Impella-Assisted Intracoronary Lithotripsy Of Severely Calcified Left Main Coronary Artery Bifurcation For Nstemi With Cardiogenic Shock

High calcification of coronary artery plaque is a frequent cause of suboptimal stent expansion, which can result in stent thrombosis and restenosis. Shockwave intravascular lithotripsy (S-IVL) represents a new frontier in the treatment of highly calcified coronary lesions. It can be an excellent alternative to intracoronary atherectomy in extremely high-risk lesions. We present a case of a 57-year-old man with known severe coronary artery disease (CAD) who presented with non-ST segment elevation myocardial infarction (NSTEMI), cardiogenic shock and was successfully treated with impella-assisted shockwave-intravascular lithotripsy permitting successful percutaneous intervention of a high-risk left main coronary artery (LMCA) bifurcation in-stent restenosis.
