The left atrial (LA) appendage is a common source of cardiac thrombus formation associated
with systemic embolism. Transesophageal echocardiography allows a detailed evaluation of …

Atrial conduction disorders are frequent in elderly subjects and/or those with structural heart
diseases, mainly mitral valve disease, hyperthrophic cardiomyopathies, and hypertension …

Background—Considerable controversy exists regarding impairment of cardiac function in
diabetes mellitus (DM). We investigated the serial changes in left ventricular (LV) …

Aims: Left atrial function is abnormal in a wide range of cardiac diseases. This study was
designed to assess the effects of normal ageing and sex on left atrial morphology and …

The hypotheses of this prospective study were that (1) left atrial appendage (LAA) blood flow
velocities can be recorded in cats with myocardial disease by transthoracic Doppler …

Previous studies have shown that abnormal mitral flow patterns and left atrial (LA)
enlargement are independently associated with survival in patients with left ventricular (LV) …

Aims: Assess the value of peak atrial systolic mitral annular velocity (A ann) measured by
Doppler tissue echocardiography to quantify left atrial systolic function. Methods: We studied …

Background: Left atrial appendage (LAA) contraction velocities are used frequently as
surrogates of global left atrial (LA) function, but the validity of this approach has not been …

The left atrial (LA) appendage contracts both actively and passively throughout the cardiac
cycles. 1, 2 Previous clinical and experimental data have shown that function of this structure …

The objectives of this study were to establish reference values and define the determinants
of left atrial appendage (LAA) flow velocities in the general population. LAA flow velocities …
