Incessant ventricular tachycardia acutely controlled with intracoronary injection of radiographic contrast media

Management of patients with incessant monomorphic ventricular tachycardia is challenging. We report on 2 patients who had incessant ventricular tachycardia despite emergency treatment with antiarrhythmic drugs and repeated electrical cardioversions. In both cases, the arrhythmia was acutely terminated with intracoronary administration of radiographic contrast media, allowing hemodynamic stabilization. No tachycardia recurrences occurred.
