Native tissue second harmonic imaging improves endocardial and epicardial border definition in dobutamine stress echocardiography.
AIMS Native tissue second harmonic imaging (SHI) implemented in two-dimensional (2D) echocardiography was found to improve left ventricular (LV) endocardial border delineation. Dobutamine stress echocardiography (DSE) depends on the ability to adequately visualize these borders. We analysed whether SHI, compared to fundamental imaging (FI), can improve echogenicity qualitatively and quantitativ...
متن کاملDobutamine stress echocardiography and tissue synchronization imaging.
Dobutamine stress echocardiography has emerged as a reliable method for the diagnosis of coronary artery disease and the management of its treatment. Several studies have shown that that this technique works with 80-85% accuracy in comparison with other imaging methods. There are few studies aimed at developing the clinical utility of dobutamine stress echocardiography for the evaluation of nor...
متن کاملNon-contrast second harmonic imaging improves interobserver agreement and accuracy of dobutamine stress echocardiography in patients with impaired image quality.
OBJECTIVE To examine the influence of second harmonic imaging during dobutamine echocardiography on regional endocardial visibility, interobserver agreement in the interpretation of wall motion abnormalities, and diagnostic accuracy in patients with reduced image quality. DESIGN Blinded comparison. SETTING Tertiary care centre. PATIENTS 103 consecutive patients with suspected coronary art...
متن کاملImproved identification of viable myocardium using second harmonic imaging during dobutamine stress echocardiography.
OBJECTIVE To determine whether, compared with fundamental imaging, second harmonic imaging can improve the accuracy of dobutamine stress echocardiography for identifying viable myocardium, using nuclear imaging as a reference. PATIENTS 30 patients with chronic left ventricular dysfunction (mean (SD) age, 60 (8) years; 22 men). METHODS Dobutamine stress echocardiography was carried out in al...
متن کاملDobutamine stress echocardiography.
Two-dimensional echocardiography is a versatile, accurate, and readily available method for the assessment of cardiac anatomy and function, and extensive experience has been gained in the analysis of left ventricular wall motion. Using modern imaging techniques, regional as well as global wall motion analysis can be performed. Echocardiography can be used in conjunction with a protocol for eith...
