Assessment of left atrial appendage function after cardioversion of atrial fibrillation: Relation to left atrial mechanical function

American Heart Journal, 1998
Although several flow patterns in the left atrial appendage have been described, mechanical determinants of its function have not been elucidated in human beings. We attempted to investigate changes in left atrial appendage function after cardioversion of atrial fibrillation and examine the potential relation between appendage function and left atrial ...

Effect of left atrial circumferential ablation for atrial fibrillation on left atrial transport function

Heart Rhythm, 2005
The effects of left atrial (LA) circumferential ablation on LA function in patients with atrial fibrillation (AF) have not been well described.The purpose of this study was to determine the effect of LA circumferential ablation on LA function.Gated, multiphase, dynamic contrast-enhanced computed tomographic (CT) scans of the chest with three ...

Left atrial function index and left atrial electromechanical functions in anxiety disorders

Acta Cardiologica
There is a close linkage between anxiety disorders (ADs), and development of cardiovascular disease (CVD) and atrial fibrillation (AF). We aimed to investigate left atrial function index (LAFI) and its components, LA mechanical functions and atrial conduction times in AD patients and age- and gender-matched control group patients for the first time in ...

Left atrial mechanical functions in pre‐eclampsia

Journal of Obstetrics and Gynaecology Research, 2005
AbstractAim: To assess the effect of short‐term pressure overload on left atrial (LA) mechanical function in pre‐eclampsia.Methods: Twenty women with pre‐eclampsia and 17 age‐matched healthy pregnant women were included. LA volumes were measured echocardiographically at the time of mitral valve opening (Vmax), onset of atrial systole (p‐wave at the ...

Left Atrial Function After Ablation for Paroxysmal Atrial Fibrillation

The American Journal of Cardiology, 2009
Radiofrequency ablation of the pulmonary veins has been used to treat patients with paroxysmal atrial fibrillation (AF), and atrial damage after ablation is an issue of concern. To evaluate left atrial function shortly and midterm after ablation, 33 consecutive patients with paroxysmal AF were studied at baseline, 24 hours, and > or =6 months after ...

Frequent premature atrial contractions impair left atrial contractile function and promote adverse left atrial remodeling

Echocardiography, 2018
ObjectivesThis study assessed if frequent premature atrial contractions (PACs) were associated with decreased left atrial (LA) strain and adverse remodeling.BackgroundLeft atrial dysfunction and enlargement increases risk of stroke. If frequent PACs cause LA dysfunction and remodeling, PAC suppressive therapy may be beneficial.MethodsInclusion criteria

Left atrial transport function.

Transactions of the American Clinical and Climatological Association, 1981
These studies show that the left atrial booster pump action serves as a supercharger which can increase left ventricular stroke volume in the range of 25 percent; and in patients with aortic stenosis, stroke work in the range of 50 percent (4).

Left ventricular and left atrial function

2015
Global left ventricular (LV) function is an important prognostic parameter and is useful for therapeutic decision-making. Since its introduction, two-dimensional (2D) echocardiography has played an important role in the quantitation of LV function.

ASSOCIATION ANALYSIS BETWEEN LEFT ATRIAL FUNCTION AND LEFT ATRIAL APPENDAGE FUNCTION IN PATIENTS WITH NONVALVULAR ATRIAL FIBRILLATION

Journal of the American College of Cardiology, 2019
The left atrial appendage (LAA) is a common source of cardiac thrombus with nonvalvular atrial fibrillation(NVAF). It is unclear about the relationship between left atrial (LA) function and LAA function in patients with NVAF.
