We report the case of a stent under-expansion due to heavily calcified plaque treated with the shockwave lithoplasty system. A 77-year-old woman underwent coronary angiography, and intravascular ultrasound revealed stent under-expansion due to calcified plaque. Shockwave lithoplasty balloon was used to disrupt calcium deposits around the stent, thereby allowing a correct stent expansion with an excellent angiographic and intravascular ultrasound result.
