Nevertheless, the combination of PCI with a detailed description of lesion appearance using virtual histology-intravascular ultrasound (VH-IVUS) has never been reported. In this study, we present a case of acute myocardial infarction that was successfully treated with intravascular ultrasound (IVUS)-guided PCI for focal stenosis at the anastomotic site, and the plaque composition was studied in detail.<\/jats:p><\/jats:sec><jats:sec><jats:title>Case Presentation<\/jats:title><jats:p>A 35-year-old Korean male with Beh\u00e7et's disease was diagnosed with acute myocardial infarction. He had previously undergone three cardiothoracic surgeries including two aortic replacements, followed by modified Bentall operation with a Cabrol-type aortocoronary anastomosis. Coronary angiogram (CAG) showed focal critical stenosis at the anastomosis site between the conduit and the LMCA, and VH-IVUS showed fibrotic plaque with mainly fibrous tissue but without a confluent necrotic core. PCI was performed using a drug-eluting stent (4.5 \u00d7 12 mm, Synergy<jats:sup>TM<\/jats:sup>, Boston Scientific, Marlborough, MA, USA). Since a repeat CAG and IVUS post-surgery showed an under-expanded stent strut, post-dilation ballooning was additionally performed. Subsequently, the repeat IVUS revealed wellapposed and optimized deployment of the drug-eluting stent with full lesion coverage. Final CAG showed optimal angiographic results. After successful PCI, the patient's anginal symptoms improved dramatically, and he was successfully discharged from our hospital.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study presents an IVUS-guided PCI case for an anastomotic site between the conduit and the LMCA. It is the first to investigate the characteristics of this lesion through VH-IVUS, which demonstrated the presence of fibrous plaques at the anastomotic site. IVUS radiofrequency data allow for a detailed assessment of plaque composition and provide new insights into the histopathological nature of stenotic lesions at the anastomotic site, especially in patients with chronic inflammatory diseases like Beh\u00e7et's disease.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fcvm.2022.778815","type":"journal-article","created":{"date-parts":[[2022,3,2]],"date-time":"2022-03-02T05:12:55Z","timestamp":1646197975000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Case
