3D Echocardiography of the LV and RV
The evaluation of the global and regional left ventricular (LV) function is an essential part of a routine perioperative TEE-examination. To date, the assessment of the LV ejection fraction (EF) is mainly performed by “eye-balling”, which relies on the echocardiographer’s experience and ability to visually integrate spatial information. Further limitations of 2D-TEE assessment of the LV EF are ...
متن کاملIncremental value of CMR over echocardiography for assessment of LV diastolic function
Background Incidence of heart failure with preserved ejection fraction is increasing and putting the emphases on comprehensive evaluation of diastolic function. Furthermore, diastolic dysfunction even in the absence of heart failure has been shown to have prognostic significance. American Society of Echocardiography and European Association of Echocardiography (ASE/EAE) 2-level decision tree us...
متن کاملSerial monitoring of LV function following chemotherapy: assessment using advanced echocardiography and cardiovascular magnetic resonance
Background Patients receiving anthracyclines (A) and herceptin (H) for treatment of breast cancer require serial monitoring of LV function. Although CMR is considered the gold standard for assessment of volumes and function, most tertiary institutions rely on echocardiography or gated heart pool scans. 2D transthoracic echocardiographic (TTE) image quality relies on appropriate acoustic windows...
متن کاملMRI assessment of LV relaxation by untwisting rate
Dong, Sheng-Jing, Paul S. Hees, Cynthia O. Siu, James L. Weiss, and Edward P. Shapiro. MRI assessment of LV relaxation by untwisting rate: a new isovolumic phase measure of t. Am J Physiol Heart Circ Physiol 281: H2002–H2009, 2001.—Most noninvasive measures of diastolic function are made during left ventricular (LV) filling and are therefore subject to “pseudonormalization,” because variation i...
متن کاملQuantification of LV Volumes with 4D Real-Time Echocardiography
This paper presents a new 4D (3D + Time) expansion of echocardiographic volumes on complex exponential wavelet-like basis functions called Brushlets [1]. Brushlet functions offer good localization in time and frequency and decompose a signal into distinct patterns of oriented textures, invariant to intensity and contrast range. Automatic left ventricle (LV) endocardial border detection is carri...
