“…The authors targeted the left basal septum, and the LBBB disappeared within 10 minutes without VT recurrence. In a larger series ( S9.4.4.3.15 ), 1 (0.5%) of 198 patients had a transient AV block. This patient presented with left posterior fascicular VT, and the diastolic potential (P1) at the midseptum was targeted for ablation.…”

“…In the largest series of reentrant fascicular VTs, which included 160 patients with left posterior septal fascicular VT, 30 patients with left anterior septal fascicular VT, and 8 patients with left upper septal fascicular VT ( S9.4.4.3.15 ), the success and recurrence rates were 97% and 4%, respectively, for left posterior septal fascicular VT; 90% and 11%, respectively, for left anterior septal fascicular VT; and 100% and 2.5%, respectively, for left upper septal fascicular VT. Recurrence of papillary muscle fascicular VT after ablation was high ( S9.4.4.3.7 ), with 3 of 8 patients (38%) with posterior papillary muscle fascicular VT and 1 of 5 patients (20%) with anterior papillary muscle fascicular VT requiring a second ablation session for VT recurrences.…”

Fascicular ventricular tachycardia (fascicular VT) is the most common idiopathic VT of the left ventricle. It presents with a right bundle branch block morphology and predominantly left axis deviation.Most of the available evidence supports the origin of fascicular VT as localized reentry circuits located close to the fascicle of the left bundle branch. During VT, the antegrade limb of the reentry circuit is the abnormal tissue in the left ventricular septum that is associated with slow and decremental conduction with verapamil sensitivity while the retrograde limb is usually the posterior fascicle forming the fast conduction zone. Catheter ablation is a highly effective therapy with long-term success rates of 90% and a low incidence of complications. Most of the fascicular VTs can be ablated during tachycardia by targeting the pre-Purkinje potential or Purkinje potential sites.
