Feasibility of three-dimensional artificial intelligence algorithm integration with intracardiac echocardiography for left atrial imaging during atrial fibrillation catheter ablation
Authors' conclusion
DL algorithm integration with ICE demonstrated considerable accuracy compared to CT and qualitative physician assessment.
Study context
- Population
- Patients undergoing atrial fibrillation (AF) ablation
- Participants
- 28 patients
- Comparison
- Deep learning (DL) algorithm with intracardiac echocardiography (ICE) vs cardiac computed tomography (CT)
- Outcome
