title: [Calcification of the mitral ring and semilunar valves: clinico-instrumental aspects. Sensitivity and diagnostic specificity of M-mode echocardiography versus autopsy findings].
abstract: Mitral ring calcification is a frequent finding in geriatric patients. The aim of this study was: 1) to analyze clinical and instrumental features of patients with calcific mitral ring identified through M-mode echocardiography (group A: 96 pts) with respect to those observed in a control group (group B: 104 pts); 2) to define the sensitivity and specificity of M-mode echocardiography in the diagnosis of mitral ring and aortic valve calcification by means of comparison with autopsy findings. Data on arterial hypertension, previous myocardial infarction, heart failure, phosphoremia and calcemia values were similar in both groups. On the contrary, in group A, permanent or paroxysmal atrial fibrillation, aortic valve calcification and left atrial diameter was significantly higher then in group B (p less than 0.05; p less than 0.001; p less than 0.001 respectively). The prevalence of AV and IV cardiac blocks was similar in both groups. Twelve group A patients were restudied with M-mode echocardiography, after a variable period of time, to evaluate the velocity of calcification progression. An autopsy was carried out on the twenty-six pts who died within 3 months after the M-mode echocardiography study. The evaluation of the autoptic findings was performed with high resolution radiographic image, obtained from a heart transverse section containing mitral and aortic plane.(ABSTRACT TRUNCATED AT 250 WORDS)
