Figure 8. Staged PCI for a severely calcified LAD-diagonal bifurcation. (A) Angiographic views showing diseased LAD and diagonal vessels; (B) OCT of the LAD showing a non-eruptive nodule. The diagonal was pre-dilated to facilitate OCT; (C) OCT of the diagonal showing non-eruptive nodules at the ostium; (D) RA of the diagonal with 1.5 mm and 1.75 mm burrs. The diagonal was then post-dilated with a 2.5 mm NC balloon, followed by deployment of a 2.5 × 18 mm DES; (E) DK Crush was performed; (F) Final OCT post-PCI. PCI: percutaneous coronary intervention; DES: drug-eluting stent; OCT: optical coherence tomography; RA: rotational atherectomy; NC:
