Key result
Continuous stellate ganglion blockade stabilizes refractory VT storm in a pediatric ECMO patient.
Why the study?
Pharmacologic autonomic modulation and left cardiac sympathetic denervation may not be effective or practical for emergent treatment of VT storm in pediatric patients with long-QT syndrome.
Does continuous stellate ganglion blockade stabilize rhythm in a pediatric patient with drug-refractory VT storm and prolonged QT on ECMO?

Does continuous stellate ganglion blockade stabilize rhythm in a pediatric patient with drug-refractory VT storm and prolonged QT on ECMO?
Continuous stellate ganglion blockade may be an effective emergent treatment for drug-refractory VT storm in pediatric patients with prolonged QT on ECMO.
May stabilize refractory pediatric long-QT VT storm; leaves open efficacy, safety, and generalizability.
Ventricular tachycardia (VT) storm, defined as recurrent VT requiring electrical cardioversion ≥3 times within 24 hours, is a rare presentation of long-QT syndrome. Pharmacologic autonomic modulation and/or left cardiac sympathetic denervation are established therapies in long-QT syndrome in adults but may not be effective or practical in the emergent treatment of VT storm. We present a novel case of a child with drug-refractory VT storm and prolonged QT requiring extracorporeal membrane oxygenation (ECMO) support. Continuous stellate ganglion blockade was remarkably effective in stabilizing his rhythm and should be considered in similar pediatric cases.

Franklin et al. (2019) conducted a case report in Ventricular tachycardia storm and prolonged QT requiring ECMO support (n=1). Continuous stellate ganglion blockade was evaluated on Rhythm stabilization. Continuous stellate ganglion blockade was remarkably effective in stabilizing the rhythm of a pediatric patient with drug-refractory ventricular tachycardia storm on ECMO support.
