P775 Assessment of left ventricular function in patients with atrial fibrillation using real time triplain speckle tracking in comparison with 2D speckle tracking

Usefulness of left atrial speckle-tracking echocardiography in patients with atrial fibrillation

Methodological Gaps in Left Atrial Function Assessment by 2D Speckle Tracking Echocardiography

The assessment of left atrial (LA) function is used in various cardiovascular diseases. LA plays a complementary role in cardiac performance by modulating left ventricular (LV) function. Transthoracic two-dimensional (2D) phasic volumes and Doppler echocardiography can measure LA function non‑invasively. However, evaluation of LA deformation derived from 2D speckle tracking echocardiography (ST...

Assessment of left atrial-left ventricular-arterial coupling using 2-dimensional speckle tracking echocardiography.

by 2D-STE, and investigated the effect of cardiovascular risk factors on LA-LV-arterial coupling.1 In their multivariate linear regression analysis, peak early diastolic LV longitudinal strain rate (SR-LVe) and E/e’/S-LAs were independent predictors related to abdominal aortic stiffness in patients with cardiovascular risk factors. On the other hand, only age contributed to abdominal aortic sti...

Left atrial function examination of healthy individuals with 2D speckle-tracking imaging

The aim of the present study was to determine the left atrial (LA) function of healthy individuals of various ages by examining their LA strain and time-to-peak (TP) using 2D speckle-tracking imaging (2DSTI). In addition, the study investigated the potential value of STI in clinical applications. The 142 volunteers were divided into three age groups, namely, young adult, middle-aged and elderly...

Real-time Left Ventricular Speckle-Tracking in 3D Echocardiography With Deformable Subdivision Surfaces

In this paper, we extend a computationally efficient framework for real-time tracking of deformable subdivision surfaces in 3D echocardiography with speckle-tracking measurements to track material points. Tracking is performed in a sequential state-estimation fashion, using an extended Kalman filter to update the subdivision surface based on displacement vectors from 3D block-matching in the le...
