Hypothesis
Is mitral annulus calcification associated with cardiac abnormalities?
Conclusion
Mitral annulus calcification is linked to significant structural heart abnormalities.
Supporting Evidence
- MAC was reported in 1,494 (6.1%) subjects.
- Age, LVH, MR, TR, AS, LA enlargement, and reversed E/A ratio were independently associated with MAC.
- MAC was noted in 11.7% of patients with MR vs. 4.3% without MR.
- MAC was noted in 13.9% of those with TR vs. 4.5% without TR.
- MAC was noted in 10.6% with LVH vs. 4.2% without LVH.
- MAC was noted in 14.8% with AS vs. 5.5% without AS.
- MAC was noted in 9.4% with reversed E/A ratio vs. 3.8% without reversed E/A ratio.
- MAC was noted in 8.2% with LA enlargement vs. 4.8% without LA enlargement.
Takeaway
When doctors find calcium buildup in a heart valve, it might mean there are other heart problems too.
Methodology
Retrospective review of 24,380 echocardiograms from 1984 to 1998.
Potential Biases
The diagnoses of cardiac abnormalities were not standardized.
Limitations
The study relied on previous reports, leading to non-uniform assessment of echocardiographic abnormalities.
Participant Demographics
Mean age of patients with MAC was 68 years.
