Reduction of Lipid-Core Burden Index in Nonculprit Lesions at Follow-Up after ST-Elevation Myocardial Infarction: A Randomized Study of Bioresorbable Vascular Scaffold versus Optimal Medical Therapy
Figure 7
Example of persistently high maxLCBI4 mm after BVS implantation. (a) Baseline angiography showing a moderate lesion in the mid-left anterior descending coronary artery. (b) Baseline NIRS showing a calcified NC-LRP. (c) Angiography of the BVS implantation. (d) Follow-up NIRS showing a persistently high maxLCBI4 mm at the site of the original NC-LRP. (e) IVUS demonstrating good expansion of the scaffold in the calcified plaque. (f) OCT showing a good result of the BVS at follow-up with an appropriate expansion, apposition, and endothelialization. BVS = bioresorbable vascular scaffold; NIRS = near-infrared spectroscopy; NC-LRP = nonculprit lipid-rich plaque; IVUS = intravascular ultrasound; OCT = optical coherence tomography; and maxLCBI4 mm = maximum lipid-core burden index in a 4 mm length of the artery.
