Liquefaction necrosis of calcified mitral annulus.
Echogenicity within the left atrioventricular groove can be due to many conditions, such as mitral annular calcification, abscess, dilated coronary sinus, and aneurysm of the left circumflex coronary artery. However, in a patient who has no systemic symptoms, a bright, round echodensity with central echolucency and smooth borders in the mitral annulus is characteristic of liquefaction necrosis of a calcified mitral annulus. We report the occurrence of this rare manifestation in a 60-year-old patient who presented with myocardial infarction.
