Left Atrial Mechanics and Functional Capacity in HFpEF pts with Paroxysmal Atrial Fibrillation
نویسندگان
چکیده
Introduction: Patients (pts) with paroxysmal atrial fibrillation are at risk for developing heart failure preserved ejection fraction(HFpEF) and often have an impaired exercise capacity. Since left (LA) pressure plays a major role in the intolerance, we aimed to characterize contribution of resting LA mechanical properties, assessed by two-dimensional speckle tracking echocardiography upon

Left atrial appendage aneurysm with paroxysmal atrial fibrillation.
Aneurysm of the left atrial appendage is extremely rare, and afflicted patients most commonly present with atrial tachyarrhythmia or thromboembolism. For these patients, resection of the aneurysm is the recommended and preferred therapy. We present the case of a 57-year-old woman who was found incidentally to have a large aneurysm of the left atrial appendage presenting as atrial fibrillation. ...
متن کاملCanine model of paroxysmal atrial fibrillation and paroxysmal atrial tachycardia.
Both autonomic nerve activity and electrical remodeling are important in atrial arrhythmogenesis. Therefore, dogs with sympathetic hyperinnervation, myocardial infarction (MI), and complete atrioventricular block (CAVB) may have a high incidence of atrial arrhythmias. We studied eight dogs (experimental group) with MI, CAVB, and sympathetic hyperinnervation induced either by nerve growth factor...
متن کاملradiofrequency atrial fibrillation ablation technique in patients with mitral valve surgery and left atrial reduction procedures
background: about half of all patients who undergo mitral valve surgery suffer from atrial fibrillation (af). cox described the surgical cut-and-sew maze procedure, which is an effective surgical method but has some complications. this study was designed to evaluate the efficacy of a substitution method of radiofrequency ablation (rfa) for patients undergoing mitral valve surgery with af. metho...
متن کاملCorrelation between left atrial appendage morphology and flow velocity in patients with paroxysmal atrial fibrillation.
AIMS Reduction of left atrial appendage (LAA) flow velocity (FV) is a risk factor for thrombus formation and increases the risk of stroke in patients with atrial fibrillation (AF). Furthermore, LAA morphology is correlated with stroke in patients with AF. The aim of this study was to correlate LAAFV with LAA morphology in patients with AF. METHODS AND RESULTS We studied 96 patients (age 59.0 ...
متن کاملLeft Atrial Mechanical Function and Stiffness in Patients with Paroxysmal Atrial Fibrillation
BACKGROUND Abnormalities in the left atrial (LA) structure and function may develop in patients with paroxysmal atrial fibrillation (AF). We sought to determine the contribution of LA mechanical function, including LA stiffness, to AF by comparing patients with paroxysmal AF with normal control subjects, and to evaluate whether LA mechanical function and stiffness are related with the structura...
