Summary
Advancements in medical imaging and navigation systems enhance catheter-based structural heart disease treatments. Multimodal imaging improves procedural accuracy, but real-time guidance remains a key challenge for future research.
Area of Science:
- Cardiovascular Imaging
- Medical Navigation Systems
- Structural Heart Disease Interventions
Background:
- Catheter-based treatments for structural heart diseases (SHD) have surged, driven by advanced medical imaging and navigation.
- Multimodal cardiac imaging is vital for accuracy and outcomes but faces integration challenges.
Purpose of the Study:
- To review state-of-the-art image-based medical navigation systems for catheter-based cardiac procedures.
- To analyze methodologies and advancements from 2019-2023.
Main Methods:
- Systematic review of 44 articles (2019-2023) on catheter-based cardiac procedures.
- Categorization of methodologies into Image Enhancement/Tracking, Fusion/Reconstruction, 3D Modeling/Printing, Extended Reality, and AI.
Main Results:
- Multimodality imaging is prevalent, enhancing accuracy in procedures like LAAC, TAVI, and ablation.
- Combinations of fluoroscopy, ultrasound, and CT enable real-time guidance and precise navigation.
Conclusions:
- Integrated multimodal imaging improves diagnostic reliability and procedural success for SHD.
- Real-time surgical guidance is a critical area requiring further research and development.
