Background Functional analysis of the right ventricle cannot be reliably evaluated by conventional echocardiography, because of its complex geometry and load dependence of ejection phase indices. The Tei index, dP/dt,…
One of the objectives under our ASE goal of “increasing dissemination of cardiovascular quality standards across the globe,” is the inclusion of ASE’s guidelines in new global education efforts. The…
Background Differences in single right ventricle (SRV) and single left ventricles (SLV) function are poorly described, although myocardial dysfunction is an important risk factor for morbidity and mortality. The aims…
Patricia A. Pellikka, MD, FASE As part of its strategic plan, ASE has established a goal of positioning cardiovascular ultrasound as the cardiovascular imaging “test of choice” in the new…
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…
