Abstract:
UNLABELLED:The verapamil-sensitive Belhassen tachycardia is a ventricular reentrant tachycardia, involving left-sided Purkinje fibers and abnormal Purkinje or myocardial tissue. Ablation is feasible, targeting a diastolic fascicular potential in the apical left ventricle. CASE REPORT:We report on a 13-year-old girl with left posterior fascicular ventricular tachycardia. Tachycardia stopped during ablation, targeting a left-sided distal fascicular potential, and afterward, there was no tachycardia inducible, but it reoccurred 2 weeks later. During a second procedure, we transected the left posterior fascicle by a line, also with early success. After a further recurrence, we ablated a longer proximal segment of the left posterior fascicle including its most proximal electrograms. After this ablation, there was no further recurrence. CONCLUSION:In refractory patients, proximal ablation of the posterior fascicle might be indicated.
