Mitral annulus calcification

Mitral annulus calcification is a senile degeneration, in the mitral muscle fiber ring with calcinosis. In serious cases, can lead to mitral regurgitation appeared incomplete. Cause -- pathogenesis is not yet clear, there was mostly seen in atherosclerosis patients, most often in the posterior lobe of the ventricular surface. Europe and the United States elderly population 0.5~10.0% about the incidence of domestic no precise information, With echocardiography examination of universality, has often found. [Clinical manifestations -- decided to bad valve calcification level. Mild were no clinical manifestations : severe valve disease thickening and fixed, not blossoms ventricular systolic and smaller, mitral activity limitation, Mitral regurgitation can lead to narrow or, in the apical region and the left edge of the lower sternum can be heard systolic heart murmur to the bottom of conduction. The disease often sinus and conduction system degeneration exist, and there sinus bradycardia, atrioventricular block, Room slow rate of atrial fibrillation, a small number of patients due to valve calcium-forming peg occurred in different parts of embolization, The more common of brain and retinal artery embolization. [Diagnosis -- rely mainly on X-ray and echocardiography examination, X-ray can be found Mitral annulus calcification video. Two-dimensional echocardiography can be seen in front of atrioventricular junction is a strong reflection of the Echo group. And the posterior wall to the same campaign. [Treatment] generally no obvious hemodynamic effects, but the treatment is symptomatic heart failure symptoms treatment.
