comparison of left atrial function between hypertensive patients with normal atrial size and normotensive subjects using strain rate imaging technique

Association Between the Left Atrial and Left Atrial Appendages Systole Strain Rate in Patients with Atrial Fibrillation

BACKGROUND The aim of this research was to explore the association between the left atrial (LA) and left atrial appendages (LAA) systole strain rate (SSR) in patients with atrial fibrillation (AF), and to provide evidence to aid in the assessment of disease progression. MATERIAL AND METHODS A total of 180 patients with AF were selected for the study (130 patients with paroxysmal AF (Par AF) and...

left atrial mechanics in hypertensive patients

Do left atrial strain and strain rate reflect intrinsic atrial function, or are they determined by left ventricular function?

BACKGROUND Left atrial (LA) strain (S) and strain rate (SR) are reported as measures of intrinsic function. AIM Since the LA and left ventricle (LV) are connected through the mitral annulus, we investigated: (1) if deformation indices in the LA are mostly predicted by deformation of the LV; (2) if timings of S and SR events are similar in both the LA and LV; and (3) if alteration of S and SR ...

radiofrequency 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...

Evaluation of the Relationship between Circadian Blood Pressure Variation and Left Atrial Function Using Strain Imaging

BACKGROUND Non-dippers were reported as showing different left atrial function, compared to dippers, but no study to date investigated the changes in the left atrial function according to the diurnal blood pressure pattern, using tissue Doppler and strain imaging. METHODS Forty never treated hypertensive patients between 30 and 80 years of age were enrolled in this study. Patients were classi...
