Key result
Left stellate ganglion block resolves refractory ventricular electrical storm post-CABG in a single patient.
Why the study?
Ventricular arrhythmias after CABG can be life-threatening and may be refractory to standard antiarrhythmic therapy.

May support SGB as rescue therapy for refractory post-CABG ventricular storm; hypothesis-generating and requires prospective validation.
Ventricular arrhythmias after coronary artery bypass grafting (CABG) can be life-threatening. A 66-year-old man undergoing robotic-assisted CABG developed a refractory ventricular electrical storm on the 2 nd post-operative day, unresponsive to antiarrhythmic therapy. Angiography on the 3 rd post-operative day showed thrombotic occlusion of the native right coronary artery. Percutaneous coronary intervention restored flow, but ventricular ectopy persisted. A left stellate ganglion block (SGB) resolved the arrhythmia, enabling antiarrhythmic taper and discharge. This case highlights SGB as an effective rescue therapy for refractory ventricular arrhythmias.

Dash et al. (2026) conducted a case report in Refractory ventricular arrhythmias (n=1). Left stellate ganglion block was evaluated on Resolution of ventricular arrhythmia. Left stellate ganglion block successfully resolved refractory ventricular electrical storm in a patient following robotic-assisted off-pump CABG, allowing for antiarrhythmic taper and discharge.
