BACKGROUND Transesophageal echocardiography (TEE) is often still considered the echocardiographic test of choice in the general ICU patient population to establish the presence or absence of cardiac cause of shock, and is often requested and performed as the initial and only echocardiographic test. This premise is based on older studies in which(More)
BACKGROUND The primary determinate for the indication of cardiac resynchronization therapy in symptomatic chronic heart failure currently is a prolonged QRS duration. This is based on the premise that a prolonged QRS duration is a marker of left ventricular (LV) dyssynchrony. Tissue synchronization imaging (TSI) is an emerging technology that uses tissue(More)
AIMS To determine whether the degree of untwisting of the apex in early diastole is related to established parameters of diastolic function. METHODS AND RESULTS Data from 71 hospital inpatients with preserved left ventricular systolic function who underwent standard two-dimensional echocardiography was analysed using an off-line speckle tracking software(More)
PURPOSE Right ventricular (RV) systolic function as measured by right ventricular ejection fraction (RVEF) has long been recognized as an important predictor of outcome in heart failure patients. The echocardiographic measurement of RV volumes and RVEF is challenging, however, owing to the unique geometry of the right ventricle. Several nonvolumetric(More)
Recently it has been demonstrated that high resolution transthoracic echocardiography (HRTTE) is able to detect differences in the wall thickness of the left anterior descending coronary artery (LAD) between patients with coronary artery disease (CAD) and normal volunteers. We sought to validate this technique, develop a normal range of values and(More)
OBJECTIVE We sought to objectively quantify the independent impact of significant mitral regurgitation (MR) on prognosis in patients with multiple comorbidities and ascertain the extent to which median survival is affected by increasing comorbidities. METHODS This was a retrospective matched cohort study using a clinical-echocardiography reporting(More)

AIMS The aims of this study were (1) to evaluate the relationship between novel two-dimensional transthoracic indices of left atrial (LA) mechanical function (speckle-tracking- and tissue Doppler-derived parameters), conventional indices (A-wave peak velocity and velocity-time integral, and A' velocity), and transoesophageal echocardiographic parameters (LA(More)
