目的：该前瞻性研究的目的是评估最近开发的3D系统（CardiOp-B; Paieon Medical Ltd.，方法和结果：在安排心脏导管插入的患者中，使用QCA和3D系统获得CAS的最小管腔直径（MLD）和直径衍生的狭窄百分比（DPS）（>50%）。为了估计狭窄长度，将未充盈的球囊插入狭窄中，使用两种方法测量球囊标记之间的距离，然后与标记之间的已知距离进行比较。分析了61例患者的79处病变。MLD测量结果显示QCA和3D之间具有良好的一致性，平均差异为0.08 +/- 0.035 mm。3D的参考直径为2.61 +/- 0.67 mm，QCA为2.42 +/- 0.61 mm，狭窄百分比范围分别为54.79 +/- 9.20%和58.75 +/- 8.15%。平均真实球囊长度为12.8 mm +/- 3.8 mm。3D系统测定的球囊长度分别为13.0 +/- 4.0 mm和11.3 +/- 3.8 mm by QCA，either.Conclusions：使用新型3D系统评价CAS是可行的，并显示与经验证的QCA测量结果等效的结果。与QCA相比，3D系统的长度测量似乎更准确。因此，该3D系统可用于指导介入心脏病学的决策。
Aims: The aim of this prospective study was to evaluate the feasibility and accuracy of a recently developed 3D system (CardiOp-B; Paieon Medical Ltd., Israel) as compared to a validated quantitative coronary angiography (QCA) system (Siemens Quantcor, Siemens Medical Solutions).Methods and results: In patients scheduled for heart catheterisation, minimal lumen diameter (MLD) and diameter-derived percent stenosis (DPS) were obtained for CAS (>50%) using both QCA and the 3D-system. To estimate stenosis length, a non-inflated balloon was inserted into the stenosis and the distance between balloon markers was measured using both methods and then compared to the known distance between the markers. In 61 patients 79 lesions were analysed. MLD measurements showed a good agreement between QCA and 3D with a mean difference of 0.08 +/- 0.035 mm. Reference diameter was 2.61 +/- 0.67 for 3D and 2.42 +/- 0.61 mm for QCA and 54.79 +/- 9.20% vs. 58.75 +/- 8.15% for the %-stenosis range, respectively. The mean true balloon length was 12.8 mm +/- 3.8 mm. Lengths determined by the 3D system were 13.0 +/- 4.0 mm and 11.3 +/- 3.8 mm by QCA, respectively.Conclusions: Evaluation of CAS using the novel 3D system was feasible and showed equivalent results to validated QCA measurements. Length measurements seemed to be more accurate by the 3D system as compared to QCA. Therefore, this 3D-system can be used to guide decisions in interventional cardiology.
