AI Article Synopsis

Article Abstract

Aims: The pressure increase per time unit (dP/dt) in aortic stenosis (AS) jet velocity is assumed to have inter-individual variability in the progressive AS stage. We sought to examine the association of aortic valve (AoV) Doppler-derived dP/dt in patients with mild to moderate AS with risk of progression to severe disease.

Methods And Results: A total of 481 patients diagnosed with mild or moderate AS [peak aortic jet velocity (Vmax) between 2 and 4 m/s] according to echocardiographic criteria were included. AoV Doppler-derived dP/dt was determined by measuring the time needed for the pressure to increase at a velocity of the AoV jet from 1 m/s to 2 m/s. During a median follow-up period of 2.7 years, 12 of 404 (3%) patients progressed from mild to severe AS and 31 of 77 (40%) patients progressed from moderate to severe AS. AoV Doppler-derived dP/dt had a good ability to predict risk of progression to severe AS (area under the curve = 0.868) and the cut-off value was 600 mmHg/s. In multivariable logistic regression, initial AoV calcium score (adjusted odds ratio [aOR], 1.79; 95% confidence interval [CI], 1.18-2.73; P = 0.006) and AoV Doppler-derived dP/dt (aOR, 1.52/100 mmHg/s higher dP/dt; 95% CI, 1.10-2.05; P = 0.012) were associated with progression to severe AS.

Conclusion: AoV Doppler-derived dP/dt above 600 mmHg/s was associated with risk of AS progression to the severe stage in patients with mild to moderate AS. This may be useful in individualized surveillance strategies for AS progression.

Background: In dogs, due to better alignment with the aortic outflow, the subcostal (SC) transducer site provides greater Doppler-derived velocities than those obtained from the left parasternal view. The feasibility of this imaging approach has never been described in equine echocardiography.

Objectives: The objective of this study was to evaluate the feasibility of the SC view in newborn foals and compare aortic two-dimensional and Doppler-derived velocity measurements with those of standard parasternal long-axis (LAX) views.

Objectives: Although the postnatal physiology of D-loop transposition of the great arteries with intact ventricular septum (D-TGA/IVS) is well established, little is known about fetal D-TGA/IVS. In the normal fetus, the pulmonary valve (PV) is larger than the aortic valve (AoV), there is exclusive right-to-left flow at the foramen ovale (FO) and ductus arteriosus (DA), and the left ventricle (LV) ejects 40% of combined ventricular output (CVO) through the aorta, primarily to the brain. In D-TGA/IVS, the LV ejects oxygen-rich blood to the pulmonary artery, theoretically leading to pulmonary vasodilation, increased branch pulmonary artery flow and reduced DA flow.
