A Rising Paradigm of Appropriateness
Medical imaging overuse has been pinpointed as a key driver behind the overall escalating health care costs in the United States. Across widely separated and unmanaged populations, up to 50%…
Evaluation of the Clinical Application of the ACCF/ASE Appropriateness Criteria for Stress Echocardiography
Background The aim of this study was to evaluate the clinical application of the American College of Cardiology Foundation and American Society of Echocardiography appropriateness criteria for stress echocardiography (SE)…
Differences of Myocardial Systolic Deformation and Correlates of Diastolic Function in Competitive Rowers and Young Hypertensives: A Speckle-Tracking Echocardiography Study
Background The aim of this study was to compare speckle-tracking echocardiography–derived left ventricular (LV) systolic mechanics and their relationships with LV diastolic properties in young patients with hypertension and in…
Diagnostic Value of Segmental Longitudinal Strain by Automated Function Imaging in Coronary Artery Disease without Left Ventricular Dysfunction
Background The aim of this study was to investigate the role of segmental longitudinal strain for the diagnosis of coronary artery disease (CAD) assessed by automated function imaging. Methods One…
Advantage of Right Ventricular Outflow Tract Pacing on Cardiac Function and Coronary Circulation in Comparison with Right Ventricular Apex Pacing
Background The purpose of this study was to investigate the acute effect of right ventricular outflow tract (RVOT) pacing and right ventricular apex (RVA) pacing on synchronous ventricular activation and…
Different Determinants of Improvement of Early and Late Systolic Mitral Regurgitation Contributed after Cardiac Resynchronization Therapy
Background Functional mitral regurgitation (MR) at different phases of the regurgitant period may respond differently to cardiac resynchronization therapy (CRT). The aims of this study were to examine the impact…
Effect of Low-Amplitude Two-Dimensional Radial Strain at Left Ventricular Pacing Sites on Response to Cardiac Resynchronization Therapy
Background Left ventricular (LV) lead placement to areas of scar has detrimental effects on response to cardiac resynchronization therapy (CRT). Speckle-tracking radial two-dimensional strain offers assessment of the extent of…
Corrigendum
In the article entitled “Acute Thrombosis Formation as a Complication of Right Ventricular Biopsy” by Veress et al (J Am Soc Echocardiogr 2010;23:1039-44), one of the author’s names was incorrect….
Real-Time Three-Dimensional Echocardiographic Assessment of Left Ventricular Systolic Dyssynchrony in Healthy Children
Background The use of resynchronization therapy for the treatment of left ventricular (LV) systolic dysfunction in children has been expanding. Because QRS duration is not a reliable indicator of the…
Accuracy and Reproducibility of Strain by Speckle Tracking in Pediatric Subjects with Normal Heart and Single Ventricular Physiology: A Two-Dimensional Speckle-Tracking Echocardiography and Magnetic Resonance Imaging Correlative Study
Background Myocardial strain is a sensitive measure of ventricular systolic function. Two-dimensional speckle-tracking echocardiography (2DSE) is an angle-independent method for strain measurement but has not been validated in pediatric subjects….
