Optical Coherence Tomography-guided Coronary Intervention and Optimal Use of Dual Anti-Platelet Therapy In Patients With Complex Lesions (OCCUPI Trial)
There is no definite conclusive work about optimal duration of DAPT after PCI of complex lesions, which have been left at each operator's discretion. It is needed to be investigated how optimal duration of dual antiplatelet therapy will be decided in complex lesions. Also, the benefit of OCT-guided PCI assuming better stent optimization should be determined in complex PCI. In the study, we will explore the clinical implication of OCT-guided PCI of complex lesions. Optimal duration of DAPT after PCI of complex lesions with or without OCT-guidance will be also investigated.
