多模态影像及3D打印技术在经导管二尖瓣缘对缘修复术中的应用

Application of multimodality imaging and 3d printing technique in transcatheter mitral valve edge-to-edge repair

摘要: 多模态影像是指联合多种影像学成像技术不同模态的图像信息，多种学科优势互补，交叉验证，在疾病诊断和治疗中的综合成像模式。经导管二尖瓣缘对缘修复术已经发展成为外科高风险二尖瓣反流患者外科修复的一种替代方案。为了保证手术的安全性和成功率，经导管二尖瓣缘对缘修复术对多模态影像的依赖性也越来越强。该文主要对经胸超声心动图、经食道超声心动图、多层螺旋CT、心脏磁共振及二尖瓣3D打印模型在TEER中的应用进行了全面回顾。

Abstract: Multimodality imaging refers to a comprehensive imaging mode that combines the image information of different modes of a variety of imaging techniques, complementary advantages of various disciplines, and cross-validation in disease diagnosis and treatment. Transcatheter mitral valve edge-to-edge repair(TEER) has been developed as an alternative to surgical repair for patients with high-risk mitral regurgitation. In order to ensure the safety and success rate of surgery, TEER is more and more dependent on multimodality imaging. In this paper, the applications of transthoracic echocardiography (TTE), transesophageal echocardiography (TEE), multidetector row computed tomography (MDCT), cardiac magnetic resonance (CMR) and mitral valve 3D printing model in TEER were reviewed.
