Influence of Vessel Wall Calcification on Early Stent Strut Healing

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;
