Correlation between echocardiography and cardiac catheterization in assessing the severity of aortic stenosis

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Aortic stenosis (AS) is a common valvular heart disease.
• Accurate assessment of AS severity is crucial for patient management.

Purpose of the Study:

• To evaluate the correlation between cross-sectional echocardiography and cardiac catheterization in assessing aortic stenosis severity.
• To determine the diagnostic utility of aortic valve separation measurements by echocardiography.

Main Methods:

• Echocardiography was performed on 81 adult patients with aortic stenosis.
• Cardiac catheterization was used as a reference standard in 40 patients.
• Aortic valve separation was measured using cross-sectional echocardiography.

Main Results:

• A good correlation was observed between echocardiography and cardiac catheterization findings.
• Aortic valve separation ≤7 mm indicated severe AS.
• Aortic valve separation ≥12 mm ruled out significant AS.
• A separation of 8-11 mm represented an intermediate range.

Conclusions:

• Cross-sectional echocardiography is a reliable method for the initial evaluation of aortic stenosis severity.
• Aortic valve separation measurements provide valuable information for stratifying AS severity.
