How to Measure Left Atrial Volume

Echocardiography, 2004
Figure 1. M-mode measurement of LA size from a parasternal window. According to ASE guidelines, the measurement (leading-edge to leading-edge method) is performed at end-systole, measured at the maximum dimension from the leading edge of the posterior wall of the aorta, to the dominant line of the posterior wall of the LA (arrows). aortic root.

Left atrial volume and function in patients with atrial fibrillation

Current Opinion in Cardiology, 2014
This review of emerging approaches to left atrial imaging in atrial fibrillation is relevant because there has been considerable recent development in the noninvasive characterization of left atrial structure and function. Concurrently, the identification and treatment of atrial fibrillation and the prevention of thromboembolism are evolving.

Effects of obstructive sleep apnea treatment on left atrial volume and left atrial volume index

Sleep and Breathing, 2007
Obstructive sleep apnea (OSA) and increased left atrial volume (LAV) both independently increase cardiovascular mortality. We hypothesized that treatment of OSA with continuous positive airway pressure (CPAP) may decrease LAV. We retrospectively identified 47 OSA patients receiving CPAP who had echocardiograms done before and after polysomnography ...

Left Atrial Volume as an Index of Left Atrial Size: A Population-Based Study.

Journal of the American College of Cardiology, 2003
We studied left atrial volume (LAV) as an index of atrial size.Increased left atrial dimension (LAD) measured by M-mode echocardiography is a risk factor for atrial fibrillation, stroke, and death.A random sample of residents of Olmsted County, Minnesota, age > or =45 years (n = 2,042) underwent Doppler echocardiography with assessment of LAD and LAV ...

Correlation of Left Atrial Diameter by Echocardiography and Left Atrial Volume by Computed Tomography

Journal of Cardiovascular Electrophysiology, 2009
Introduction: For patients undergoing catheter ablation of atrial fibrillation (AF), left atrial size is a predictor of recurrence of AF during follow‐up. For this reason, major clinical trials have used a left atrial diameter (LAD) of more than 5.0 or 5.5 cm, assessed by echocardiography, as an exclusion criterion for patients

Formulaic quantification of echocardiographic left atrial volume

Journal of Electrocardiology, 2009
The association between increasing severity in abnormal atrial depolarization and left atrial (LA) volume derived by transthoracic echocardiogram (TTE) has been described through the following regression formula: LA end-systolic volume index (LAVI [milliliter]) = 8.0 + 0.2 (P-wave duration [millisecond]) (r = 0.47; P = .0002).

Left Atrial Size and Left Atrial Volume Index as Predictors of Atrial High‐Rate Episodes

Pacing and Clinical Electrophysiology
ABSTRACTBackgroundRecent studies have shown that atrial high‐rate episodes (AHREs) are associated with adverse cardiovascular outcomes, including an increased risk of stroke, cardiovascular mortality, and future atrial fibrillation. Despite efforts to identify predictors for AHRE, the relationship between left atrial morphology and AHRE remains unclear.

Left Atrial Volume: Clinical Value Revisited

Current Cardiology Reports, 2012
Left atrial (LA) volume and function are robust markers of cardiovascular risks and adverse cardiac outcomes. With advances in imaging technology, including tissue Doppler, strain, and strain rate imaging, we can now determine LA volume and function more precisely and this is anticipated to augment our ability to risk stratify, incremental to clinical ...

Left Atrial Volume Calculation by Angiocardiography in Children

Chest, 1973
Two angiographic methods for left atrial volume estimation are described. One (area-length method) utilizes an ellipsoid reference figure, as currently used for left ventricular volume studies. The appendage is excluded in the measurements but a regression formula corrects the initial calculation to arrive at a total left atrial volume estimation.

Using Traditional Measurements of the Left Atrial Diameter to Predict the Left Atrial Volume Index

Echocardiography, 2007
Background: Left atrial enlargement by echocardiography is associated with adverse cardiovascular outcomes, yet the best method for assessing left atrial size has not been established. We sought to correlate the traditional left atrial diameter (LAD) measured in the parasternal view with the recently characterized left atrial volume index (LAVI ...
