Left atrial mechanical functions in chronic primary mitral regurgitation patients: a velocity vector imaging-based study
INTRODUCTION Assessment of the left atrium (LA) mechanical function provides further information on the level of cardiac compensation. We aimed to evaluate LA function using a strain imaging method: velocity vector imaging (VVI) in chronic primary mitral regurgitation (MR). MATERIAL AND METHODS We recruited 48 patients with chronic, isolated, moderate to severe MR (54.70 ±15.35 years and 56% ...
متن کاملLeft atrial mechanical functions in patients with anterior myocardial infarction: a velocity vector imaging-based study.
BACKGROUND The contribution of the left atrium (LA) to left ventricular (LV) function increases in myocardial infarction (MI). AIM To evaluate LA function by using volume measurements and a novel strain imaging method, namely velocity vector imaging (VVI), in patients with acute anterior MI. METHODS Twenty-four patients with previous anterior MI (aged 63.8 ± 4.2 years, 56% men) and 30 healt...
متن کاملLeft atrial function and deformation in chronic primary mitral regurgitation.
AIMS To study global and regional left atrial (LA) mechanics in chronic primary mitral regurgitation (MR) with echocardiography. METHODS AND RESULTS LA volumes during reservoir, conduit, and contractile phases were measured in 27 MR patients and 25 controls. LA ejection fraction (EF) and ejection force were calculated. Reservoir (SR-R), conduit (SR-C), and contractile phase (SR-A) strain rate...
متن کاملLeft Atrial and Right Atrial Deformation in Patients with Coronary Artery Disease: A Velocity Vector Imaging-Based Study
BACKGROUND Impaired left ventricular (LV) function has been shown by strain rate (SR) imaging in patients with coronary artery disease (CAD). Our aim was to investigate global and regional, systolic and diastolic left atrial (LA) and right atrial (RA) longitudinal deformation in CAD using velocity vector imaging. METHODS Echocardiographic and velocity vector imaging studies were performed in ...
متن کاملLeft atrial function in patients with mitral valve regurgitation.
The purpose of this study was to assess left atrial (LA) function and myocardial mechanics in patients with degenerative mitral regurgitation (MR). Eighty patients with degenerative MR and twenty control subjects were included prospectively. LA volume (LAV) and right atrial (RA) volume (RAV) were measured with three-dimensional transthoracic echocardiography at three phases of the cardiac cycle...
