Summary

Definition:
Accessory pathways are inherited anomalous atrioventricular connections that predispose to supraventricular tachyarrhythmias.

Key features:
There are 2 main forms of accessory pathways –atrioventricular (98 %) and atriofascicular (2 %). Clinical manifestation occurs usually in infancy or in pubescent period in the form of supraventricular tachycardia and/or atrial fibrillation (30 %). Approximately 50 % of patients may be asymptomatic. Rarely there is association with sudden death due to ventricular fibrillation triggered by atrial fibrillation with rapid conduction to the ventricles via the accessory pathway.

Therapy:
Catheter ablation is highly effective method with a low risk and is the preferred therapy for symptomatic patients.

Key words:
preexcitation - accessory pathway - catheter ablation
