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 ...

Preserved Left Atrial Function Following Left Atrial Appendage Closure for Stroke Prevention

Journal of Invasive Cardiology, 2021
Patients with atrial fibrillation (AF) are at high risk of thromboembolism, with most thrombi forming in the left atrial (LA) appendage. LA appendage closure is an alternative therapy to oral anticoagulation for stroke prevention in AF patients with contraindication to oral anticoagulation.

Impact of atrial fibrillation on left atrial reservoir function

Journal of Echocardiography
BACKGROUND: Left atrial (LA) reservoir function is an important determinant of left ventricular (LV) filling. While atrial fibrillation (AF) has been suggested to impair LA function, the impact of atrial fibrillation on left atrial reservoir function, in comparison with normal sinus rhythm (NSR), has not been fully elucidated METHODS: We studied 40 ...

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.

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 ...

Descriptive analysis of instantaneous left atrial volume—with special reference to left atrial function

Journal of Surgical Research, 1981
Abstract Instantaneous left atrial volume was determined in five calves by electrical integration of left atrial differential flow (pulmonary vein flow less mitral valve flow). Volume changes were classified and compared to previously described mitral valve flow phases.

Assessment of left atrial function in diabetes mellitus by left atrial volume tracking method

Journal of Huazhong University of Science and Technology [Medical Sciences], 2010
The value of the left atrial volume tracking (LAVT) method in the evaluation of left atrial (LA) function in patients with diabetes mellitus (DM) was examined in this study. Fifty-eight DM patients as DM group and 40 healthy people as normal control group were enrolled in this study.

Impact of left atrial appendage occlusion on left atrial function—The LAFIT Watchman study

Journal of Interventional Cardiac Electrophysiology, 2019
Left atrial (LA) strain and strain rate (SR) analysis by two-dimensional speckle tracking echocardiography is a novel way of LA function assessment. From prior study, we know that LA appendage closure with LARIAT appears to improve LA function.The purpose of this study was to assess the impact of LAA closure via Watchman device on LA function via ...
