经股动脉入路是TAVI中的首选瓣膜输送途径，因为经股动脉入路的侵入性较小，据报告并发症较少。1，2然而，包括入路狭窄、主动脉粗糙、壁内血肿和迂曲主动脉在内的一些情况有时会禁止经股动脉入路的应用。在这种情况下，基于患者特定3D模型的术前模拟可有效确定治疗策略。虽然3D打印器官模型的有效性已被零星报道，但这是第一例涉及基于患者数据构建3D主动脉模型并在推进瓣膜时测量施加到主动脉壁的压力的病例。预计进一步的研究将阐明使用患者特定的3D模型是否有助于决策并减少TAVI相关并发症。
Transfemoral approach is the preferred valve delivery route in TAVI because transfemoral approach is less invasive and reported to have fewer complications. 1, 2 However, several conditions, including a narrow access route, a shaggy aorta, an intramural hematoma, and a tortuous aorta, occasionally prohibit the application of the transfemoral approach. The preprocedural simulation based on a patient-specific 3D model was effective to determine the treatment strategy in this case. Although the efficacy of 3D printed organ models has been sporadically reported, 3 this is the first case involving the construction of a 3D aortic model on the basis of patient’s data and measuring the pressure applied to the aortic wall while advancing the valve. Further studies are expected to clarify whether the use of patient-specific 3D models facilitate decision making and reduce TAVI-related complications.
