Ventricular arrhythmia burden in giant cell myocarditis remains poorly quantified; leaves open optimal ICD timing and selection.
Cohort (n=51)
Giant cell myocarditis carries a very high risk of life-threatening ventricular arrhythmias, exceeding 50% at 5 years, highlighting the potential benefit of ICD implantation in this population.
Ekström et al. (2016) conducted a cohort in Giant cell myocarditis (n=51). Giant cell myocarditis was evaluated on Sudden cardiac death (fatal or aborted). In patients with giant cell myocarditis, the cumulative incidence of sudden cardiac death was 26% at 5 years, and the composite risk of sudden cardiac death or ventricular tachycardia was 55%.
