Background: Optical coherence tomography (OCT) is reported to be a feasible and safe imaging modality for the guidance of percutaneous coronary intervention (PCI) of complex lesions. Methods: This multicenter, prospective registry assessed the minimum stent area (MSA) achieved under OCT guidance. A performance goal of 24% improvement in MSA over and above the recommendation set by the European Association of Percutaneous Cardiovascular Interventions Consensus 2018 (4.5 mm 2 MSA for non-left main and 3.5 mm 2 for small vessels). The incidence of contrast-induced nephropathy was also assessed.
Core lab analysis was conducted. Results: Five hundred patients (average age: 59.4 ± 10.1 years; 83% males) with unstable angina (36.8%), STEMI (26.4%), and STEMI (22%) were enrolled. The primary endpoint was achieved in 93% of lesions with stent diameter ≥2.75 mm (average MSA: 6.44 mm 2 ) and 87%…
