    Ebstein anomaly is characterized by tricuspid valve displacement, atrialisation of the right ventricle, and tricuspid regurgitation.

  • 2

    Exercise capacity in patients with Ebstein anomaly is linked to echocardiographic and cardiac MRI parameters of disease severity.

  • 3

    The study evaluated cardiac output during exercise in un-operated patients with Ebstein anomaly using cardio-pulmonary exercise testing and cardiac MRI.

  • 4

    Thirteen un-operated patients with Ebstein anomaly participated in the study, which adhered to ethical guidelines and received institutional approval.

  • 5

    Cardiac index was calculated from aortic and pulmonary artery flow data at rest and during exercise to assess cardiac performance.
