Left atrial volumes and associated stroke subtypes [PDF]

BMC Neurology, 2013
Abstract Background Cardio embolism and cerebrovascular atherosclerosis are two major mechanisms of stroke. Studies investigating associations between advanced echocardiographic parameters and stroke mechanisms are limited.

Left atrial volume and function by transthoracic echocardiography [PDF]

European Journal of Echocardiography, 2011
We read with interest the article by Donal et al. 1 regarding the function of the left atrium (LA) in patients treated for atrial fibrillation. In the Methods section, the echocardiographic assessment of LA surface areas and the derivation of the LA emptying fraction from the corresponding …

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.

Left atrial volume quantification using cardiac MRI in atrial fibrillation: comparison of the Simpson’s method with biplane area-length, ellipse, and three-dimensional methods [PDF]

, 2013
PURPOSELeft atrial volume is an important predictor of future arrhythmias, and it can be assessed by several different methods. Simpson’s method is well accepted as a reference standard, although no standardization exists for cardiac magnetic resonance ...

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 ...

Determination of Left Atrial Volume by Angiocardiography

Japanese Circulation Journal, 1970
Left atrial volume and its change during cardiac cycle were studied in 49 patients with various heart diseases and 8 normal individuals by simultaneous use of cineangiocardiography at 400 fps and film changer at 6 fps. Methods Calculation of left atrial volume was performed as described by Sauter et al.

Persistence of left atrial abnormalities despite left atrial volume normalization after successful ablation of atrial fibrillation

Journal of Arrhythmia, 2021
Background Left atrial volume index (LAVI) of >34 mL/m2 is the cutoff value for identifying an enlarged left atrium. The definition of left atrial (LA) reverse remodeling after atrial fibrillation (AF) ablation is undetermined.

Left Atrial Volume in Normal Japanese Adults

Circulation Journal, 2006
Two-dimensional (D) echocardiography-derived left atrial (LA) volume has been shown to provide a more accurate assessment of LA size than the M-mode LA dimension. Our objective was to provide reference ranges of LA volume in healthy Japanese adults.The study subjects consisted of 105 Japanese adults, with a mean age of 39+/-13 years (range 20-63 years ...

Left Atrium Volume Index Profile in Diastolic Dysfunction

Majalah Kardiologi Indonesia, 2013
Background. Diastolic dysfunction is frequently found in hypertension,usually accompanied with left ventricular hypertrophy. Several parameter was developed to assess the diastolic function including left atrial volume index, E/A, DT, IVRT, S/D, E/e ...
