HF-OCT Imaging System and Vis-Rx® PRIME
Micro-Imaging Catheter
Discover how high-frequency OCT technology helps physicians visualize coronary anatomy and guide confident treatment decisions
Guidelines support intravascular imaging, and pre-PCI OCT impacts procedural decision-making
Coronary artery disease is becoming increasingly complex. Despite growing clinical guideline support for intravascular imaging in PCI, treatment decisions before stenting are often still made with limited vessel insight.
OCT drives PCI decision-making:
-
80% of OCT-driven treatment changes occur before PCI¹, yet most imaging systems were not designed for pre-PCI workflow
-
OCT influenced physician decision-making in 86% of lesions compared with angiography alone¹
Effective PCI planning starts with imaging that crosses before treatment, visualizes the full vessel, and works quickly without disrupting workflow.
The impact of HF-OCT
HF-OCT is designed to give interventional cardiologists vessel insight before PCI. By visualizing plaque characteristics, vessel size, and lesion morphology, it supports informed treatment planning, with a system designed for fast setup and easy use in the cath lab.
World’s smallest imaging catheter
At 0.6mm (1.8F), the Vis-Rx PRIME catheter can cross tight lesions and clear the vessel without pre-dilation2, helping physicians assess anatomy before committing to a treatment strategy.
Fast 1-second pullback speed
HF-OCT’s high-speed laser captures detailed images in just one second, enabling rapid vessel assessment.
Image the entire coronary artery in a single pullback
Capture up to 100 mm, 33% longer than other OCT systems, enabling complete coronary imaging in just one pullback.2
Actionable insights without workflow disruption
The system sits outside the sterile field and requires no additional draping, making setup simple and efficient.
Lower contrast burden
The catheter’s small profile, fast pullback, and saline compatibility help minimize contrast use while maintaining high-quality vessel imaging.3
AI-powered analysis
Automated measurements and stent analysis provide real-time guidance, supporting rapid and informed decision-making.
Discover how HF-OCT works
Clinical impact of image-guided PCI
OCT uncovers suboptimal stent deployment in 31%
of angiography-guided cases, which is associated with a 4× higher risk of MACE at follow-up4
OCT-guided PCI achieves superior stent expansion and procedural success
than angiography alone5
IVI-guided PCI lowers the risk of cardiac death or target-vessel MI by 37%
compared with angiography-only guidance6
OCT/IVI-guided stent implantation reduces major adverse outcomes,
including death, MI, repeat procedures, and stent thrombosis7
