Implication

Accurately measures aortic velocity in animal models; leaves open human translation and clinical use pending further validation.

Structured PICO

P
Population
Flow model (small piston pump) and living animal aorta
I
Intervention
Catheter tip method for measurement of instantaneous aortic blood velocity using a specially designed double lumen catheter attached to a differential pressure transducer
C
Comparator
Known sinusoidal fluid velocity (in flow model) and velocity curves from literature (in living animal)
O
Outcome
Accuracy of computed instantaneous aortic blood velocity compared to known values or literaturesurrogate

A novel catheter tip method using a double lumen catheter and differential pressure transducer can accurately measure instantaneous aortic blood velocity in pulsatile flow.

Limitations

  • The method is applicable only to pulsatile flow.
