Abstract:Background: Percutaneous coronary intervention (PCI) for lesions with calcified nodules (CNs) is associated with worse outcomes than PCI for other calcified lesions. We aimed to clarify the relationship between CNs at index PCI, optical coherence tomography (OCT) findings at 8-month follow-up, and clinical outcomes using serial OCT. Methods This retrospective observational study utilized data from a prospective, single-center registry. We conducted consecutive PCI for calcified lesions requiring rotational ath… Show more
