To develop an MRI-based training model for left atrial appendage (LAA) closure that allows for the demonstration of optimal transeptal puncture (TSP) sites and training for interventionalists.
Key Findings:
The model allows for training on various TSP sites and LAA shapes.
MRI data provided sufficient accuracy for segmentation of cardiac structures.
The training model can be easily replicated in different medical facilities.
Interpretation:
The MRI-based training model enhances procedural planning and training for LAA closure, addressing the variability in patient anatomy and TSP site selection.
Limitations:
Current individualization is limited to LAA and fixed atrial models.
Further customization requires additional 3D printing of patient-specific anatomy.
Conclusion:
This MRI-based training model serves as a valuable tool for interventionalists, improving training and procedural outcomes in LAA closure.
