Background Establishment of the range of normal values and associated variations of two-dimensional (2D) speckle-tracking echocardiography (STE)–derived right ventricular (RV) strain is a prerequisite for its routine clinical application in…
Background This prospective study investigated whether the incorporation of myocardial contrast echocardiography (MCE) into a clinical stress echocardiography service reproduces the benefits of assessing myocardial perfusion proved previously in research…
Background Implementation of reliable noninvasive testing for screening cardiac allograft vasculopathy (CAV) is of critical importance. The most widely used modality, dobutamine stress echocardiography (DSE), has moderate sensitivity and specificity….
Noninvasive cardiac imaging is one of the pillars of clinical cardiology, with echocardiography being the most widely used imaging modality for assessing cardiovascular anatomy and function. In the United States…
Background Previous studies have demonstrated variable patterns of longitudinal septal deformation in patients with left ventricular (LV) dysfunction and left bundle branch block. This prospective single center study was designed…
Background Many patients with suspected non–ST-segment elevation acute coronary syndrome (NSTE-ACS) do not have significant coronary artery disease. The current diagnostic approach of repeated electrocardiography and cardiac biomarker assessment requires…
Background In normal subjects, left ventricular (LV) dimensions have been shown to decrease over time, while wall thickness is increasing. The aim of this study was to investigate LV remodeling…
Background The aim of this multicenter study was to determine the normal ranges and the clinical relevance of multidirectional systolic parameters to evaluate global left ventricular (LV) systolic function. Methods…
The importance of the left atrium in cardiovascular performance has long been acknowledged. Quantitative assessment of left atrial (LA) function is laborious, requiring invasive pressure-volume loops and thus precluding its…
Left Ventricular Mechanics The left ventricle undergoes complex deformations with contraction and relaxation that involve shortening, thickening, twisting, and torsion during systole in order to eject blood efficiently. The process…
