Zorzi A, Mattesi G, Baldi E, et al. - The arrhythmic outcome of sudden cardiac arrest (SCA) survivors during follow‐up were determined and the prognostic value of myocardial edema (ME) on early cardiac magnetic resonance imaging, which denotes an acute and transient arrhythmogenic substrate, was tested.

• One hundred and one (71% men, median age 47 years) SCA survivors were included; the survivors underwent early (< 1 month) cardiac magnetic resonance imaging and received an implantable cardioverter‐defibrillator (ICD).

• Eighteen of 101 (18%) patients had ME as per T2‐weighted sequences.

• ME on early cardiac magnetic resonance imaging was identified to be linked with a favorable long‐term arrhythmic outcome of SCA survivors after adjustment for left ventricular ejection fraction and late gadolinium enhancement.

• The type of underlying heart disease did not correlate with the risk of appropriate ICD intervention.
