An 80-year-old post–coronary artery bypass graft (CABG) patient had an acute coronary syndrome with non–ST-segment elevation myocardial infarction (ACS-NSTE) with saphenous vein graft (SVG)–obtuse marginal stenosis. High-definition intravascular ultrasound revealed an underexpanded SVG stent with a hyperechoic structure. Optical coherence tomography confirmed surgical clip causing compression, resolved by post-dilation. This case underscores ACS-NSTE complexity post-CABG and the critical role of coronary imaging in optimizing interventions by addressing surgical clip–induced compression.
PET probes targeting fibroblasts are frequently used for varying applications in oncology. In recent years, the clinical spectrum has been expanded towards cardiovascular medicine, e.g., after myocardial infarction, in aortic stenosis or as a non-invasive read-out of atherosclerosis. We herein provide a brief overview of the current status of this PET radiotracer in the context of cardiovascular disease, including translational and clinical evidence. In addition, we will also briefly discuss future applications, e.g., the use of fibroblast-targeting PET to investigate bilateral organ function along the cardiorenal axis.
