Mitral Annulus Calcification.
Mitral annulus calcification (MAC) is a chronic, degenerative process in the fibrous base of the mitral valve. Although MAC was initially thought to be an age-related degenerative process, there is accumulating evidence that other mechanisms, such as atherosclerosis and abnormal calcium-phosphorus metabolism, also contribute to the development of MAC. Despite its frequency, the clinical relevan...
متن کاملCaseous Necrosis of Mitral Annulus
Masses or mass-like lesions located in proximity to mitral valve encompass a wide range of differential diagnoses including neoplasias, abscesses, thrombi, and rarely caseous calcification of mitral annulus. Due to asymptomatic presentation, its diagnosis is usually incidental. Echocardiography is the first choice of imaging in evaluation. Cardiac computed tomography (CT) is helpful in establis...
متن کامل[Mitral valve replacement for a severely calcified mitral annulus].
An 80-year-old woman was referred to our institution because of acute heart failure due to moderate mitral stenosis and severe regurgitation. After medical treatment of heart failure, she underwent mitral valve surgery. Intraoperatively severe calcification of the posterior mitral annulus was revealed. We excised only the anterior mitral leaflet and preserved the posterior mitral leaflet to pre...
متن کاملMorphofunctional Abnormalities of Mitral Annulus and Arrhythmic Mitral Valve Prolapse
BACKGROUND Arrhythmic mitral valve prolapse (MVP) is characterized by myxomatous leaflets and left ventricular (LV) fibrosis of papillary muscles and inferobasal wall. We searched for morphofunctional abnormalities of the mitral valve that could explain a regional mechanical myocardial stretch. METHODS AND RESULTS Thirty-six (27 female patients; median age: 44 years) arrhythmic MVP patients w...
متن کاملAnnulus fibrosus calcification of the mitral valve.
C ALCIUM deposition in diseased heart valves may be demonstrated frequently in necropsy studies, but these deposits are usually overlooked clinicaIIy unless the heart is carefuIly examined roentgenographically. Sosman1 discusses in detail a simple method of demonstrating the presence of calcific deposits within the heart by x-ray. He suggests a small fluoroscopic aperture and a screen of high i...
