La Volume Index
Left Atrial Volume Index (LAVI) Calculator - MDApp
Left Atrial Volume Index (LAVI) has been found to correlate with mortality from cardiovascular disease and may be measured at the end-ventricular systole, when the LA is at its maxim size. Gender differences are then accounted for by indexing the volume to body surface area (BSA) via the Mosteller equation.

Reference Ranges & Partition Values for LA Volume Index (mL/m
LA Volume & LA Volume Index (Biplane Area-Length Method) When left atrial (LA) size is measured clinically, LA volume determinations are preferred over linear measurements since they allow more accurate assessment of the asymmetric remodeling of the LA chamber.

Left atrial volume index in healthy subjects: clinical and ...
Left atrial (LA) size is related to cardiovascular morbidity and mortality. The relative role of multiple determinants of LA morphology in healthy subjects remains incompletely defined. The aim of this study is to define normal ranges for LA diameters and volume index (LAVi), and to investigate clinical and echocardiographic correlates.

Left atrial volume index in highly trained athletes - PubMed
The range of LA volume index was 26 to 36 mL/m(2) (mean 28.2 +/- 9.2) in men and 22 to 33 mL/m(2) (mean 26.5 +/- 7.2) in women (P < .01). LA volume index was mildly enlarged in 150 athletes (24.3%) and moderately enlarged only in 20, all males (3.2%). Mild mitral regurgitation was observed in 64 athletes (10.3%).

Left atrial volume index: a predictor of adverse outcome in patients ...
Increased LA volume index was also revealed to be an independent predictor for cardiovascular events other than death (for each 5 mL/m(2) increase, hazard ratio, 1.44; 95% confidence interval, 1.12-1.83; P < .01).

Left Atrial End-Diastolic Volume Index as a Predictor of Cardiovascular ...
the left atrial end-systolic volume index (laesvi), representing the largest left atrial (la) volume, is a known predictor of cardiovascular outcomes and is the recommended measure of la size by the american society of echocardiography. 1 the la residual volume index or the la end-diastolic volume index (laedvi) is the smallest la volume, …

Normal reference ranges for left and right atrial volume indexes and ...
Upper normal reference values were 41 mL/m 2 for maximum (max) LAVI and 19 mL/m 2 for minimum (min) LAVI. The lower normal reference value was 45% for LAEF. The respective values for RA were 47 mL/m 2 , 20 mL/m 2 , and 46%. The only relevant gender difference was a higher upper normal max RAVI among males vs. females.

Too much pressure or too much blood volume can both cause the left atrium to become bigger, which causes left atrial enlargement (LAE). The increased pressure or volume is caused by an underlying cardiovascular condition—discovering that someone has LAE should initiate the search for the condition that is causing it.
