LAE has been found to be correlated to body size, independent of obesity, meaning that LAE is more common in people with a naturally large body size. [1] Also, a study found that LAE can occur as a consequence of atrial fibrillation (AF), [ 3 ] although another study found that AF by itself does not cause LAE.
The left atrial volume is commonly measured by echocardiography or magnetic resonance tomography.It is calculated from biplane recordings with the equation: = where A4c and A2c denote LA areas in 4- and 2-chamber views respectively, and L corresponds to the shortest long-axis length measured in either views.

High in the upper part of the left atrium is a muscular ear-shaped pouch – the left atrial appendage (LAA) (lat: auricula atrii sinistra), which has a tubular trabeculated structure. [9] LAA anatomy as seen in a CT scan is characterized as being in one of four groups: chicken wing (48%), cactus (30%), windsock (19%), and cauliflower(3%).
The left atrial appendage is a pouch-like structure located in the upper part of the left atrium. [1] Left atrial appendage occlusion (LAAO) is an alternative therapy to oral anticoagulation in a certain subset of patients with atrial fibrillation. Atrial fibrillation is characterized by an irregular and uncoordinated pumping function of the atria.
Atrial enlargement refers to a condition where the left atrium or right atrium of the heart is larger than would be expected. It can also affect both atria. It can also affect both atria. [ 1 ]

The esophageal electrogram recording feature of the ICS3000 offers a filtered Butterworth high-pass esophageal left atrial electrogram. In combination with the surface ECG, filtered bipolar esophageal left atrial electrogram (LAE) recording can be of advantage in all situations requiring doubtless recognition of the atrial activities.
