To the Editor:
We read with great interest the article by Halliday and colleagues1 that was published in the May 30, 2017, issue of Circulation. The authors demonstrated that patients with mild-to-moderate left ventricular (LV) dysfunction and late gadolinium enhancement (LGE) during cardiac magnetic resonance imaging are at increased risk of sudden cardiac death and may benefit from implantation of a defibrillator. Similarly, a recent meta-analysis2 reported that ventricular arrhythmias and sudden cardiac death more frequently occur in patients with LGE, regardless of LV ejection fraction (<35% or >35%). Recently, …
