aortic flow reversal
Retrograde blood flow in the aorta during diastole, typically indicating aortic regurgitation.
Full Definition
Aortic flow reversal refers to the backward direction of blood flow within the aorta during ventricular diastole, most commonly occurring as a result of aortic valve regurgitation. This phenomenon can be detected using Doppler ultrasound, MRI flow studies, or invasive pressure measurements. The degree and extent of flow reversal correlate with the severity of aortic regurgitation and can extend into the abdominal aorta in severe cases. Documentation of flow reversal patterns helps assess hemodynamic significance and guide therapeutic decisions.
Usage
Usage note: Specify anatomical location and timing within cardiac cycle; may be described as holodiastolic or early diastolic.
