Rapid prediction of cardiac activation in the left ventricle with geometric deep learning: a step towards cardiac resynchronization therapy planning
To develop geometric deep learning models for predicting activation time maps on left ventricular geometries to improve planning for cardiac resynchronization therapy (CRT).
Key Findings:
GINO model achieved 1.38% error on synthetic cases compared to 2.44% for GNN.
Both models demonstrated comparable performance on real-world LV geometries (GINO: 4.79% vs GNN: 4.07%).
The models can recover ground-truth parameters from noisy inputs effectively.
Interpretation:
The study indicates that geometric deep learning can enhance the precision of CRT planning by providing real-time predictions of cardiac activation, potentially leading to better patient outcomes.
Limitations:
Models were trained on synthetic data, which may not fully capture the complexity of real patient anatomies.
Performance on diverse patient populations and varying clinical scenarios needs further validation.
Conclusion:
The developed models show promise for improving CRT planning through personalized pacing site identification, paving the way for future clinical decision-support tools.
