Left atrial enlargement can be mild, moderate or severe depending on the extent of the underlying condition. Although other factors may contribute, left atrium size has been found to be a predictor of mortality due to both cardiovascular issues as well as all-cause mortality.
Over 90% of stroke-causing clots that originate in the heart in patients with non-valvular AF are formed in the left atrial appendage. [2] [3] LAAO does not completely eliminate the risk of stroke in patients with AF but it does reduce the risk of stroke from emboli that originate in the left atrial appendage. [4] The left atrial appendage can ...

These clots develop in a small pouch called the left atrial appendage (LAA). If a clot dislodges and travels to the brain, it can cause a stroke.
The left atrial appendage can serve as an approach for mitral valve surgery. [16] The body of the left atrial appendage is anterior to the left atrium and parallel to the left pulmonary veins. The left pulmonary artery passes posterosuperiorly and is separated from the atrial appendage by the transverse sinus. [17]
A common example that demonstrates this is the visibility of the left atrial appendage. This structure is known to form clots in atrial fibrillation and the LAA is rarely seen on TTE but readily seen on TEE. Cardioversion of atrial fibrillation in someone not on anticoagulation would require TEE to best visualize the LAA to rule out a thrombus.
These normal ranges are not as well defined for TEE and so there is less accepted standards (e.g., left atrial enlargement). [ citation needed ] Some risks are associated with the procedure, such as esophageal perforation [ 6 ] around 1 in 10,000, [ 7 ] and adverse reactions to the medication.
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.
