The patient was a 67-year-old man, with a history that included hypertension, diabetes, and dyslipidemia. He presented with a non–ST-segment elevation lateral myocardial infarction. The Figure 1A shows a severe bifurcation lesion (1,0,0) (arrow) in the circumflex artery, which was resolved by implantation of a specific stent for bifurcations (3.5×14mm Axxess) (Figure 1B, box), with a good angiographic result (Figure 1B). Optical coherence tomography using 3-dimensional reconstruction confirmed the correct apposition of the stent in distal terms and the proper covering of the ostium of both branches, leaving the carina free of struts (Figure 2). Using the OPTIS Metallic Stent Optimization software package, we processed the images (Figure 2, Figure 3A, Figure 3B, and Video of the supplementary material), in which it is possible to see a discernible poor apposition at the middle level and very poor apposition at the proximal level. The struts colored in yellow represent slightly poor apposition, whereas those in red reflect considerably poor apposition (> 300μm). Given these findings, we performed postdilatation with an unadaptable balloon, and the angiographic results were excellent, as shown by optical coherence tomography. The results after implantation were evaluated using intracoronary imaging techniques, especially when the lesions involved the bifurcation. They were very useful despite the good angiographic results. Reconstruction using the Metallic Stent Optimization system shows, in a novel, rapid and highly illustrative way, the results after the implantation.
