- W4377019907 abstract "Abstract The caseous calcification of the mitral annulus (CCMA) is a rare degenerative condition of the mitral valve (0.067% prevalence in the general population) that generally affects older women with hypertension, chronic kidney disease and dyslipidemia. Usually CCMA is asymptomatic and it is associated with mild to moderate mitral regurgitation and it can cause severe mitral valve dysfunction that requires surgical treatment. CASE 1: A 84–year–old woman, with arterial hypertension, was evaluated in our clinic to perform a transthoracic echocardiogram (TTE) for a previous finding of heart murmur. TTE reveled at the level of the posterior mitral annulus a hyperechoic roundish formation with a central eco–shiny area with a maximum diameter of 20x20 mm. A tridimensional trans–esophageal echocardiography (3D TEE) allowed a better characterization of the mass showing well–defined contours, adhered to the posterior mitral annulus, systolic dislocation of the anterior mitral leaflet, with slight mitral regurgitation. Considering the morphological characteristics of the mass we concluded for a presumptive diagnosis of CMAC. We recommended regular follow–up to the patient. After 6 and 12 months the mass did not change in size and echostructure. CASE 2: An 88–year–old woman with chronic kidney disease, high blood pressure and chronic ischemic heart disease was admitted to our ward for acute heart failure. TTE showed a large an echodense mass (43 × 19 mm) involving the posterior mitral annulus, with a central echo–lucent area. A 3D TEE was performed with better mass characterization: involvement of the entire posterior mitral ring, reduced movement of the posterior mitral flap, anterior mitral flap with normal morphology and normal mobility. In consideration of the echocardiographic characteristics we concluded for the presence of CMAC. We discharged the patient with indication for a regular clinical and echocardiographic follow–up. Conclusions The 3D TTE provides adequate morphostructural information that allows in most cases to characterize the CCAM. When the transthoracic approach is difficult due to poor acoustic windows, 3D TEE can be used. Only in rare cases it is necessary to use second–level diagnostic tests such as CT and Cardiac Magnetic Resonance Imaging." @default.
