title: Liquefaction necrosis of mitral annulus calcification in a patient with chronic renal failure: an unrecognized diagnosis.
abstract: Mitral annulus calcification is one of the most common cardiac calcifications. In patients with end-stage renal disease undergoing echocardiography, it can be detected in more than 40%. A specific form of mitral annulus calcification is liquefaction necrosis. It is often not adequately recognized by echocardiographers or clinicians and can be mistaken for cardiac tumor or infective vegetation. Here we report a case of liquefaction necrosis of mitral annulus calcification, mimicking an infective vegetation of the mitral valve apparatus in a patient with chronic renal failure.
