Why the study?
Is mitral annulus calcification associated with other cardiac structural abnormalities on echocardiography?
Population
24,380 echocardiograms performed for clinical reasons between the years 1984 and 1998
Comparison
Presence of Mitral Annulus Calcification (MAC) vs Absence of Mitral Annulus Calcification
Design
Cross-sectional

MAC may flag coexisting valvular and myocardial abnormalities on echo; hypothesis-generating for prognostic studies.
Is mitral annulus calcification associated with other cardiac structural abnormalities on echocardiography?
Mitral annulus calcification is independently associated with significant structural heart abnormalities, suggesting it may serve as a marker for other cardiac disorders.
Movahed et al. (2007) studied this question.
