WebBackground: Assessing the true severity of aortic stenosis (AS) remains a challenge, particularly when echocardiography yields discordant results. Recent European and American guidelines recommend measuring aortic valve calcium (AVC) by multidetector row computed tomography (MDCT) to improve this assessment.Aim: To define, using a … WebComputed tomography aortic valve calcium scoring for the assessment of aortic stenosis progression CT-AVC is reproducible and demonstrates larger increases over …

WebIn the aortic stenosis cohort, the indexed contrast CT calcium volume increased with stenosis severity (mild: 39 (19–64), moderate: 85 (46–187), severe: 190 (113–254) mm 3 /cm 2; figure 1A) and correlated moderately well with peak aortic jet velocity (r=0.62, p<0.001; online supplemental table 1 ). WebFeb 27, 2024 · In this trial, the sensitivity of CCTA to predict a stenosis >50% on ICA was far superior to MPI utilizing both a CCTA stenosis ≥50% (92.0% vs 54.5%, p<0.001) or ≥70% (92.6% vs 59.3%, p<0.001). The odds ratio for CAD on ICA was 12.73 (95%CI 2.43-66.55, p<0.001) for a summed stress score by MPI ≥5% (utilizing a 17-segment model).
