WebThe presence of a low transvalvular pressure gradient (<40 mm Hg) in conjunction with a small aortic valve area (AVA ≤1 cm2) is a challenging situation as it raises uncertainty about the actual severity of aortic stenosis (AS) and therefore about the indication of aortic valve replacement (AVR) if the patient is symptomatic. This low-gradient ‘severe’ (small AVA) … WebIn a descending thoracic aorta long-axis view, the PW sample volume is placed distally toward the abdominal aorta.

WebHolodiastolic flow reversal (HDFR) in the descending aorta (DAO) is considered a sign of ≥ moderate aortic insufficiency (AI) in both adults and children. In congenital heart disease, our experience suggests this measure can overestimate AI when compared to cardiac magnetic resonance imaging (cMRI).
