Calcium deposits within a coronary artery are a harbinger of previous inflammation, healing, and scarring. Significant calcification is synonymous with significant atherosclerotic coronary artery disease (CAD). Coronary calcification can be spread diffusely throughout coronary arteries, during imaging of the vessel significant calcification can encompass the vessel in a 360-degree manner. Coronary stenoses with circumferential or significant vessel calcification are rigid and frequently not dilatable with use of conventional balloon angioplasty. Often stent dilation and maximal vessel wall apposition are compromised in extensively calcified coronary lesions, stents deployed in heavily calcified vessels without atherectomy tend to thrombose, restenosis, and could cause stent fracture. Significant calcification remains a major limitation of balloon angioplasty as well as successful stent delivery to severely affected ...
