Isolation of the pulmonary veins (PVI) has become a mainstay in atrial fibrillation (AFib) therapy. Lesions in left atrial tissue lead to scar formation and this may affect left atrial function.

This article discusses the traditional and more recent echocardiographic measures that have been employed to evaluate atrial function. Conventional parameters commonly used and reported in the literature include the study of the various phases of atrial activity using atrial volume measurements, the peak A wave velocity, its velocity time integral (VTI)

Atrial receptors and renal function
Physiological Reviews, 1975The hypothesis that receptors in the heart or pulmonary vasculature initiate a reflex that influences urine flow was derived from experiments designed to evaluate the effect of mechanical ventilation on renal function. These experiments indicated that urine flow usually decreases during positive-pressure breathing and usually increases during negative-

Atrial function after cardioversion
American Heart Journal, 1967Abstract The immediate hemodynamic changes occurring after D.C. cardioversion have been measured in 18 patients with rheumatic, ischemic, or thyrotoxic heart disease. Sinus rhythm was successfully restored in 13 patients. Twelve out of 13 successfully cardioverted patients developed clearly visible right atrial “a” waves.

Fibrinolytic function and atrial fibrillation
Thrombosis Research, 2003Atrial fibrillation (AF) is the commonest sustained cardiac arrhythmia, which is associated with a substantial risk of stroke and thromboembolism. A prothrombotic or hypercoagulable state has been observed in these patients, although previous studies have mainly focused on various clotting factors, endothelial damage or dysfunction markers and platelet

Left atrial phasic function: physiology, clinical assessment and prognostic value
Heart, 2023Left atrial (LA) phasic function provides significant insights into the pathophysiology of cardiovascular disease. LA function is described in three phases: reservoir (atrial filling, during systole), conduit (passive emptying, during early diastole) and

Left atrial and left atrial appendage function in paroxysmal atrial fibrillation
Acta Physiologica Hungarica, 2011In patients with paroxysmal atrial fibrillation (PAF) little information is available about left atrial (LA)function, and there is less information about LA appendage (LAA) function, and about their relations.46 patients were selected for catheter ablation (CA) because of nonvalvular PAF.Transthoracic, tissue Doppler and transoesophageal ...

Atrial Contractile Function in Patients With Paroxysmal Atrial Fibrillation
Kardiologiia, 2015The aim of study was to investigate atrial contractile function in patients with paroxysmal atrial fibrillation (AF) in sinus rhythm using transthoracic echocardiography.35 patients with paroxysmal AF and arterial hypertension (mean age 62 ± 10 years, 43% males) were enrolled in the study. Control group was composed of comparable patients with arterial

The atria are thin walled chambers that play an important role in ventricular filling. Assessment of atrial dimensions and function has important clinical and prognostic implications. Initial M-mode and 2-dimensional linear measurements have progressed to area and then volumetric measurements, followed by 3-dimensional measurements, providing superior ...

Left atrial volume and function in patients with atrial fibrillation
Current Opinion in Cardiology, 2014This review of emerging approaches to left atrial imaging in atrial fibrillation is relevant because there has been considerable recent development in the noninvasive characterization of left atrial structure and function. Concurrently, the identification and treatment of atrial fibrillation and the prevention of thromboembolism are evolving.
