Radiofrequency catheter ablation of multiple haemodynamically unstable ventricular tachycardias in a patient with surgically repaired tetralogy of Fallot

Abstract
A patient with repaired tetralogy of Fallot presented with recurrent syncope and had multiple haemodynamically unstable ventricular tachycardias unresponsive to antiarrhythmic medications. Ventricular tachycardias became haemodynamically tolerated with amiodarone, procainamide and dopamine, permitting activation and entrainment mapping. Radiofrequency ablation of three tachycardia circuits was performed. Ventricular tachycardia could not be induced 1 week, and 3 and 9 months later. Radiofrequency ablation is feasible for multiple, haemodynamically unstable ventricular tachycardias in repaired tetralogy of Fallot.
