Does MRI-detected delayed enhancement identify the risk of ventricular arrhythmias in patients with cardiac sarcoidosis and preserved or mildly reduced left ventricular function?
MRI-detected delayed enhancement is a useful risk stratification tool for predicting ventricular arrhythmias in patients with cardiac sarcoidosis and preserved or mildly reduced ejection fraction.
RV DE in patients with cardiac sarcoidosis is associated with a risk of adverse events in patients with cardiac sarcoidosis and preserved ejection fraction in the absence of a prior history of VT. Patients with DE and a prior history of VT have a high VT recurrence rate. Patients without DE on MRI have a low risk of VT.
Crawford et al. (Tue,) studied this question.
