Cardiac fluid dynamics meets deformation imaging

Cardiovasc Ultrasound. 2018 Feb 20;16(1):4. doi: 10.1186/s12947-018-0122-2.

Abstract

Cardiac function is about creating and sustaining blood in motion. This is achieved through a proper sequence of myocardial deformation whose final goal is that of creating flow. Deformation imaging provided valuable contributions to understanding cardiac mechanics; more recently, several studies evidenced the existence of an intimate relationship between cardiac function and intra-ventricular fluid dynamics. This paper summarizes the recent advances in cardiac flow evaluations, highlighting its relationship with heart wall mechanics assessed through the newest techniques of deformation imaging and finally providing an opinion of the most promising clinical perspectives of this emerging field. It will be shown how fluid dynamics can integrate volumetric and deformation assessments to provide a further level of knowledge of cardiac mechanics.

Keywords: Cardiac fluid dynamics; Deformation imaging; Hemodynamic forces; Intraventricular pressure gradient; Speckle tracking.
