Image-Based Medical Navigation Systems for Cardiac Interventions: Recent Technological Advances
Authored by Luís C. N. Barbosa, João L. Vilaça, Siobhán Moane, Pedro Morais and published on March 30, 2026, this research explores the cutting-edge of AI and imaging in cardiac surgery.
Revolutionizing Cardiac Interventions with AI-Driven Navigation
This comprehensive review highlights the rapid advancements in image-based medical navigation systems for catheter-based cardiac procedures, driven largely by multimodal imaging and artificial intelligence. The integration of various imaging modalities—such as fluoroscopy, ultrasound, CT, and MRI—is crucial for enhancing diagnostic accuracy, improving interventional effectiveness, and optimizing clinical outcomes for structural heart diseases (SHD). While significant progress has been made in image enhancement, tracking, fusion, 3D modeling, extended reality, and AI, challenges persist in real-time synchronization of multimodal data and ensuring robust, generalizable AI models. The future points towards intelligent, interoperable systems that can provide context-aware guidance and automate workflows, ultimately leading to safer, more efficient, and personalized cardiac interventions.

Enhanced Diagnostic Accuracy & Procedural Efficiency
This area focuses on integrating 3D anatomical models, typically derived from pre-procedural CT or MRI scans, with real-time imaging modalities such as fluoroscopy and ultrasound. This combination enables enhanced anatomical understanding and device guidance, leading to significantly reduced procedure time, radiation exposure, and contrast agent use in interventions like LAAC and PCI. Key techniques involve rigid and deformable registration algorithms, often leveraging TEE probe pose detection for dynamic adjustment.
Personalized Pre-Procedural Planning & Training
Patient-specific 3D-printed cardiac models, generated from CT, MRI, or echocardiographic data, serve as crucial tools for interventional planning, clinician training, and device sizing. These physical phantoms, often made from flexible silicone, allow for hands-on practice in a realistic cath lab environment, which has been shown to reduce fluoroscopy time and improve procedural accuracy. Recent advances aim to integrate AI for automated segmentation, overcoming the manual bottleneck in model generation.
Intuitive Real-time Procedural Guidance
XR technologies, including virtual, augmented, and mixed reality, enhance procedural guidance by integrating computational environments with the real world. Utilizing head-mounted displays and body tracking, XR systems provide 3D anatomical visualizations, support real-time MR guidance, and facilitate AR guidance for transcatheter procedures. Applications range from advanced training simulators to intra-operative support, improving spatial understanding, reducing procedure times, and enhancing ergonomic efficiency for clinicians.
Transformative Automation Across the Workflow
AI and deep learning techniques are transformative drivers in image-guided cardiac interventions, enhancing image processing, device tracking, and procedural support. Key applications include patient-specific dynamic coronary roadmapping (DCR), real-time catheter detection and segmentation in various modalities (X-ray, US, MRI), 3D catheter localization, and advanced X-ray image denoising. AI enables automatic segmentation, motion compensation, and predictive navigation, significantly reducing operator variability and improving patient safety.
