Key result
Coil embolization of collateral arteries linked to Takotsubo cardiomyopathy in a two-year-old single right ventricle patient.
Takotsubo cardiomyopathy can occur as a complication following transcatheter coil embolisation in pediatric patients with single ventricle physiology.
May warrant monitoring for Takotsubo after coil embolisation in pediatric single-ventricle physiology; hypothesis-generating before Fontan.
Takotsubo cardiomyopathy can be triggered by stress. We report a 2-year-old boy with a single right ventricle after bidirectional Glenn surgery who developed Takotsubo cardiomyopathy following coil embolisation of collateral arteries and subsequently underwent successful Fontan completion.
