Global Co-Creation with Local Insight: Siemens & Vivolight Medical’s DSA-OCT Integrated System, Ushering a New Era for intelligent Cathlab

On November 6, 2024, at the China International Import Expo in Shanghai, Siemens and Vivolight Medical jointly launched the world’s first DSA-OCT integrated multimodal diagnostic and therapeutic platform, the ARTIS icono floor. This innovative technology, a collaboration result between an international medical giant and a local pioneer, combines Digital Subtraction Angiography (DSA) and Optical Coherence Tomography (OCT) imaging, providing comprehensive vascular insights for physicians performing percutaneous coronary intervention (PCI). This integration improves diagnostic efficiency, enabling more precise PCI strategies for patients.

Current Clinical Situation

According to the 2023 China Cardiovascular Health and Disease Report, there are approximately 330 million people with cardiovascular disease in China. Cardiovascular diseases are the leading cause of death in the country, accounting for two out of every five deaths. It is estimated that by 2030, the proportion of people aged 65 and above will reach nearly 11% of the world’s total population. With China’s aging population, the prevalence of cardiovascular disease is expected to continue rising, and PCI remains a critical treatment approach.

DSA and OCT Technologies

DSA: Known as the "gold standard" for coronary artery disease diagnosis in PCI procedures, DSA reveals 2D images of vascular narrowing and blockages by injecting contrast agents. However, its external viewpoint limits information on internal vascular lesion.

OCT Technology: The "Third Eye" for Interventional Physicians

OCT (Optical Coherence Tomography) serves as the "third eye" for interventional physicians, addressing the limitations of DSA (Digital Subtraction Angiography). By inserting an imaging catheter into the blood vessel, OCT uses a high-speed rotating optical fiber to emit near-infrared light along the vessel wall, capturing high-resolution cross-sectional images of vascular microstructures.

• Preoperative Guidance: OCT helps identify plaque characteristics, enabling precise selection of stent size and length.
•  Intraoperative Assistance: It guides the accurate placement of stents.
• Postoperative Evaluation: OCT assesses issues such as edge dissections, stent expansion, and apposition, providing precise clinical decision support.

The 2023 European Society of Cardiology (ESC) Guidelines on Chronic Coronary Syndromes highlighted the importance of using OCT or IVUS (Intravascular Ultrasound) for imaging guidance in complex PCI procedures, awarding it the highest recommendation level of IA.

DSA-OCT Integration for Enhanced Efficiency

Traditionally, DSA (Digital Subtraction Angiography) and OCT (Optical Coherence Tomography) were used as independent systems, requiring frequent switching between devices. This process consumed valuable time, occupied cathlab space, and increased radiation exposure for medical staff. Additionally, the separate operation of these systems compromised PCI precision and efficiency.

The DSA-OCT Integrated Multimodal Diagnostic Platform offers transformative benefits for interventional procedures:

Clinical Benefits: Over 40% Improvement

Vivolight Medical’s Integrated OCT system has undergone extensive compatibility testing with Siemens' angiography machines across all models. By seamlessly integrating DSA and OCT imaging, the platform provides comprehensive anatomical and functional vascular insights. This enables tailored treatment plans and has demonstrated clinical benefits in over 40% of complex cardiac stent procedures.

Time and Space Efficiency

•  The integrated platform eliminates the need for frequent equipment switching, maintaining a ready-to-use state throughout the procedure.
• Simplified workflows significantly enhance PCI
• A compact, suspended design minimizes the platform's footprint in the Cathlab, while intelligently synchronized DSA and OCT imaging streamlines diagnostics.

Ease of Operation

Bedsides a tableside controller and a remote operation combination in the control room, this system also equipped with an OCT pullback trigger pedal, which enhance the operational efficiency and user experience.

This integration not only improves precision and outcomes for patients but also represents a major leap forward in the modernization of cathlab.

Vivolight Medical’s Future Vision: Advancing Smart Catheterization Rooms with AI-Powered Innovation
