Left atrial function: pathophysiology, echocardiographic assessment, and clinical applications.
PATHOPHYSIOLOGY OF LEFT ATRIAL MECHANICAL FUNCTION Atrial function, in a close interdependence with left ventricular (LV) function, plays a key role in maintaining an optimal cardiac performance. The left atrium (LA) modulates LV filling through its reservoir, conduit, and booster pump function, whereas LV function influences LA function throughout the cardiac cycle. The LA can act to increase ...
متن کاملLeft atrium function assessment by echocardiography - physiological and clinical implications.
Left atrium enlargement is a pathophysiological response to volume and pressure overload associated with a wide range of cardiovascular disorders leading to left ventricle systolic and diastolic dysfunction. Physiological factors contribute to significant differences in left atrium size in normal individuals. Moreover, left atrium enlargement was shown to have a significant prognostic value for...
متن کاملLeft atrial appendage function assessment and thrombus identification☆
BACKGROUND The diagnosis of thrombus in the left atrium in patients with persistent atrial fibrillation (AF) and may be inconsistent because of variability in thrombus morphology. In some cases it is challenging and requires unusual approach. New Doppler-derived methods might be helpful to identify such thrombi. We evaluated quantitative differences in mechanical function of the left atrial app...
متن کاملAssessment of left atrial appendage function by transesophageal echocardiography. Implications for the development of thrombus.
BACKGROUND The predilection of the left atrial appendage (LAA) for thrombus formation has long been known. METHODS AND RESULTS We prospectively studied the two-dimensional echocardiographic and Doppler patterns of LAA function in 82 patients by transesophageal echocardiography. In the 63 patients in sinus rhythm, LAA area was measured during LAA diastole at the onset of the electrocardiograph...
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 ...
