Imaging Modality Supporting New Device Therapy

Device has been exclusively used for the endovascular therapy as an extension of catheter therapy in the cardiovascular medicine. Most recently, it is drawn considerable attention to use new devices as a therapy of structural heart diseases (SHDs). The newly developed device therapy has gained popularity at least partially through the marked improvement in catheterization technique and also in imaging modality. In this symposium we will focus on recent advance in imaging modality supporting new device therapy. Bioresorbable scaffolds have potential advantages over current metallic DES technology as a therapy of coronary artery diseases. Values of the bioresorbable scaffolds may be optimized with further improvement in current imaging modality such as IVUS. Stent grafts have been used to treat aortic and peripheral artery diseases, and we expect further improvement in long-term outcome or results. Device therapy has considerably grown as a new non or minimal invasive treatment of SHDs. Many patients with high risk aortic stenosis are now treated with transcatheter aortic valve replacement（TAVR）in Japan. Mitral regurgitation will be treated with MitraClip even in Japan in near future. Many patients with atrial septal defect have been treated with Amplatzer Septal Occluder. Successful new device therapy may be achieved only with adequate use of imaging modalities such as CT, MR, transthoracic and transesophageal echocardiography perioperatively. In this symposium, we discuss the role and problems of imaging modality supporting new device therapy in order to get insight into the future.
