[The echocardiogram in mitral anulus calcification]
Insights
Echocardiography reveals mitral annular calcifications in elderly patients, often causing murmurs. This imaging technique accurately detects and quantifies calcifications, distinguishing them from other cardiac conditions.
Area of Science:
- Cardiology
- Medical Imaging
Context:
- Mitral annular calcification (MAC) is common in elderly patients.
- Intracardiac calcifications are often undetected by chest X-ray.
- Abnormal heart murmurs can stem from calcifications.
Purpose:
- To investigate the prevalence and impact of mitral annular calcifications.
- To evaluate echocardiography's role in detecting and characterizing cardiac calcifications.
- To differentiate degenerative aortic cusp calcifications from other cardiac pathologies.
Summary:
- Echocardiography identified mitral annular calcifications in 61 patients, causing abnormal heart murmurs.
- Chest X-rays only identified calcifications in 6 patients, highlighting echocardiography's superior detection.
- Aortic cusp calcifications, present in 75% of patients, can mimic other conditions like valvular disease or cardiomyopathy.
Impact:
- Echocardiography is crucial for diagnosing mitral annular calcifications and their associated murmurs.
- Accurate differentiation of calcifications prevents misdiagnosis of conditions like valvular heart disease.
- Continuous sector scan echocardiography aids in distinguishing degenerative calcifications from other cardiac abnormalities.
Abstract:
In agreement with the known high incidence of mitral anulus calcification in elderly patients, the authors have found corresponding calcifications in echocardiographic examinations in 61 patients as the single or additional cause of an abnormal systolic or diastolic murmur. The intracardiac calcifications were known of from the chest X-ray only in 6 patients. The echocardiograms served to locate and estimate the amount of the calcification. Calcifications of the aortic cusps, found in 75% of patients, may be of degenerative origin. The echocardiographic presentation of the degenerative calcifications can be misinterpreted either as postrheumatic valvular disease, posterior pericardial effusion or hypertrophic cardiomyopathy. Registration by continuous sector scan was necessary to differentiate these entities.
