Aim: The aim of this prospective study was, to quantifies parameters of the retrograde flow (volume, flow rate) using magnetic resonance phase shift velocity and to study there relationships with aortic stiffness parameters calculated using both MRI and tonometry and waves reflections parameters.
Materials: Eighty healthy subjects without history of cardiac disease were studied (50 men and 30 women. The median age of the subjects was 42 years, ranging from 13 to 79
Results: The mean value of the retrograde volume mean was 13.2 ml (range from 2.2 to 46 ml), or expressed as a percentage of antegrade flow, it was 2.1% (range from 0.31% to 9.5%). All parameters of the retrograde flow were correlated significativly with age in univariate analysis.
The rate of the pic of retrograde flow rate to pic of the anterograde flow rate was more closely correlated to age (r=0.753, PS) compared to CF PWV (r=0.8008, PS). All parameters of the retrograde flow correlates closely to the parameters of waves reflectin calculated (Ti and Ai)
Conclusion: The retrograde flow appear to be a novel parameter of aortic stiffness witch correlates significativly with age and parameters of aortic stiffness and waves reflection.
