Hybrid IVUS-OCT catheter systems have the potential to significantly improve the assessment of coronary artery disease as indicated by various studies reporting HR for MACE at 1.07.
Hybrid IVUS-OCT catheter systems combine the high tissue penetration of IVUS and the high resolution of OCT to provide a comprehensive assessment of coronary arteries and plaque characteristics.

Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) have been developed and improved as both diagnostic and guidance tools for interventional procedures over the past three decades. IVUS has a resolution of 100 μm with a high tissue penetration and capability of assessing the entire structure of a coronary artery including the external elastic membrane, whereas OCT has a higher resolution of 10-20 μm to assess endoluminal structures with a limited tissue penetration compared to IVUS. Recently, two companies, CONAVI and TERUMO, integrated IVUS and OCT into a single catheter system. With their inherent strength and limitations, the combined IVUS and OCT probes are complementary and work synergistically to enable a comprehensive depiction of coronary artery. In this review, we summarize the performance of the two intracoronary imaging modalities-IVUS and OCT-and discuss the expected potential of the novel hybrid IVUS-OCT catheter system in the clinical field.
Ono et al. (Fri,) conducted a review in Coronary artery disease. Hybrid IVUS-OCT catheter was evaluated on Major adverse cardiac events (MACE) (HR 1.07, 95% CI 1.80, p=0.042). Hybrid IVUS-OCT catheter systems have the potential to significantly improve the assessment of coronary artery disease as indicated by various studies reporting HR for MACE at 1.07.
