Rotational atherectomy for calcified lesions during ST-segment elevation myocardial infarction: a case series and literature review.

Background: ST elevation myocardial infarction (STEMI) has traditionally been a relative contraindication for the utilization of rotational atherectomy (RA). However, in severely calcified lesions, RA may be necessary to facilitate stent delivery.

Case Summary: Three patients who present with STEMI are found to have severely calcified lesions on intravascular ultrasound. Equipment was unable to pass the lesions in all three cases. Rotational atherectomy was therefore performed to allow for stent passage. All three cases had achieved successful revascularization with no intraoperative or post-operative complications. The patients remained angina-free the rest of their hospitalization and at the 4 month follow-up.

Discussion: Rotational atherectomy for calcific plaque modification during STEMI when equipment will not pass is a feasible and safe therapeutic option.
