EchoFocus-CHD is a multi-task AI model that automatically detects 12 critical and 8 non-critical congenital heart lesions on standard echocardiography. On an external cohort the model matched expert interpretation — with the promise of extending scarce paediatric echo expertise beyond academic centres. A concrete example of where AI-assisted imaging can rapidly deliver clinical value in primary care and smaller hospitals.
Background: Delayed or missed diagnosis of congenital heart disease (CHD) contributes to excess pediatric mortality worldwide. Echocardiography (echo) is central to diagnosing and triaging CHD, yet expert interpretation remains a scarce and maldistributed global resource. Artificial intelligence (AI) offers the potential to democratize diagnostics and extend expert-level interpretation beyond large academic centers, but its application in CHD remains underexplored.Methods: We developed EchoFocus-CHD, an AI-enabled model for automated detection of 12 critical and 8 non-critical CHD lesions, individually and as composites. The composite critical CHD outcome was the primary endpoint. The model expands on a multi-task, view-agnostic architecture (PanEcho) with a transformer encoder to improve focus on relevant echo views. The model was internally trained (80%) and tested (20%) on the first echo per patient from Boston Children’s Hospital (BCH), with further evaluation on a referral cohort
