Correlation between cardiac catheterization and echocardiography in assessing the severity of mitral stenosis
Insights
Cross-sectional echocardiography accurately assesses mitral valve area in mitral stenosis patients. This method is a reliable alternative to cardiac catheterization for evaluating stenosis severity.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Mitral stenosis diagnosis requires accurate assessment of mitral valve area and stenosis severity.
- Cardiac catheterization is an invasive standard for evaluating mitral valve area.
- Non-invasive imaging modalities are sought for reliable mitral stenosis assessment.
Purpose of the Study:
- To compare the accuracy of M-mode and cross-sectional echocardiography with cardiac catheterization in measuring mitral valve area.
- To determine the reliability of cross-sectional echocardiography for assessing mitral stenosis severity.
Main Methods:
- 162 consecutive patients with mitral stenosis underwent M-mode and cross-sectional echocardiography.
- Mitral valve area was measured using both echocardiographic methods.
- Cardiac catheterization was performed in 69 patients, with mitral valve area calculated in 53.
- Correlation analysis was performed between echocardiography and catheterization results.
Main Results:
- Cross-sectional echocardiography showed a high correlation (r=0.92) with cardiac catheterization for mitral valve area measurement.
- M-mode echocardiography demonstrated a weaker correlation (r=0.38) with cardiac catheterization.
- Cross-sectional echocardiography proved to be a reliable method for assessing mitral stenosis.
Conclusions:
- Cross-sectional echocardiography is a highly reliable, non-invasive method for measuring mitral valve area in mitral stenosis.
- This technique offers a dependable alternative to invasive cardiac catheterization for evaluating stenosis severity.
Abstract:
During a 12-mth period 162 consecutive patients with mitral stenosis underwent examination by M-mode as well as cross-sectional echocardiography. The mitral valve area was measured by cross-sectional echocardiography ad the severity of mitral stenosis by M-mode echocardiography. Out of the total, 69 patients underwent left and right heart catheterization and in 53 of these the mitral valve area was calculated. A correlation of r=0.92 for the mitral valve area was found between sector scan echocardiography and cardiac catheterization, whereas the correlation between M-mode echocardiography and catheterization yielded a result of only r=0.38. Thus the assessment of the severity of mitral stenosis by cross-sectional echocardiography is a reliable alternative to cardiac catheterization.
