NCT02274246

Brief Summary

The purpose of this study is to validate the technique for the detection of left atrial fibrosis through segmentation of endocardial and epicardium landmarks of the images obtained with 3 Tgadobutrol-enhanced magnetic resonance with the software GIMIAS® in a cohort of healthy volunteers, without atrial fibrillation or known cardiovascular risk factors.

Secondary Outcomes (2)

  • Adverse events

    1 week after intervention

  • Interobserver variability in the generation of segmented images of left atrium, measured through the kappa index.
