ARDMS AE-Adult-Echocardiography - AE Adult Echocardiography Examination

Comprehensive and Detailed Explanation From Exact Extract:

The left atrial volume index (LAVI) is the left atrial volume normalized to the patient's body surface area (BSA), which accounts for patient size. To calculate BSA, height and weight are required, most commonly using formulas such as the Mosteller formula.

Therefore, height is a necessary parameter to calculate the left atrial volume index. Age, blood pressure, and cardiac output are not used in the calculation of LAVI but may be clinically relevant for interpretation.

This approach standardizes LA size across patients of different body habitus, making LAVI a more accurate and reproducible measure of LA remodeling and a predictor of cardiovascular outcomes.

The echocardiography guidelines and textbooks emphasize the importance of indexing LA volume to BSA and highlight height as a required measurement for this purpose .
