Left Atrial Size and Function in a Canine Model of Chronic Atrial Fibrillation and Heart Failure
BACKGROUND Our aim was to assess how atrial fibrillation (AF) induction, chronicity, and RR interval irregularity affect left atrial (LA) function and size in the setting of underlying heart failure (HF), and to determine whether AF effects can be mitigated by vagal nerve stimulation (VNS). METHODS HF was induced by 4-weeks of rapid ventricular pacing in 24 dogs. Subsequently, AF was induced ...
متن کاملRelation between echocardiographically determined left atrial size and atrial fibrillation.
In an attempt to define quantitatively the relation between left atrial size and atrial fibrillation, echocardiography was used to study 85 patients with isolated mitral valve disease, 50 patients with isolated aortic valve disease, and 130 patients with asymmetric septal hypertrophy. In all three groups of patients, atrial fibrillation was rare when left atrial dimension was below 44 mm (3 of ...
متن کاملLeft Atrial Size and Function in Hypertrophic Cardiomyopathy Patients and Risk of New-Onset Atrial Fibrillation.
BACKGROUND The value of left atrial (LA) diameter, volume, and strain to risk stratify hypertrophic cardiomyopathy patients for new-onset atrial fibrillation (AF) was explored. METHODS AND RESULTS A total of 242 hypertrophic cardiomyopathy patients without AF history were evaluated by (speckle-tracking) echocardiography. During mean follow-up of 4.8±3.7 years, 41 patients (17%) developed new-...

متن کاملImprovement of left atrial function and left atrial reverse remodeling after surgical treatment of atrial fibrillation.
Two-dimensional speckle tracking echocardiography (2D-STE) is an emerging technology for the evaluation of left atrial (LA) function. This technique is feasible, overcomes the limitations of tissue Doppler imaging and has been demonstrated to accurately assess atrial function during the different phases of the cardiac cycle (1). Atrial structural and electrical remodeling are the hallmarks of a...
