Implication

Distal aortic pressure recordings may confound gradient interpretations; leaves open optimal measurement sites for accurate hemodynamic studies.

Structured PICO

Population

Anesthetized and unanesthetized dogs

Intervention

Recording of left ventricular and aortic pressure pulses and the pressure gradient across the aortic valve at different sites (immediately above the valve vs 1-3 cm distal)

Outcome

Systolic pressure gradients across the aortic valve and in the ascending aortasurrogate

Recording aortic pressure distal to the valve alters pressure pulse relationships due to a delay in the pulse wave and a negative mean systolic pressure gradient in the ascending aorta.
