Real-time deep learning interpretation of echocardiographic video for automated detection of anatomical features associated with tetralogy of fallot in pediatric patients : a feasibility study
This study presents a real-time deep learning model for automated detection of Tetralogy of Fallot (TOF) anatomical features in pediatric echocardiographic videos. Utilizing Detectron2 and Mask R-CNN, the model was trained on echocardiograms from 174 pediatric patients, achieving an AUC of approximately 1.00 and an F1 score of 96.8%. It demonstrated high sensitivity, precision, and over 97% accuracy in distinguishing TOF across multiple videos, suggesting significant potential as a screening tool in resource-limited settings and for reducing the workload of pediatric cardiologists.

Real-time Clinical Application
A pediatric cardiologist in a remote clinic uses the AI model during an echocardiogram. The AI system processes video frames in real-time (1.45 to 5.98 fps), overlaying detected features like a VSD with 96% confidence and pulmonary stenosis with 98% confidence. When all four key components of TOF (AO, VSD, RVOTO, RVH) are identified, the system flags a TOF diagnosis. This immediate feedback helps guide the less experienced practitioner to a precise diagnosis, supporting timely intervention.
- ✓ Improved Accessibility: Enables early and accurate diagnosis in regions with limited specialist access.
- ✓ Reduced Workload: Acts as a screening tool, allowing pediatric cardiologists to focus on complex cases.
- ✓ Enhanced Accuracy: Provides objective, frame-level detection of anatomical features, reducing diagnostic variability.
- ✓ Real-time Support: Integration into live echocardiography workflows offers immediate decision support.
