Key Teaching Points
The conventional mapping approach for atrioventricular accessory pathways (APs) requires an accurate interpretation of local electrograms. On the other hand, the open-window mapping (OWM) can visualize the AP connection as a breakout of the activation to the chamber of interest.
The OWM is based on the automatic annotation process in which unipolar signals with the highest −dV/dt are annotated at each obtained point, irrespective of the cardiac chamber. Thereby, the quality of the unipolar signals affects the accuracy of the OWM.
Since the novel multispline mapping catheter (Octaray, Biosense–Webster, Inc., Diamond Bar, CA) has several advantages in reducing the impact of the far-field potentials on unipolar signals, it may improve the accuracy of OWM for identifying the AP location.
