ABSTRACT
<p><b>OBJECTIVE</b>To compare the efficacy of three-dimensional (3D) and two-dimensional (2D) quantitative coronary X-ray angiography (QCA) and visual estimation in the assessment of target vessels.</p><p><b>METHODS</b>The radiographic data of 60 patients (65 vessel segments) receiving coronary angiography and interventional stent placement were retrospectively analyzed. The area stenosis, diameter stenosis, lesion length, and reference diameter assessed by Medis 3D QCA, Siemens 2D QCA and visual estimation were compared.</p><p><b>RESULTS</b>Three-dimensional reconstruction was successfully performed for 65 vessel segments, and 3 target vessel were excluded due to the lack of a second angiographic view for 3D reconstruction. There were significant differences in the assessments of the area stenosis [(73.87 ∓ 8.98)% vs (79.10 ∓ 8.06)% vs (83.53 ∓ 8.19)%, P<0.001], lesion length (28.95 ∓ 17.31 mm vs 26.20 ∓ 16.04 mm vs 27.21 ∓ 16.58 mm, P<0.001), reference diameter (28.95 ∓ 17.31 mm vs 26.2 ∓ 16.04 mm vs 27.21∓16.58 mm, P<0.001) by 3D QCA, 2D QCA and visual estimation; the diameter stenosis assessed by 3D [(54.21 ∓ 9.48)%] and 2D QCA [(57.84 ∓ 10.17)%] also differed significantly (P=0.016).</p><p><b>CONCLUSION</b>3D QCA allows successful three-dimensional reconstruction of the target vessel and restores the actual dimensions of the vessel for a more accurate assessment of coronary artery disease than 2D QCA and visual estimation.</p>
