Spontaneous coronary artery dissection (SCAD) has a prevalence between 0.2%-4% of all acute coronary syndromes. Multivessel SCAD is unusual. Coronary revascularization remains appropriate for unstable patients or with compromised coronary blood flow. Additionally, IVUS probe advancement and its retrieval could precipitate a dramatic progression of SCAD both distally and proximally to its original site.
