When Rotational Atherectomy is not Enough

Severe coronary calcification predicts stent under-expansion, malapposition, and poor outcomes in percutaneous coronary intervention. Rotational atherectomy permits debulking of coronary calcium allowing for stent expansion. More recently, intravascular lithotripsy has been used to fracture calcium and aid revascularization. Here we report two cases where both strategies were required for revascularization.
