A 57-year-old male patient with a history of a medically managed inferior myocardial infarction 10 years previously underwent invasive catheter angiography. Coronary angiography revealed a patent right coronary artery with TIMI 3 flow and multiple linear filling defects (Figure 1A). Intracoronary imaging was performed with a “Lunawave®” optical frequency domain imaging catheter (OFDI) (Terumo Corp., Tokyo, Japan). This revealed that the right coronary artery had recanalised with the presence of a multiply septated lumen (Figure 1B). The OFDI images underwent three-dimensional reconstruction, allowing visualisation of multiple large spiralling channels (Figure 1C). The development of neovascular channels in chronically occluded coronary arteries has ...
