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 vessels. In cases with heavily calcified lesions, high-pressure, non-compliant balloon inflations may still fail to dilate adequately and prepare a heavily calcified vessel for stent delivery. This activity reviews the indications, contraindications, and complications of rotational atherectomy and highlights the r...
