Catheter ablation in an 80-year-old male with late-onset Wolff-Parkinson-White syndrome

Wolff-Parkinson-White syndrome is a congenital condition involving abnormal conductive cardiac tissue between atria and ventricles, that provides a pathway for a re-entrant tachycardia circuit or rapid repetitive ventricular response during atrial fibrillation. Clinical onset is usually from childhood to middle age, and symptoms vary in severity from palpitations (with or without syncope) to cardiac arrest. Presentation varies depending on the patient’s age and presence of comorbidities, as arrhythmias are less tolerated in case of an associated heart disease. In individuals who do not experience symptoms, the condition may go unnoticed for years. We describe the case of an 80-year-old Caucasian male with late-onset of Wolff-Parkinson-White syndrome. He presented with a regular, hemodynamically unstable wide-complex tachycardia with left bundle branch morphology, successfully treated with medical therapy. After recurrence of tachycardia, he underwent an electrophysiological study that showed an orthodromic atrioventricular re-entrant tachycardia using a posterolateral accessory pathway and with functional left bundle branch block. Transseptal radiofrequency catheter ablation of the accessory pathway was successfully performed. After 15 months of follow-up, there was no tachycardia recurrence or findings of pre-excitation on the electrocardiogram. The treatment of both supraventricular and ventricular arrhythmias may be challenging especially in elderly patients. Catheter ablation of left accessory pathways with transseptal approach is feasible and effective in old patients with late-onset Wolff-Parkinson-White syndrome.
