Creation of Partial Fascicular Block: An Approach to Ablation of Idiopathic Left Ventricular Tachycardia in the Pediatric Population

Abstract: The technique of creating partial fascicular block appears to be a safe and effective approach to ablation of idiopathic left ventricular tachycardia in children.

“…The activation mapping combined with pace map was used in the EPS for mapping outflow tract VT (OTVT), papillary muscles VT (PMVT), and bundle branch reentrant VT . For the patients with FVT, mapping techniques include activation mapping, identification of diastolic potentials in tachycardia and in sinus rhythm, mapping of the Purkinje potentials, and pace mapping …”

“…The focal ablation target was the location with the earliest ventricular activation, or earliest leading Purkinje potential during the ongoing VT. In the ablation for the left posterior FVT, a line ablation across the left posterior fascicle was preformed …”

“…123 Ablation through the region of the posterior fascicle (or anterior fascicle, depending on the axis of the VT targeted) producing a QRS axis change as evidence of interruption of a portion of the fascicle was effective in one small series of six patients ages 3.5 to 17.5 years. 124 The results of a multicenter survey found ablation was attempted in 129 of 152 patients. 120 The procedure was successful in 71% of patients.…”

“…Potential complications in addition to those related to arterial catheterization and LV access include left bundle branch block (less than 1%) and rare AV block. 120,124,125 Ablation might be more difficult for the less common nonposterior fascicle variants. From a series of 16 patients with a median age of 9.5 years, 10 had typical posterior fascicular QRS morphology, and ablation was successful in all; however, two required two procedures.…”

“…in 14 ILVT patients, who likewise found a predilection for successful ablation sites in the posteroseptal region and near the posteromedial papillary muscle . However, there are clearly exceptions to this pattern where more anterior sites along the septum may be the successful target site, as seen in both our own series and reports from other centers …”
