The PICCOLETO IX PHENO Study

To investigate whether pre-procedural OCT-derived de novo coronary lesion phenotype (lipid-rich, fibrotic, calcific; and ACS mechanisms such as plaque rupture/erosion/calcified nodule) is associated with clinical outcomes after DCB angioplasty.

PICCOLETO IX PHENO is an investigator-initiated, multicenter, international, ambispective (retrospective and prospective) cohort study enrolling patients who underwent DCB angioplasty for de novo coronary artery disease with preprocedural OCT assessment of the target segment. OCT images (baseline mandatory; post-preparation and post-PCI when available) and angiography will be analyzed by independent core laboratories; clinical events will be adjudicated by an independent committee. The primary endpoint is clinically-driven target lesion revascularization at 12 months; secondary endpoints include device-oriented composite endpoint (cardiac death, TLR, target-vessel MI), target vessel revascularization, MI endpoints, and mortality.
