Intracardiac Flow Analysis: Techniques and Potential Clinical Applications

Analysis of intracardiac flows has gained increasing interest in the last years. This analysis has become possible due to the development of technologies for noninvasive cardiovascular imaging, which allow visualization and quantitation of intracardiac flow dynamics. Several studies have shown that abnormalities in cardiac function are related to changes in intracardiac vortical flows. Thus, analysis of cardiac vortex has been used for better understanding of the pathophysiology in many heart diseases and to test initial clinical hypotheses. The aims of this review are to introduce the reader to the topic of intracardiac flow dynamics, to briefly describe current cardiac imaging techniques for analysis of the intracardiac vortex, and to indicate potential clinical applications of a vortex-based approach to the study of cardiac function.
