In-hospital and intermediate term outcome of ventricular tachycardia storm

Abstract

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.

“…The condition is further characterized by return of the VT rhythm immediately after termination, such as in the case above 3,4 . If AICD is present, VT storm is then de ned as ≥ 3 ICD shocks or anti-tachycardia pacing events within the span of 24 hours 5 .…”

“…Rapid morphology recognition is needed to identify potentially reversible causes 1 . The majority (up to 84%) of patients present with monomorphic VT, usually secondary to previous infarct 3,5 . Patients with either poly-or pleomorphic VT are more likely associated with reversible etiologies such as acute ischemia, electrolyte abnormalities, and medications (missed or proarrhythmic).…”

“…In-hospital mortality can be as high as 19.5% 5 . 6-month mortality involves an additional 18% of patients, particularly those age > 50 and with prior infarct 5 . Up to 46% experience VT recurrence at 6 months; patients with LVEF < 30% are at greatest risk 5 .…”

Amiodarone and Lidocaine Infusion for Treatment of Ventricular Tachycardia Storm in an Emergency Setting: Case Report

“…The condition is further characterized by return of the VT rhythm immediately after termination, such as in the case above [3,4]. If AICD is present, VT storm is then defined as >3 ICD shocks or anti-tachycardia pacing events within the span of 24 hours [5]. Rapid morphology recognition is needed to identify potentially reversible causes [1].…”
