Intravascular ultrasound-guided shockwave treatment of stents overlapping underexpansion of calcified left anterior descending artery.

ABSTRACT: Heavily calcified lesions may limit optimal stent deployment resulting in stent underexpansion, thus increasing the risk of restenosis and thrombosis. We describe the case of overlapping stents underexpansion treated with a shockwave intravasuclar lithoplasty system (Shockwave Medical Inc., Santa Clara, CA, USA). A 65-year-old man with angina, underwent coronary angiography and intravascular ultrasound showing restenosis, in a site of overlapping stents, due to calcified tissue. Shockwave lithoplasty balloon was able to break calcified tissue in a site of overlapping stents, allowing subsequent vessel dilation and repeat stent implantation with optimal final stent expansion. Heavily calcified lesions may limit optimal stent deployment resulting in stent underexpansion.
