Dynamic three dimensional evaluation of intracardiac flow

Abstract

Three-dimensional color Doppler is a new technique that provides three dimensional images of intracardiac flow jets. Despite the different measurement methods available, noninvasive quantification of valve regulation is still controversial in some cases. It is also sometimes difficult to appreciate the spatial extension of the jet. Visualisation of regurgitant flows in three dimensions shows its complex shape, origin, direction and spatial distribution, and correlates accurately with regurgitant volume and regurgitant fraction by different methods (angiography, two-dimensional Doppler). Unnoticed its in the two-dimensional image have been detected with the three-dimensional image and additional qualitative information to the two dimensional image has been provided by this new technique in a high percentage of patients.
