title: [Radiofrequency catheter ablation of idiopathic ventricular tachycardia originating from the mitral annulus].
abstract: Idiopathic ventricular tachycardias (VT) originate mostly from the right ventricular outflow tract and rarely from the mitral annulus. Herein, we present a 20-year-old male patient in whom we performed a successful radiofrequency catheter ablation of mitral annular VT. He admitted to our department with the complaints of palpitations and shortness of breath attacks for 5 years. Detailed assessment disclosed idiopathic VT which subsequently was found to be derived from the mitral annulus in electrophysiologic study. The patient's symptoms disappeared after successful RF ablation and the follow-up Holter ECG was totally normal.
