinically significant because while in many cases the calcification is limited to the annulus and proximal leaflet bases, it may also extend further into the valve structure. (wikipedia.org)
If mitral regurgitation is suspected clinically, transesophageal echocardiogram (TEE) may be needed, as the shadowing of the left atrium seen in a transthoracic echocardiogram often impairs the assessment of the degree of calcification present. (wikipedia.org)
Interestingly, the two annuli of the mitral valve are not affected equally, with the posterior annulus demonstrating calcification more frequently than the anterior annulus. (wikipedia.org)
