Abstract

Purpose: The aim of this study was to evaluate the feasibility and accuracy of 2-dimensional (2D) and 3-dimensional (3D) transthoracic echocardiography (2DTTE, 3DTTE) versus multidetector computed tomography (MDCT) in patients with ascending aortic (AA) dilation. Materials and Methods: Fifty consecutive patients with AA dilation were evaluated by 2DTTE, X-plane (XP) 3DTTE, and MDCT. Aorta diameters were measured at aortic annulus, aortic root (SIN), sinotubular junction, AA, aortic arch before the prebrachiocephalic artery (PRE), and before left subclavian artery (INTRA). Leading edge-to-leading edge (L-L) and inner-to-inner (I-I) measurements were compared with MDCT data. Results: Feasibility, quality of imaging, and accuracy was high with all echocardiographic methods. Specifically for MDCT maximum SIN diameter, the best correlation and agreement was obtained using XP maximum diameter at 3DTTE (MDCT: 44.8±7.4 mm vs. XP: 44.4±7.4 mm; r=0.975; bias=-0.4 mm). The same was true for AA maximum diameter at MDCT (MDCT: 46.6±8.1 mm vs. XP: 47.5±8.1 mm; r=0.991; bias=0.1 mm). For aortic arch the best correlation and agreement with MDCT were as follows: 2DTTE L-L diameter for arch PRE (MDCT: 37.9±5.3 mm vs. TTE: 36.6±4.5 mm; r=0.927; bias=-0.9 mm) and MDCT minimum diameter with XP minimum diameter for arch INTRA (MDCT: 28.2±5.0 mm vs. TTE 28.8±4.7 mm; r=0.939; bias=-0.3 mm). Conclusion: In patients with aortic dilatation or aneurysm, new techniques (mainly 2D-3D probes allowing XP views) facilitate accuracy of aortic measurements at different sites of the vessel and allow standardization of analysis to better compare with MDCT.
