Abstract

Non-Wolf Parkinson White (WPW) Preexcitation Syndrome

Fayez A Bokhari

Mahaim (M) accessory pathway (AP) is an endocardia atrioventricular (AV) node-like structures that connect the atrium to the ventricle. M fibers were first described as accessory connections taking off from the fascicular system to the right ventricle called fasciculoventricular (FV) or from the AV node to the right ventricle called nodoventricular fibers (NV) or connecting the AV node to the fascicles called nodo-fascicular (NF). However, the majority, if not all, of Mahaim AP are atriofascicular connecting the atrium to the fasicular system. We describe two cases with non-WPW accessory pathways and their successful ablation along with a literature review.
