Article Synopsis
  • The study seeks to improve risk stratification for patients with congenital heart disease (CHD) by using an AI-enhanced electrocardiogram (ECG) tool, addressing a significant gap in current medical practice.* -
  • A convolutional neural network was developed and tested on a large set of ECGs from patients at Boston Children's Hospital to predict 5-year mortality, showing good performance compared to traditional indicators like age and heart function metrics.* -
  • The model displays potential for timely risk assessment across various ages and types of CHD, helping to guide future monitoring and therapeutic interventions for patients.*

Electrocardiogram-Based Deep Learning to Predict Mortality in Repaired Tetralogy of Fallot.

JACC Clin Electrophysiol

Department of Cardiology, Boston Children's Hospital, Boston, Massachusetts, USA; Department of Pediatrics, Harvard Medical School, Boston, Massachusetts, USA. Electronic address:

Background: Artificial intelligence-enhanced electrocardiogram (AI-ECG) analysis shows promise to predict mortality in adults with acquired cardiovascular diseases. However, its application to the growing repaired tetralogy of Fallot (rTOF) population remains unexplored.

Objectives: This study aimed to develop and externally validate an AI-ECG model to predict 5-year mortality in rTOF.

Background: AF risk estimation is feasible using clinical factors, inherited predisposition, and artificial intelligence (AI)-enabled electrocardiogram (ECG) analysis.

Objective: To test whether integrating these distinct risk signals improves AF risk estimation.

Methods: In the UK Biobank prospective cohort study, we estimated AF risk using three models derived from external populations: the well-validated Cohorts for Aging in Heart and Aging Research in Genomic Epidemiology AF (CHARGE-AF) clinical score, a 1,113,667-variant AF polygenic risk score (PRS), and a published AI-enabled ECG-based AF risk model (ECG-AI).
