The reentry circuit of idiopathic left ventricular tachycardia (ILVT) has been demonstrated to be confined to the left posterior Purkinje network. We hypothesized that mapping and linear ablation of the left posterior fascicle (LPF) during sinus rhythm guided by non-contact mapping can effectively modify the arrhythmogenic substrate in patients with ILVT and abolish the tachycardia. ⋯ Mapping and linear ablation of the Purkinje network in LPF area guided by non-contact mapping is an effective and safe treatment of ILVT with radiofrequency energy, especially for those ILVTs which were unsuccessfully treated by conventional means or were non-inducible or non-sustained during the procedure.
