Patients with tetralogy of Fallot, pulmonary atresia, and multiple aortopulmonary collateral arteries (Tet PA MAPCAs) have a wide spectrum of anatomy and disease severity. Management of these patients can be challenging and often require multiple high-risk surgical and interventional catheterization procedures. These interventions are made challenging by complex anatomy that require the proceduralist to mentally reconstruct three-dimensional anatomic relationships from two-dimensional images. Three-dimensional (3D) printing is an emerging medical technology that provides added benefits in the management of patients with Tet PA MAPCAs. When used in combination with current diagnostic modalities and procedures, 3D printing provides a precise approach to the management of these challenging, high-risk patients. Specifically, 3D printing enables detailed surgical and interventional planning prior to the procedure, which may improve procedural outcomes, decrease complications, and reduce procedure-related radiation dose and contrast load.
患有法洛四联症、肺动脉闭锁和多发性主肺动脉侧支动脉（法洛四联症合并肺动脉闭锁及多发性主肺动脉侧支动脉）的患者具有广泛的解剖结构和疾病严重程度。这些患者的治疗具有挑战性，通常需要多次高风险的外科手术和介入导管操作。复杂的解剖结构使这些干预措施具有挑战性，这要求术者从二维图像中在脑海中重建三维解剖关系。三维（3D）打印是一种新兴的医疗技术，在法洛四联症合并肺动脉闭锁及多发性主肺动脉侧支动脉患者的治疗中具有额外的优势。当与当前的诊断方式和操作相结合使用时，3D打印为这些具有挑战性的高风险患者的治疗提供了一种精确的方法。具体而言，3D打印能够在手术前进行详细的手术和介入规划，这可能会改善手术结果、减少并发症，并降低与手术相关的辐射剂量和造影剂负荷。
