Abstract

A 29-year-old gravida1 para1 woman presented with increasing fatigue. Multi-modality imaging demonstrated the left coronary artery arising from the main pulmonary artery with large collateral vessels in the interventricular septum, in keeping with unrepaired anomalous left coronary artery from the pulmonary artery. Cardiac MRI T1 mapping demonstrated globally elevated non-contrast T1 and extracellular volume fraction values, which suggested the presence of diffuse interstitial myocardial fibrosis. Cardiac MRI T1 mapping allows for a new dimension of myocardial characterisation, providing insight into subtle, diffuse abnormalities at the tissue level.
