Em atletas de alta performance, principalmente aqueles que praticam esportes de resistência com treinos de alta intensidade e longa duração, o coração sofre alterações elétricas, funcionais e estruturais, aumentando a probabilidade de arritmias ventriculares e atriais. Sabe-se que esses atletas p...
BACKGROUND: Functional mitral regurgitation (FMR) is associated with dilated cardiomyopathy (DC), heart failure (HF), and worsening left atrial function (LAF). Patients with DC and FMR may present left atrial dysfunction resulting from both ventricular dysfunction and valve disease, but it is unknown whe...
SUMMARY OBJECTIVE: Myocardial speckle-tracking echocardiography can detect subtle abnormalities in the left atrial function. In this study, we aimed to investigate the relationship between left atrial myocardium and tissue function n assessed by two-dimensional speckle-tracking echocardiography and the...
RESUMEN Un corazón con tres aurículas, que sumaba cinco cámaras en total, fue un hecho que sorprendió a la medicina hace ya más de un siglo. Este raro defecto cardíaco congénito tiene muy baja incidencia, lo cual hace que sea muy poco conocido por las jóvenes generaciones de médicos dedicados a ...
Background: Four-dimensional echocardiography technique results in marked improvements in terms
of quality and accuracy in assessing the size and function of heart chambers, especially the left atrium
as its geometric variation has a notable impact on the results when using traditional echocardiographic
...
The present study evaluated the volume and function of the left atrium by two-dimensional echocardiographic feature-tracking imaging (2D-FTI) and Simpson’s monoplanar modeling in dogs with asymptomatic degenerative mitral valve disease (DMVD). The study consisted of 80 dogs that were divided into the f...
ABSTRACT Background Left atrial (LA) enlargement is a reliable predictor of adverse cardiovascular events, and reduced atrial function is an independent risk factor for mortality in patients with amyloidosis. The objective of this study was to characterize the LA function in Mexican patients with a conf...
Abstract Background: New echocardiographic techniques are used in the diagnosis and prognosis of many heart diseases. However, reference values in different populations are still needed for several of these new indexes. We studied these new echocardiographic parameters in a group of Brazilians with no k...
