Contrast-enhanced CMR in patients after percutaneous closure of the left atrial appendage: A pilot study [PDF]

, 2011
Background To evaluate the feasibility and value of first-pass contrast-enhanced dynamic and post-contrast 3D CMR in patients after transcatheter occlusion of left atrial appendage (LAA) to identify incorrect placement and persistent leaks.

Prevalence and significance of alterations in cardiac structure and function in patients with heart failure and a preserved ejection fraction [PDF]

, 2011
<p><b>Background:</b> The purpose of this study was to examine the prevalence of abnormalities in cardiac structure and function present in patients with heart failure and a preserved ejection fraction (HFPEF) and to determine whether ...

Left atrial structural and mechanical remodelling in heart failure with reduced ejection fraction

ESC Heart Failure, 2021
Aims In patients with heart failure with reduced ejection fraction (HFrEF), an association between left atrial (LA) dilatation and dysfunction is expected, but the degree of coexistence of the two abnormalities and their relative prognostic role is not ...

Atrial cellular electrophysiological changes in patients with ventricular dysfunction may predispose to AF [PDF]

, 2009
<b>Background:</b> Left ventricular systolic dysfunction (LVSD) is a risk factor for atrial fibrillation (AF), but the atrial cellular electrophysiological mechanisms in humans are unclear.

Sevoflurane effects on left atrial performance: a transesophageal echocardiographic study on patients undergoing coronary artery bypass grafting

Ain Shams Journal of Anesthesiology, 2023
Background Patients presenting for coronary artery bypass grafting often have left ventricular diastolic dysfunction. These patients are in need for a well contracting left atrium (LA) to generate the required cardiac output.

The left atrial function index: A rhythm independent marker of atrial function [PDF]

European Journal of Echocardiography, 2007
This study evaluates a simple echocardiographic rhythm independent expression of left atrial (LA) function, 'the left atrial function index' (LAFI).Quantitation of LA function is challenging and often established parameters including peak A are limited to sinus rhythm (SR).

Percutaneous or mini-invasive surgical radiofrequency re-ablation of atrial fibrillation: Impact on atrial function and echocardiographic predictors of short and long-term success

Frontiers in Cardiovascular Medicine, 2022
ObjectivesThe aim of this study was to compare percutaneous catheter ablation vs. minimally invasive surgical ablation, evaluating the impact of repeated ablation on atrial function, and evaluating predictors of atrial fibrillation (AF) recurrence ...

Left atrial eccentricity in chronic mitral regurgitation: relation to left atrial function [PDF]

European Heart Journal - Cardiovascular Imaging, 2012
The aim of this study was to assess the changes in the left atrial (LA) shape and to identify the determinants of these changes in chronic mitral regurgitation (MR).We enrolled 125 consecutive patients (56 ± 16 years, 51% men) with chronic MR caused by myxomatous mitral valve disease in sinus rhythm and 45 control patients (54 ± 15 years, 55% men ...
