BACKGROUND This study attempted to identify the role of combined conventional and novel echocardiographic techniques in evaluation of left atrial (LA) function to predict the postoperative atrial fibrillation (POAF). METHODS In this cross-sectional study, subjects with sinus rhythm who were candidates for CABG were enrolled. Preoperative LA function was evaluated by conventional echocardiogra...

Echocardiography is the most common diagnostic tool for patients with heart disease, providing detailed information about cardiovascular morphology and hemodynamics previously available only by angiography and catheterization. It is noninvasive, widely available and inexpensive. With its huge evidence base, echocardiography has a central position in modern cardiac diagnosis and management. Rece...

OBJECTIVE The aim of this study was to apply speckle tracking imaging (STI) to evaluate rabbit sepsis induced myocardial injury. MATERIALS AND METHODS Rabbits were injected with the endotoxin lipopolysaccharide (LPS). before and 2h, 4h, 6h, 8h, 12h after the injection of LPS, conventional echocardiography and STI were performed to measure left ventricular end diastolic diameter (LVDd), end-sy...

Advanced high strength steels (AHSS) have recently attracted great attention because of their superior mechanical properties. A modern group of these steels, known as twinning induced plasticity (TWIP) steels, shows a unique combination of strength and ductility even at high rates of strain. In order to examine the functionality of such steels in dynamic loading conditions, their mechanical beh...

BACKGROUND Amyloidosis is a disease caused by deposits of insoluble fibrils in extracellular spaces. The most common type of familial amyloidosis is mediated by mutation of transthyretin, especially Val30Met. Symptoms and ejection fraction decrease may occur in cardiac amyloidosis only in case of poor prognosis. Myocardial strain detected by two-dimensional speckle tracking echocardiography can...

BACKGROUND AND OBJECTIVES Assessment of left ventricle (LV) function by using strain and strain rate is popular in the clinical setting. However, the use of these echocardiographic tools in assessing right ventricle (RV) failure, and the manner in which they both reflect the functional capacity of the patient, remains poorly understood. This study aimed to investigate the change in exercise cap...
