Abstract

A 17-year-old adolescent presenting with multiple episodes of palpitations over the previous 9 months refractory to antiarrhythmic drug therapy and with manifest preexcitation on the 12-lead surface electrocardiogram (type B Wolff-Parkinson-White syndrome) was referred for radiofrequency (RF) catheter ablation. The initial echocardiographic evaluation was reported normal. The first procedure was tedious and prolonged, hampered by the occurrence of mechanical block in the antegrade conduction of the accessory pathway (loss of preexcitation) for the duration of the procedure. There was only retrograde conduction noted via a right lateral accessory pathway and inducible atrioventricular tachycardia with the participation of this concealed pathway, which was successfully ablated after the delivery of 9 radiofrequency energy applications (...excerpt)
