Normal Values for Left Ventricular Volume in Infants and Young Children by the Echocardiographic Subxiphoid Five-Sixth Area by Length (Bullet) Method

The normal range for LVEDV by the subxiphoid echocardiographic bullet method is reported for newborns, infants, and young children. LVEDV should be indexed to BSA1.38, which is consistent with the known relationship between LV size and body size. In children aged ≤3 years, these data can be used to calculate Z scores for LVEDV by the subxiphoid bullet technique independent of age or gender.
