Eruptive calcified nodules (CNs) are a manifestation of severely calcified plaques, which exist in acute coronary syndrome (ACS), non-ACS lesions. Optical coherence tomography is crucial for diagnosing and treating eruptive CNs in clinical practice. Management of eruptive CNs is still a challenge for interventional cardiologists. There have been significant advances in the treatment of eruptive CNs such as intravascular lithotripsy, excimer laser coronary atherectomy, rotational atherectomy, and orbital atherectomy. We find a range of treatment modalities to be effective under different conditions. The selection of these devices should be considered based on guidewire position, lesion characteristics, clinical manifestations, and operator's experiences.
