Valvular Heart Disease
2010, Brocklehurst's Textbook of Geriatric Medicine and GerontologyAssessment of atrial conduction time by tissue Doppler echocardiography and P-wave dispersion in patients with mitral annulus calcification
2010, Journal of ElectrocardiologyCitation Excerpt :It is known that mitral annulus calcification (MAC) is a chronic, noninflammatory, degenerative process of the fibrous support structure of the mitral valve.1,2 Previous studies have put forward that patients with MAC have a higher incidence of left atrial (LA) enlargement.3 Furthermore, MAC was proven to be associated with several conduction disorders, such as sinoatrial disease, atrial fibrillation (AF), atrioventricular block, left anterior hemiblock, and interventricular conduction defects, but the true incidence and the exact underlying mechanisms of AF were uncertain.4,5
Heart Disease and Aging
2006, Medical Clinics of North AmericaCitation Excerpt :In a prospective study of 1881 older women and 924 older men, mean age 81 years, the prevalence of MAC was higher in women (52%) than in men (36%) (see Table 3) [31]. Persons who have MAC have a higher prevalence of atrial fibrillation [45,46], new coronary events [47,48], CHF [47], bacterial endocarditis [48], permanent pacemaker implantation [47], thromboembolic stroke [46–51], and transient cerebral ischemic attack [51] than do persons who do not have MAC. Hypertrophic cardiomyopathy is a primary myocardial disorder with a hypertrophied and nondilated left ventricle that is not caused by other cardiovascular disease.
Clinical significance of calcification of the fibrous skeleton of the heart and aortosclerosis in community dwelling elderly. The Cardiovascular Health Study (CHS)
2006, American Heart JournalCitation Excerpt :However, the strength of association between these 3 forms of ectopic valvular calcification with CVD varied, MAC having the strongest relationship with CVD. The high prevalence of calcified mitral annulus and AVS, and their relationship to age in the present study are consistent with prior clinical studies and studies done at autopsy.2,5,6,9,11-20 The present study extends those findings by noting similar relationships of AAC to aging and disease.
