  Fig. 1. A: Angiographic assessment demonstrating a diffuse tubular stenosis from segment 2 of the RCA; B and C: OCT image demonstrating false lumen with intramural haematoma (red point) and showing residual blood artefact (plus sign) (yellow border: external elastic membrane; red border: luminal contour; *: wire artefact); D: final angiographic assessment, at time of index procedure, demonstrating minor balloon-related dissection in the mid-vessel (arrow); E: OCT cross section in the mid-RCA showing medial layer thickness, with folding of the luminal intimal contour (arrow head); F: qualitative analysis of medial area (external elastic membrane (yellow border) – Internal Elastic Membrane (white border)) did not change when comparing the vessel with normal medial layer; G: improved intraluminal calibre with postero-lateral branch re-canalisation (arrow) on repeated angiography; H and I: OCT image showing a relatively normal vessel anatomy in the proximal RCA and the medial area of 1.53 mm2; Abbreviation: RCA = right coronary artery; OCT = optical coherence tomography.
