WebJul 15, 2024 · Citation, DOI, disclosures and article data. Aortic valve regurgitation, also known as aortic valve insufficiency or aortic valve incompetence, is a valvulopathy that describes leaking of the aortic valve during diastole that causes blood to flow in the reverse direction from the aorta and into the left ventricle. WebAim: Although the diastolic flow reversal of the descending aorta has been recognized in patients with aortic regurgitation, its generation without this condition is still unknown. …
WebApr 27, 2015 · Because the aortic flow reversal increases the blood spillover from the proximal descending aorta to the supra-aortic arteries, 14 it can be theoretically thought to reduce the antegrade flow (ie, diastolic runoff) toward the abdominal aorta. 12 Therefore, we hypothesized that the aortic flow reversal as exaggerated by aortosclerosis would …
