Background: Echocardiography is a standard imaging technique for the assessment of heart valve disease. The good spatial and temporal resolution is the basis for different methods which provide information about the severity of such defects. Dynamic colour visualisation and volumetric measurements of regurgitant jets are a new evaluating tool for the assessment of heart valve insufficiencies. Methods: The regurgitant jet volume of 58 patients was evaluated on an external workstation after segmentation of the left atrium and compared to regurgitant volume; the correlation was good. This result is valid for central jets as well as for eccentric jets. Conclusions: Measurement of regurgitant jet volume is a method which considers the three-dimensional shape of the examined volume. Real-time visualisation techniques which support the interactive clipping of morphological structures provide dynamic visualisation of intracardiac flow during the heart cycle. Dynamic colour visualisation of jets together with myocardial structures allows the assignment of intracardiac flow to morphological structures.
