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.
