AIMS To evaluate the diagnostic power of abnormal global longitudinal strain (GLS) to detect non-obstructive coronary artery disease (CAD) in the resting echocardiogram. GLS using two-dimensional speckle-tracking echocardiography (2D STE) is a powerful tool for detecting advanced CAD. However, the diagnostic power of 2D STE for detecting moderate, clinically unapparent CAD from images obtained ...

BACKGROUND Two-dimensional (2D) echocardiography studies have shown that the maximum length of vegetation (MLV)≥10 mm is a predictor of embolic events (EEs) in patients with infective endocarditis. However, 2D measurements probably underestimate the vegetation dimensions. In this study, we evaluated the feasibility of real-time 3-dimensional transesophageal echocardiography (RT3DTEE) in determi...

conclusions in this study there is no correlation between the main lv diastolic indices derived by spect and echocardiography, may be due to the main changes in the last version of guidline for assessment of lv diastolic function by echocardiography. results the population study consisted of 19 male and 30 female with the average age of 58.2 years.there is a mild negative correlation between pf...

Methods 450 consecutive patients undergoing valvular were studied prospectively. Intraoperative 2D and 3D transesophageal echocardiographic (TEE) examinations were performed using a recently introduced TEE probe that provides realtime 3D imaging. Expert echocardiographers blinded to 2D TEE findings assessed the etiology of MR on 3D transesophageal echocardiography. Similarly, experts blinded to...

Hypertrophic cardiomyopathy (HCM) is a frequently recognized condition on echocardiography. The apical variant, also known as 'Japanese variant', is rare and often poses a diagnostic challenge. There has been a resurgence of interest in the diagnosis of HCM especially with the advent of novel imaging modalities such as strain imaging. Two-dimensional (2D) strain echocardiography calculates tiss...

In this paper we study the segmentation of coronary arteries from bidimensional echocardiography simulated images (phantoms) using Fuzzy Connectedness concepts implemented using Image Foresting Transform (IFT). This approach transforms the image into an oriented and weighted graph; therewith a graph-based algorithm can be applied to process the image segmentation. In echocardiographic scenario,...

AIMS Intracardiac echocardiography (ICE) and two-dimensional transoesophageal echocardiography (2D TEE) are used in most centres for guiding transcatheter atrial septal defect (ASD) closure. ASDs have complex shapes that are not well characterized with 2D imaging. Real-time 3D TEE (RT3D TEE) provides en-face visualization of the ASD, allowing precise assessment of ASD dimensions. Accordingly, o...
