Background Postsystolic shortening is a sensitive maker of myocardial ischemia. The aim of this study was to investigate whether diastolic dyssynchrony imaging is useful for the objective interpretation of dobutamine…
Have you earned credits for continuing medical education (CME) by reading the Journal of the American Society of Echocardiography (JASE)? If you have not, then you have been missing out…
Background Two-dimensional and Doppler echocardiography are standard methods to assess the severity of pulmonic insufficiency (PI). However, methods to define severity of PI – including the current published guidelines –…
Background The pulmonary valve (PV) is rarely visualized in short axis with conventional two-dimensional transthoracic echocardiography (TTE). Thus, the true incidence of abnormal PV morphology in patients undergoing TTE is…
Background Aortic stenosis leads to left ventricular hypertrophy and accumulation of fibrillar collagens. The analysis of integrated backscatter (IBS) parameters provides information on ultrasonic myocardial properties. Methods The study population…
Background Doppler-derived hemodynamic data for normal tricuspid valve bioprostheses are limited. Methods A comprehensive retrospective Doppler echocardiographic assessment of 285 normal Carpentier-Edwards Duraflex, Medtronic Mosaic, St. Jude Medical Biocor, Carpentier-Edwards…
In this issue of JASE , Fijalkowski et al. describe an improvement in myocardial reflectivity induced by aortic valve replacement (AVR) in severe aortic stenosis (AS), using integrated backscatter (IBS) analysis,…
Objective This multicenter study consisted of echocardiographic examination of subjects with stage A heart failure (HF) with cardiovascular risk factors and normal electrocardiogram and clinical examination results to (a) define…
Background While using echocardiography to guide endomyocardial biopsy (EMB), the authors have identified acute intracardiac thrombus formation related to the procedure, a hitherto unreported complication. The aims of this study…
Background The risk stratification of patients with left ventricular (LV) dysfunction can be performed using echocardiographic parameters such as the ejection fraction (EF). Recently, new technologies based on deformation measurements…
