Why the study?

Does MDCT detection of mitral valve calcification correlate with echocardiographic severity of mitral valve disease in patients undergoing both chest CT and echocardiography?

Population

390 patients who underwent MDCT of the chest and echocardiography.

Comparison

MDCT of the chest with visual grading of mitral… vs Echocardiography

Design

Cross-sectional

Overview

Incidental MDCT mitral calcification may warrant echocardiography; supports correlation with sclerosis severity but leaves open prospective validation.

Structured PICO

Does MDCT detection of mitral valve calcification correlate with echocardiographic severity of mitral valve disease in patients undergoing both chest CT and echocardiography?

P
Population
390 patients (227 men and 163 women; mean age, 62.4 +/- 12.2 years) who underwent MDCT of the chest and echocardiography.
I
Intervention
MDCT of the chest with visual grading of mitral valve leaflet and annulus calcification (scale 0-3)
C
Comparator
Echocardiography (hemodynamic data and severity of mitral valve disease)
O
Outcome
Agreement between MDCT mitral valve calcification and echocardiographically proven mitral valve sclerosis/stenosissurrogate

Mitral valve leaflet calcification incidentally detected on chest MDCT strongly correlates with echocardiographically proven mitral valve sclerosis or stenosis, suggesting these patients may benefit from functional echocardiographic assessment.
