Altered excitation-contraction coupling in human chronic atrial fibrillation [PDF]
, 2012 This review focuses on the (mal)adaptive processes in atrial excitation-contraction coupling occurring in patients with chronic atrial fibrillation. Cellular remodeling includes shortening of the atrial action potential duration and effective refractory ...

The Southwest Respiratory and Critical Care Chronicles, 2017 The left atrium (LA) is a left posterior cardiac chamber which is located adjacent to the esophagus. It is separated from the right atrium by the inter-atrial septum and connected to the left ventricle by the mitral valve apparatus.

[Evaluation of atrial function by echocardiography].
Giornale italiano di cardiologia (2006), 2007 In cardiology, ventricular function has extensively been studied, whereas atrial function received less attention. For such a reason atrial function is less known. The aim of this review was to summarize the role of atrial function and to explain how echocardiography and new echocardiographic-derived techniques may be of help to better study atrial ...

Post-operative atrial fibrillation is influenced by beta-blocker therapy but not by pre-operative atrial cellular electrophysiology [PDF]
, 2006 We investigated whether post-cardiac surgery (CS) new-onset atrial fibrillation (AF) is predicted by pre-CS atrial cellular electrophysiology, and whether the antiarrhythmic effect of beta-blocker therapy may involve pre-CS pharmacological remodeling ...

Atrial Size and Function in Athletes [PDF]
International Journal of Sports Medicine, 2015 We wanted to explore whether change in LA (left atrium) size would influence LA function, or increase regurgitation in the atrioventricular valves. 595 male elite football players and 47 non-athletic controls were included. End-systolic LA volume and RA area and end-diastolic LV volume and RV area were measured by 2-dimensional (2D) echocardiography ...

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).

Atrial fibrillation and left atrial size and function: a Mendelian randomization study [PDF]
Scientific Reports, 2021 AbstractAtrial fibrillation (AF) patients have enlarged left atria (LA), but prior studies suggested enlarged atria as both cause and consequence of AF. The aim of this study is to investigate the causal association between AF and LA size and function.

Frontiers in Cardiovascular Medicine, 2023 Changes in atrial size and function have historically been considered a surrogate marker of ventricular dysfunction. However, it is now recognized that atrial cardiomyopathy (ACM) may also occur as a primary myocardial disorder.
