Idiopathic Ventricular Tachycardia (IVT) in children requires a rapid and accurate diagnosis as well as appropriate care. We herein describe a patient with an uncommon IVT and premature ventricular contractions arising from the tricuspid annulus and evaluate the outcome of radiofrequency ablation site therapy in children.
A 15-year-old boy was admitted to the emergency department with a complaint of palpitation. The patient had a history of ablation therapy for VT in the right ventricular outflow tract 3 years previously and recurrent episodes of accelerated idioventricular rhythm or slow VT since then. The palpitation was not responsive to antiarrhythmic drugs. Structural heart disease was excluded by normal echocardiography. Arrhythmogenic right ventricular dysplasia and LV (Left Ventricular) non-compaction were excluded by cardiovascular magnetic resonance imaging. Given the patient’s unresponsiveness to medical treatment, an electrophysiological study was performed, and the slow VT with a tricuspid annular origin was ablated successfully.
