Estimation of 3D left ventricular deformation from echocardiography
The quantitative estimation of regional cardiac deformation from 3D image sequences has important clinical implications for the assessment of viability in the heart wall. Such estimates have so far been obtained almost exclusively from Magnetic Resonance (MR) images, specifically MR tagging. In this paper we describe a methodology for estimating cardiac deformations from 3D echocardiography (3D...
متن کاملNoninvasive mapping of left ventricular electromechanical asynchrony by three-dimensional echocardiography and semi-automatic contour detection.
A system for analyzing left ventricular (LV) electromechanical asynchrony based on transesophageal 3-dimensional echocardiography (3-DE) and semi-automatic endocardial contour detection is described. Eighteen consecutive patients underwent 3-DE. Using TomTec 4DLV software, a 3-dimensional endocardial surface was reconstructed throughout the cardiac cycle. Matlab software generated color-coded p...
متن کاملEchocardiography of left ventricular masses.
The M-mode and two-dimensinal real-time echocardiographic findings in 10 patients with left ventricular masses are discussed. Two patients had left ventricular tumors and eight had left ventricular thrombi. In all cases the diagnosis was confirmed by angiography or surgery. The intracavitary and intramural left ventricular tumors were detected both by M-mode and two-dimensional echocardiography...
متن کاملDiastolic left ventricular functional indices: Comparison between gated myocardial perfusion SPECT and echocardiography
Introduction: Many patients have only diastolic dysfunction without any abnormality in systolic function. We compared cardiac diastolic parameters obtained by gated myocardial perfusion SPECT (Gated SPECT) with those evaluated by echocardiography. Methods: Forty-nine patients (aged 37-85 years, 19 males and 30 women) underwent Gated SPECT and echocardiogr...
متن کاملApical transverse motion as surrogate parameter to determine regional left ventricular function inhomogeneities: a new, integrative approach to left ventricular asynchrony assessment.
AIMS Left ventricular (LV) asynchrony assessment is mostly based on delays between regional myocardial velocity peaks. Regional function is barely considered. We propose apical transverse motion (ATM) as a new parameter integrating both temporal and functional information, which was tested in different conduction delays. METHODS AND RESULTS We examined 67 patients, 11 patients with post-infar...
