Imaging of the right ventricle with 2-dimensional echocardiography (2-D echo) is hampered by trabeculation of the right ventricular (RV) endocardial surface and by limited echocardiographic resolution. Determination of RV ejection fraction (EF) is thus often an inconsistent and tedious procedure. The process of digital subtraction contrast echocardiography(More)
Three-dimensional reconstructive echocardiography provides the necessary data for a complete description of cardiac structure and function. It is implemented using an inexpensive position locating device, a sector scanner, and a general purpose computer with attached image and graphics processors. Its application to the three-dimensional reconstruction of(More)
The inter- and intraobserver variability in applying current diagnostic criteria for mitral valve prolapse as seen on two-dimensional echocardiograms is appreciable. It is therefore proposed that new methods employing computer-based pattern recognition algorithms be developed. The criteria will focus on the shape of the valve throughout systole. Shape(More)
