Left Atrial Morphology and Function
In the prediction of the risk of cardiovascular events, the role of the left ventricle (LV) has been established for a long time, in the general population and especially in patients with heart failure. LV dimensions and systolic function, the latter mainly expressed as ejection fraction, were the first variables investigated; over the years, the role of predictors of cardiovascular outcomes ha...
متن کاملLeft atrial relaxation and left ventricular systolic function determine left atrial reservoir function.
BACKGROUND Determinants of left atrial (LA) reservoir function and its influence on left ventricular (LV) function have not been quantified. METHODS AND RESULTS In an open-pericardium, paced (70 and 90 bpm) pig model of LV regional ischemia (left anterior descending coronary constriction), with high-fidelity LV, LA, and RV pressure recordings, we obtained the LA area with 2D automated border ...
متن کاملComplex left atrial appendage morphology and left atrial appendage thrombus formation in patients with atrial fibrillation.
BACKGROUND In patients with atrial fibrillation (AF), most thrombus forms in the left atrial appendage (LAA). However, the relation of LAA morphology with LAA thrombus is unknown. METHODS AND RESULTS We prospectively enrolled 633 consecutive patients who were candidates for catheter ablation for symptomatic drug-resistant AF. Transesophageal echocardiography (TEE) was performed to assess LAA ...

متن کاملImprovement of left atrial function and left atrial reverse remodeling after surgical treatment of atrial fibrillation.
Two-dimensional speckle tracking echocardiography (2D-STE) is an emerging technology for the evaluation of left atrial (LA) function. This technique is feasible, overcomes the limitations of tissue Doppler imaging and has been demonstrated to accurately assess atrial function during the different phases of the cardiac cycle (1). Atrial structural and electrical remodeling are the hallmarks of a...
