Abstract

We retrospectively analysed 77 consecutive patients who underwent calciumscoring and angiographic cardiac DSCT The long and shortaxis dimensions axis areas of the aortic annulus sinotubular junction and ascending aorta at the level of the pulmonary trunk in diastole and systole were measured Average dimensions and relative areal changes between diastole and systole RA of aortic annulus sinotubular junction and ascending aorta were comparedSystolic and diastolic long and shortaxis dimensions of the aortic annulus in patients with CAC n = 44 demonstrated statistically significant differences 2700 ± 284 mm vs 2804 ± 262 mm P  0001 2178 ± 255 mm vs 2088 ± 231 mm P  0001 while differences in average diameters and areas of the aortic annulus were nonsignificant P  0586 Systolic and diastolic axial areas of the sinotubular junction in patients with CAC demonstrated significant differences 721 ± 180 cm2 vs 692 ± 175 cm2 P  0001 The RA of the ascending aorta in patients with severe CAC CAC score 400 n = 15 was significantly reduced compared to patients with minimaltomoderate CAC CAC score 400 n = 29 477 ± 288 vs 751 ± 381 P = 0014In comparison with patients without CAC the long and shortaxis dimensions of the aortic annulus and areas of the sinotubular junction show significant differences during the cardiac cycle in patients with CAC The presence of severe CAC significantly influences the flexibility of the wall of the ascending aortaNo funding was received Ralf W Bauer and J Matthias Kerl are on the speaker’s bureau of Siemens Healthcare Computed Tomography division All other authors have no conflicts of interest Furthermore all data in this study was controlled by authors with no conflicts of interest
