Common Femoral Vein-to-Artery Diameter Ratio for Detection of Elevated Left Ventricular End-Diastolic Pressure: Diagnostic Accuracy Study
Sponsor: Burapha University
Summary
This prospective cross-sectional diagnostic accuracy study enrolled patients undergoing coronary angiography and left heart catheterization at Burapha University Hospital, Thailand. The diameters of the common femoral vein and common femoral artery were measured using ultrasonography, and the common FVD/FAD ratio was calculated. LVEDP, measured during left heart catheterization, served as the reference standard. An elevated LVEDP (\>16 mmHg) was defined as volume overload. Diagnostic performance was evaluated using receiver operating characteristic (ROC) curve analysis.

Ultrasound Measurement of Common Femoral Vein-to-Artery Diameter Ratio
Ultrasound measurement of the common femoral vein and common femoral artery diameters performed in the supine position. The common femoral vein-to-artery diameter ratio is calculated from the measured vessel diameters and evaluated as a diagnostic index for detecting elevated left ventricular end-diastolic pressure. The ultrasound examination is non-invasive and does not involve administration of any therapeutic intervention.
