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

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.
