774-2 Automated On-Line Assessment of Spatial and Temporal Abnormalities in Regional Left Ventricular Wall Motion Using Color-Encoded Acoustic Quantification of Radiofrequency Echocardiographic Signals: Description of the Method and Early Clinical Application

Autor: Oi-Ling Cao, Joanne Zachistal, Steven L. Schwartz, Natesa G. Pandian, Janet Simonetti, Marjory Caldeira, Mani A. Vannan

Publikováno v: Journal of the American College of Cardiology. 25(2):288A-289A

Until now assessment of regional wall motion abnormalities has relied on either a visual wall motion scoring (WMS) system or tedious off-line border analysis. We explored the potential of a new AQ approach for defining regional WMA. This approach pro

946-109 Measurement of Right Ventricular Mass of Small and Large Hearts by Quantitative Volume-Rendered Three-dimensional Echocardiography Without the Use of Geometric Assumptions: Experimental Validation

Autor: Oi-Ling Cao, Natesa G. Pandian, Alain Delabays, Lissa Sugeng

Publikováno v: Journal of the American College of Cardiology. 25:175A

Despite a need for a method to measure right ventricular (RV) mass, the unusual geometry of the RV has made application of common imaging approaches unreliable. Recent developments in volume-rendered threedimensional echocardiography (3DE) suggest th

1002-86 Direct Quantitation of Atrial Septal Defect Size by Volume-Rendered Three-Dimensional Echocardiography: In Vitro Validation Studies

Autor: Alain Delabays, Natesa G. Pandian, Oi-Ling Cao, Gerald R. Marx, Michael Vogel, Lissa Sugeng, Giuseppina Magni, Achi Ludomirski

Publikováno v: Journal of the American College of Cardiology. 25:350A

The ability of volume-rendered three-dimensional echocardiography (3DE) in displaying atrial septal defects (ASD) in a dynamic mode has been demonstrated; however the quantitative accuracy of 3DE in sizing the defect is not known. In this study, we e

1002-85 Utility of Unique Projections in Dynamic Transthoracic Three-Dimensional Echocardiography in the Pre- and Post-Operative Delineation of Lesions Associated with Tetralogy of Fallot in Neonates and Infants

Autor: Michael Vogel, Achi Ludomirski, Lissa Sugeng, Natesa Pandian, Alain Delabays, Barbara Romero, Oi-Ling Cao, David Fulton, Gerald Marx

Publikováno v: Journal of the American College of Cardiology. (2):349A-350A

Management of tetralogy of Fallot (TOF) is influenced by the size and position of the ventricular septal defects (VSD) and the size and magnitude of infundibular, and pulmonary annular and arterial obwtruction. Three dimensional (3D) visualization ma

939-80 Quantitative Three-Dimensional Echocardiographic Estimation of Ischemic and Non-ischemic Myocardial Mass and its Relation to the Mass of Dysfunctional LV Myocardium During Coronary Occlusion

Autor: Steven L. Schwartz, Giuseppina Magni, Alain Delabays, Oi-Ling Cao, Natesa G. Pandian, Lissa Sugeng

Publikováno v: Journal of the American College of Cardiology. (2):163A

While measurement of non-perfused LV mass is possible in autopsied hearts with pre-injected radionuclide agents, in vivo measurement of the mass of ischemic (ISC) myocardial (M) regions has not been feasible. 2D echo with contrast depicts ISC regions
