This article by Nazarian et al in this week's issue of Circulation shows that scar diagnosed on contrast-enhanced CMR is significantly predictive of inducible ventricular tachycardia, even after adjusting for LV ejection fraction.
Scar involving 26-75% of the myocardium was predictive and can identify high-risk individuals.
A case highlighting this issue has been published in our accompanying images blog.
