Rotational atherectomy techniques have evolved toward lesion modification to facilitate balloon angioplasty and stenting, underpinning major advances in procedural safety.
This expert review provides contemporary consensus and recommendations on optimal rotational atherectomy techniques for managing calcified coronary lesions.
Rotational atherectomy (RA) is an established tool in interventional cardiology for treatment of calcified coronary lesions. Over 3 decades of clinical experience and research, techniques have matured and outcomes have improved. Heterogeneity exists, however, in RA utilization and technique. We assembled a group of experienced RA operators and device experts to summarize and critique key elements of contemporary RA technique, to identify areas of consensus and controversy, and to offer recommendations for optimal performance for the practicing interventional cardiologist. Evolution in RA strategy toward a focus on lesion modification to facilitate balloon angioplasty and stenting has underpinned major advances in procedural safety, including opportunity to use smaller caliber equipment and radial access. Optimal technique and improved safety have permitted exploratory use of RA for different lesion types and reevaluation of procedural requirements, including flush solution composition and transvenous pacing. Preparedness to manage complications remains paramount and recommendations for operators and institutions are outlined.
