Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Patients aged ≥ 18 years old and;
* Patients with clinical indication for stent implantation and;
* Patients with OCT evaluation that shows the presence of calcified tissue underlying the lumen surface, fulfilling the definition of superficial calcium (The distance from the abluminal point of the calcium to the luminal surface is less than 500 μm, in a perpendicular axis to the vessel luminal surface. When referred to the stent struts it will be assumed that such distance of less than 500 μm will be measured between the centre of the abluminal surface of the strut and the abluminal point of the calcium, in the same perpendicular axis).and;
* Patients with good quality baseline OCT evaluation as judged by the investigators and;
* Patients who have been briefed on the study characteristics and have given their prior written informed consent.
Exclusion Criteria
* Patients with current ST-elevation Myocardial Infarction (STEMI).
* Patients with non-native lesion: stent restenosis, segment previously treated with drug eluting balloon, arterial or saphenous vein grafts.
* Patients with contraindication for the 1-month follow-up angiography and OCT:
* Glomerular Filtration Rate (GFR)\< 30 ml/min/1.72m2
* Contrast allergy
* Baseline post-stent control OCT failure, due to tortuosity or any other reason.
* Patient not candidate for a follow up angiography, due to frailty, non-cardiac disease or whatever other condition considered by the local team.
