Underexpansion of coronary stents represents an increased risk for subsequent stent thrombosis. Rotational artherectomy is now a commonly used technique to reduce the calcium burden in heavily calcified plaques prior to stent deployment. However, once deployed in such plaques prior to rotablation, stent underexpansion may be a challenge and dilemma exists on how best to deal with this clinical situation. In this report we describe a case where an underexpanded stent due to a heavily calcified plaque was successfully treated with stentablation, allowing for full stent expansion afterwards.
