In-hospital and intermediate term outcome of ventricular tachycardia storm.

Real world data on management and outcomes of ventricular tachycardia (VT) storm are scarce. This prospective study evaluates the clinical profile, in-hospital outcome and intermediate outcome in patients presenting with VT Storm. A majority (36/50, 72%) were male and the age was 54 ± 15 years. Scar VT was the most common underlying substrate for VT stormand pleomorphic VT was the predominant morphology. Twenty-one (42%) patients underwent cardiac sympathetic denervation, 6 (12%) patients underwent radiofrequency ablation (RFA), 3 (6%) patients amongst these underwent both the precedures in addition to conventional medical management. The overall mortality was 18% and VT free survival was 54%at 6 months follow up. VT recurrence was more common with severe LV dysfunction.
