Abstract
In the percutaneous treatment of coronary stenoses, it is essential to take into account the presence of calcifications as this influences the short- and long-term post-procedural outcomes. Today in the catheterization laboratory, there are several tools for the treatment of calcium; exploiting the different operating mechanisms, possibly even combining them together, is part of a modern approach to coronary angioplasty that aims to optimize results. To this end, each procedure must be properly planned and, in this perspective, intracoronary imaging (such as optical coherence tomography and intravascular ultrasound) is an essential aid to guide the procedure and show results.
