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 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...
متن کاملCaseous calcification of the mitral annulus.
A 61-year-old asymptomatic woman was referred for echocardiography to evaluate recently detected systolic murmur. Transthoracic echocardiography revealed an echodense obstructive mass in the left ventricular outflow tract of unclear origin. Subsequent transesophageal echo suggested an intracardiac calcified tumor and recommended surgical excision. Contrast-enhanced cardiac computed tomography (...
متن کاملCaseous calcification of the mitral annulus: case report
We present a rare case of probable caseous calcification of the mitral. This pathology is more frequently detected in asymptomatic women older than 70 years. To recognize this image is important because echocardiography is the easiest way to elucidate this diagnosis, and more importantly because this structure could be easily misdiagnosed as tumors, thrombus and vegetations, which are much more...
متن کاملRisk of stroke in patients with mitral annulus calcification.
63 patients with mitral annulus calcification (MAC) were followed for an average of 3.4 years. Two patients experienced TIA, both ipsilateral to a previous endarterectomy site, and IV-DSA demonstrated normal extracranial vessels. There were 3 strokes (5%), all fatal, but none could be attributed to embolism. Embolic stroke due to MAC is rare and difficult to prove due to coexistent atherosclero...
