Abstract:

Background: Coronary calcified lesions may limit optimal stent deployment resulting in stent underexpansion, increasing the risk of thrombosis. The Shockwave Lithoplasty System, a new technology combining a balloon angioplasty catheter with the use of sound waves, it is able to break calcium deposits without affecting vascular soft tissue.

Case Presentation: An 80-year-old Caucasian man with ST elevation myocardial infarction underwent emergent coronary angiography showing complete intrastent thrombosis at the proximal trait of LAD. After thrombus removal, it was evident that stent under-expansion at its proximal edge was caused by vascular calcification. Coronary shockwave lithoplasty was chosen to treat this lesion. After calcium deposits disruption we were able to obtain complete stent expansion.

Conclusion: Our case demonstrates the usefulness and safety of the lithoplasty system in the context of ST elevation myocardial infarction.

Keywords: Coronary calcification, lithoplasty, STEMI, stent underexpansion, shockwave lithoplasty system, case report.
