The role of rotational atherectomy in contemporary chronic total occlusion percutaneous coronary intervention

Key Points

• Rotational atherectomy is performed infrequently (∼3.5%) during chronic total occlusion (CTO) percutaneous coronary intervention (PCI) for two indications: treatment of balloon uncrossable and balloon undilatable lesions.
• Use of rotational atherectomy in CTO PCI was associated with high success and acceptable complication rates.
• Rotational atherectomy remains a “must have” device for interventional cardiologists performing complex PCI.
