The presence of identical left lateral accessory pathways and dual AV nodal pathways in identical twins suggests a genetic role in their pathogenesis.
Highlights potential genetic factors in accessory pathways; hypothesis-generating for familial evaluation in AVRT.
LU, C.‐W., et al. : Paroxysmal Supraventricular Tachycardia in Identical Twins with the Same Left Lateral Accessory Pathways and Innocent Dual Atrioventricular Pathways. We report on 16‐year‐old, female identical twins who both have atrioventricular reentrant tachycardia caused by the same left lateral atrioventricular accessory pathway. The Kent pathway in twin A was a unidirectional retrograde accessory pathway. A manifest Kent pathway was demonstrated in twin B. Both pathways were successfully ablated by radiofrequency (RF) energy and without recurrence. In addition, innocent dual AV nodal pathways were shown in both patients. These findings suggest that genetic factors may play a role in the pathogenesis of the formation of accessory atrioventricular pathways and dual AV nodal pathways.
