BACKGROUND Three-dimensional (3D) printed models have been recently introduced for diagnosis and preprocedural planning for percutaneous interventions or surgery in cardiovascular disease. CASE REPORT We treated a 71-year-old woman with angina. Although we performed coronary angiography, we could not engage the catheters for the left coronary artery (LCA). Then, we withdrew the catheter and examined her anatomy using coronary computed tomographic angiography (CCTA). The CCTA revealed that the LCA originated from the noncoronary cusp (NCC). Because anomalous LCA originating from the NCC is a rare congenital anomaly, percutaneous coronary intervention was considered difficult. We decided to use a 3D-printed model, which enabled us to clearly see the anatomy and simulation before the actual procedure, which went smoothly according to the preprocedural planning using the 3D printed model. 3D printed modeling is feasible for use in reproducing coronary artery anatomy and enhancing understanding of coronary abnormalities. CONCLUSIONS Use of 3D-printed models is a useful new option that can help visualize the anatomy and perform preprocedural planning for complex cases.
背景 三维（3D）打印模型最近已被引入心血管疾病的经皮介入或手术的诊断和术前规划中。
病例报告 我们治疗了一位 71 岁的心绞痛女性患者。尽管我们进行了冠状动脉造影，但无法将导管插入到左冠状动脉（LCA）。然后，我们撤回导管并用冠状动脉计算机断层扫描血管造影（CCTA）检查她的解剖结构。CCTA 显示 LCA 起源于非冠状动脉瓣（NCC）。由于起源于 NCC 的异常 LCA 是一种罕见的先天性异常，因此经皮冠状动脉介入治疗被认为很困难。我们决定使用 3D 打印模型，这使我们能够在实际手术前清晰地看到解剖结构和模拟，根据使用 3D 打印模型进行的术前规划，手术过程非常顺利。3D 打印建模可用于再现冠状动脉解剖结构，增强对冠状动脉异常的理解。
结论 使用 3D 打印模型是一种有用的新选择，可以帮助可视化复杂病例的解剖结构并进行术前规划。
