Does extensive myocardial LGE (≥9.9% of LV mass or ≥6 LV segments) on MRI predict a high risk of sudden cardiac death in patients with cardiac sarcoidosis?
MRI-detected LGE of ≥9.9% LV mass or ≥6 segments may identify cardiac sarcoidosis patients at high risk for sudden cardiac death, though prospective validation is required.
In cardiac sarcoidosis, myocardial LGE making up ≥9.9% of LV mass or affecting ≥6 LV segments may suggest prognostically significant LV involvement and a high risk of SCD. However, prospective validation of the thresholds is needed.
Pöyhönen et al. (Fri,) studied this question.
