Abstract/OtherAbstract:
Although rotational atherectomy (RA) is used for complex lesions in percutaneous coronary intervention, there are several contraindications and precautions. The purpose of our study was to compare complications between off-label and on-label use of RA. We identified 250 consecutive patients who underwent RA. Off-label characteristics included saphenous vein graft lesions, presence of thrombus, unprotected left main stenosis, coronary artery dissection, acute myocardial infarction (MI), left ventricular dysfunction, 3-vessel disease, long lesion (≥25 mm), or angulated lesion (≥45°). Patients who had ≥1 off-label characteristic were assigned to the off-label group (156 patients), and patients who had no off-label characteristics were assigned to the on-label group (94 patients). Occurrence of slow flow or periprocedural MI in the off-label group was higher than that in the on-label group (slow flow 30% vs 18%, p = 0.06; MI 8.8% vs 2.1%, p = 0.04), whereas severe complications such as burr entrapment, transection of the guidewire, or perforation were rare in the 2 groups. In conclusion, compared to the on-label group, the off-label group had a higher incidence of slow flow and periprocedural MI. Severe complications such as burr entrapment, transection of the guidewire, or perforation were rare in the 2 groups.
