Three-dimensional echocardiography: Techniques and applications
The American Journal of Cardiology, 1992Current echocardiographic devices provide only 2-dimensional views of the heart. To appreciate 3-dimensional structural relations, therefore, requires mental reconstruction of 2-dimensional views by an experienced observer. Our ability to answer new questions about the heart could be increased if 2-dimensional images could be combined to display 3 ...

Three‐Dimensional Echocardiography of the Atrial Septum
Echocardiography, 2001This article details the important contribution of three‐dimensional echocardiography for catheterization device closure of secundum atrial septal defects. Aspects presented include three‐dimensional echocardiographic application in preselection of patients and in selection of the type and size of the atrial septal occluder devices.

Three‐Dimensional Echocardiography of Intracardiac Masses
Echocardiography, 2004We describe two cases in which three‐dimensional echocardiography provided unique anatomical data. This information enhanced the diagnostic power of two‐dimensional echocardiography by improving confidence in interpretation and by providing distinctive spatial insights.

Three-Dimensional Echocardiography in Clinical Practice
2010The heart has a complex anatomy and it is in constant motion. Conventional two-dimensional (2D) echocardiography can only provide partial information about the spatial and temporal relationship of cardiac structures during the cardiac cycle (Fig. 4.1). Furthermore, conventional 2D echocardiography requires a difficult mental process by the operator to ...

Sparse Registration for Three-Dimensional Stress Echocardiography
IEEE Transactions on Medical Imaging, 2008Three-dimensional (3-D) stress echocardiography is a novel technique for diagnosing cardiac dysfunction. It involves evaluating wall motion of the left ventricle, by visually analyzing ultrasound images obtained in rest and in different stages of stress. Since the acquisitions are performed minutes apart, variabilities may exist in the visualized cross-

Three‐Dimensional Transesophageal Echocardiography of Aortic Atherosclerosis
Echocardiography, 2012Mini‐AbstractWe present a 75‐year‐old woman with symptomatic severe aortic stenosis who underwent transesophageal echocardiography (TOE) as part of the routine examinations before scheduling transcatheter aortic valve implantation. The examination identified, in addition to severe calcific aortic stenosis, intimal thickening of the ascending aorta ...

Perioperative Echocardiography: Two-Dimensional and Three-Dimensional Applications
Anesthesiology Clinics, 2008Perioperative echocardiography is an essential skill for today's cardiac anesthesiologist and a driving force for innovation and accomplishment for the future of the subspecialty. Real-time three-dimensional transesophageal echocardiography (RT3-D TEE) will dominate the future practice of perioperative echocardiography, but transthoracic ...

Three-dimensional echocardiography.
American journal of cardiac imaging, 1993Lack of spatial registration of imaging transducers is a major technical limitation of two-dimensional (2-D) echocardiography. Volume scanning of the heart, or three-dimensional (3-D) echocardiography, is achieved by using a 3-D spatial registration device with a conventional 2-D scanner, or by using a high speed, phased-array real-time scanner. Three-

Three‐Dimensional Echocardiography in Congenital Heart Disease
Echocardiography, 2008Complex intracardiac anatomy and spatial relationships are inherent to congenital heart defects (CHDs). Recognition of the limitations of two‐dimensional echocardiography has stimulated clinical interest in three‐dimensional imaging. The current review examines contemporary studies in the following areas where three‐dimensional echocardiography has ...
