Calcificazione caseosa dell’anulus mitralico: caso clinico e revisione della letteratura

Le résumé fourni par la source

Caseous calcification of the mitral annulus is an uncommon variant of mitral annular calcification. It appears as a round echodense mass containing central areas of echolucencies resembling liquefaction and with no flow in the central zone on color Doppler. In most cases it involves the posterior mitral annulus region, particularly in female subjects. The pathogenesis remains unclear: hypercholesterolemia and the dissolution of lipid-rich macrophages may be implicated in liquefaction necrosis. Transthoracic and transesophageal echocardiography represents the most reliable technique for diagnosis, whereas cardiac magnetic resonance imaging is the choice in doubtful cases. We report the case of an 82-year-old female patient describing different aspects of this particular clinical condition.
