Background In congenitally corrected transposition of the great arteries (cc-TGA), the morphologic right ventricle acts as the subaortic (systemic) ventricle, and deterioration of the ventricle over time is a well-known…
Background Although retrospective studies have suggested that myocardial perfusion and wall motion analysis with real-time myocardial contrast echocardiography (RTMCE) improves the detection of coronary artery disease (CAD) during dobutamine or…
Background Evaluation of myocardial deformation by two-dimensional speckle-tracking is useful for clinical and research purposes. However, differences may exist among different ultrasound machines, software packages, frame rates, and observers. Methods…
Background Multiple vendor-specific two-dimensional speckle-tracking echocardiographic algorithms with which to characterize myocardial mechanics are commercially available. The purpose of this study was to compare global longitudinal strain (GLS) results between…
Background Quantitative analysis of segmental myocardial deformation of different myocardial layers has become possible using strain-encoded cardiac magnetic resonance imaging (SENC) and speckle-tracking echocardiography (STE). We evaluated and compared the…
For more than a decade, myocardial strain has been in research use in the evaluation of cardiac ischemia and infarction and myocardial diseases and in the assessment of synchrony. In…
Background The 2007 appropriate use criteria (AUC) for echocardiography were revised in 2011 to cover a wider range of scenarios of use. The aim of this study was to compare…
Background The 2007 Appropriate Use Criteria (AUC) for echocardiography was revised in 2011 to cover a wider range of scenarios of use. Previous studies of the 2007 AUC found a…
Background The aim of this study was to compare appropriateness designations as determined by the updated 2011 appropriate use criteria (AUC) for echocardiography with prior versions of the AUC for…
Cardiologists and oncologists today face the daunting challenge of identifying patients at risk for late-onset left ventricular (LV) systolic dysfunction from the use of various chemotherapeutic agents. Currently, the most…
