Percutaneous endocardial radiofrequency catheter ablation targeting abnormal Purkinje-related triggering VPCs can successfully eliminate drug-refractory electrical storm following emergent CABG.
May offer bailout for refractory post-CABG storm; leaves open need for prospective validation.
Electrical storm is a rare but critical complication following revascularization in patients with ischemic heart disease. We report the case of a 67-year-old man who developed drug refractory intractable electrical storm after emergent coronary artery bypass grafting for ischemic cardiomyopathy. The electrical storm was successfully eliminated by percutaneous endocardial radiofrequency catheter ablation targeting the abnormal Purkinje-related triggering ventricular premature contractions in a low-voltage zone.

Tokunaga et al. (2015) conducted a case report in Intractable electrical storm after coronary artery bypass grafting for ischemic cardiomyopathy (n=1). Percutaneous endocardial radiofrequency catheter ablation was evaluated on Elimination of electrical storm. Percutaneous endocardial radiofrequency catheter ablation successfully eliminated drug-refractory intractable electrical storm in a 67-year-old man following emergent coronary artery bypass grafting.
