Management of Uncommon Idiopathic Idio-Ventricular Rhythm of Tricuspid Origin in 15 years Old Boy: A Case Report Author: Elio Caruso, Mohammadrafie Khorgami, Farzad Kamali, Farruggio Silvia, Negar Omidi
ABSTRACT
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.
