Cardiac tumors and thrombi

Percutaneous rotational coronary atherectomy (PRCA) facilitates stent delivery in diffuse, complex, heavily calcified lesions.1 In patients with acute coronary syndromes and especially in acute myocardial infarction (MI), PRCA may cause distal embolization of thrombus resulting in slow-flow or no-reflow.2,3 In patients with spontaneous or iatrogenic dissection, PRCA may cause perforation or extension of the dissection. Thus, PRCA is generally avoided in lesions that are thrombotic or dissected.
