Authors' conclusion

3D late gadolinium enhancement cardiac magnetic resonance can identify SCAI with excellent accuracy and may refine non-invasive risk stratification and patient selection for invasive EAM in tetralogy of Fallot.

Study context

Population
Consecutive patients with repaired tetralogy of Fallot who underwent right ventricular electroanatomical mapping (RV-EAM) and 3D-LGE-CMRderivation 48
Comparison
3D-LGE-CMR vs Risk scores
Outcome
Diagnostic performance of 3D-LGE-CMR to non-invasively identify slow-conducting anatomical isthmuses (SCAI)
