Key result
An indicator technic permitted the estimation of backflow velocity in the descending aorta of patients with aortic insufficiency, with instantaneous back-velocities exceeding 100 cm/sec observed.
Why the study?
Can an indicator technic quantify backflow velocity in patients with aortic insufficiency?

Can an indicator technic quantify backflow velocity in patients with aortic insufficiency?
The study describes an indicator technique to quantify the time-course of backflow velocity and volume per stroke in patients with aortic insufficiency.

May aid severity assessment in aortic insufficiency; leaves open validation before clinical adoption.
A method is reported which permits the estimation of the time-course of backflow velocity in the descending aorta of patients with insufficiency of the aortic valve. Instantaneous back-velocities in excess of 100 cm./sec. have been observed. Evidence suggesting the existence of an oscillation in aortic flow during diastole in some patients is presented. An index to the "volume of backflow per stroke" is described.
