Journal ArticleDOI
Characterization and Quantification of Vortex Flow in the Human Left Ventricle by Contrast Echocardiography Using Vector Particle Image Velocimetry
Geu Ru Hong,Gianni Pedrizzetti,Giovanni Tonti,Peng Li,Zhao Wei,Jin Kyung Kim,Abinav Baweja,Shizhen Liu,Namsik Chung,Helene Houle,Jagat Narula,Mani A. Vannan +11 more
TL;DR: It was feasible to quantify LV vorticity arrangement by CE using particle image velocimetry in normal subjects and those with LV systolic dysfunction, and the vortivity imaging by CE may serve as a novel approach to depict vortex, the principal quantity to assess the flow structure.
Journal ArticleDOI
Emerging trends in CV flow visualization
Partho P. Sengupta,Gianni Pedrizzetti,Philip J. Kilner,Arash Kheradvar,Tino Ebbers,Giovanni Tonti,Alan G. Fraser,Jagat Narula +7 more
TL;DR: This document provides a descriptive outline of the relevant concepts in cardiac fluid mechanics, including the emergence of rotation in flow and the variables that delineate vortical structures, and elaborate on the main methods developed to image and visualize multidirectional cardiovascular flow.
Journal ArticleDOI
The vortex--an early predictor of cardiovascular outcome?
TL;DR: It is postulate that maladaptive intracardiac vortex dynamics might modulate the progressive remodelling of the left ventricle towards heart failure and presents a new paradigm in cardiac function analysis, with the potential for sensitive risk identification of cardiac abnormalities.
Journal ArticleDOI
Echocardiographic particle image velocimetry: a novel technique for quantification of left ventricular blood vorticity pattern.
Arash Kheradvar,Helene Houle,Gianni Pedrizzetti,Giovanni Tonti,Todd Belcik,Muhammad Ashraf,Jonathan R. Lindner,Morteza Gharib,David J. Sahn +8 more
TL;DR: The E-PIV technique appears to be capable of evaluating the major flow features in the ventricles, however, the bounded spatial resolution of ultrasound imaging limits the small-scale features of ventricular flow to be revealed.
Journal ArticleDOI
Magnetic Resonance Derived Myocardial Strain Assessment Using Feature Tracking
Kan N Hor,Rolf Baumann,Gianni Pedrizzetti,Giovanni Tonti,William M. Gottliebson,Michael D. Taylor,D. Woodrow Benson,Wojciech Mazur +7 more
TL;DR: This new method offers a robust and time saving procedure to quantify myocardial tissue and blood with displacement, velocity and deformation parameters on regular sequences of CMR imaging and can be implemented in clinical practice.
