Imaging after revascularization

Stents Konstantin Nikolaou, Tuebingen/DE Description The number of percutaneous coronary interventions with stent placement is ever increasing, with a widening variety of implanted stent types (bare metal stents, drug-eluting stents, bioresorbable stents…). Non-invasive imaging of coronary artery stents has always been a challenge. Using Computed Tomography Angiography (CTA), visualization of the stent lumen and potential in-stent stenosis can be difficult, depending on the stent material and stent diameter, and is thus not recommended in the current guidelines. Newer CT technologies, however, might overcome these limitations. On the other hand, functional imaging of the myocardium, e.g., MRI-based imaging of myocardial perfusion, might play a significant clinical role in patients after coronary stent placement and new onset of symptoms. CABG Karl-Friedrich Kreitner, Mainz/DE Description Coronary artery bypass grafting (CABG) is still an important treatment modality especially in advanced coronary artery disease. MD-CTA is a fast and reliable non-invasive method for morphologic assessment of bypass grafts with high sensitivity and specificity. With newer CT scanner generation a remarkable reduction of radiation dose exposure has been possible while maintaining a still excellent image quality. With MRI perfusion imaging, stress-induced myocardial ischemia can be detected thus indicating the need for repeat revascularization. Based on selected cases, the participants will be demonstrated the possibilities of modern cross-sectional imaging in patients after CABG.
