AI Article Synopsis
- Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) have evolved over the last 30 years as key diagnostic and guiding tools for heart procedures, each with unique strengths.
- IVUS provides good tissue penetration with a resolution of 100 μm, while OCT offers a higher resolution of 10-20 μm but has limited tissue penetration, making them complementary in assessing coronary arteries.
- Recent innovations have led to the development of a hybrid catheter system that combines IVUS and OCT, promising enhanced imaging capabilities for better understanding of coronary artery structures in clinical settings.
Article Abstract
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.
