Characteristics and Pattern of Calcified Nodule and/or Nodular Calcification Detected by Intravascular Ultrasound on the Device-Oriented Composite Endpoint (DoCE) in Patients with Heavily Calcified Lesions Who Underwent Rotational Atherectomy-Assisted Percutaneous Coronary Intervention

Figure 3

Central illustration. Drawing and IVUS results pre- and post-stent implantation, comparison of primary outcome according to calcific plaque and characteristic and pattern of calcified nodule/nodular calcification are presented. (a) Drawing and IVUS imaging showed pre- and post-stent for concentric calcification with calcified nodule/nodular calcification. (b) Drawing and IVUS imaging showed pre- and post-stent for an eccentric calcified nodule/nodular calcification. (c) A forest plot showing the adjusted hazard ratios and 95% confidence intervals for the primary outcome. (d) Kaplan-Meier survival analysis for the primary outcome after RA-assisted intravascular ultrasound (IVUS)-guided PCI compared among different subtypes of calcific plaque and calcified nodule/nodular calcification characteristics. IVUS: intravascular ultrasound; DoCE: device-oriented composite endpoint; RA: rotational atherectomy; PCI: percutaneous coronary intervention; CN: calcified nodule; and NC: nodular calcification.
