Key result
Epicardial mapping and vectorcardiography in a child with type A WPW syndrome identified premature activation near the endocardium of the basal left ventricle, precluding surgical interruption.
Case Report (n=1)
Epicardial mapping and vectorcardiography identified a deep endocardial site of early activation in a child with variant type A WPW, demonstrating limitations of epicardial mapping for guiding surgical interruption in such cases.

Epicardial mapping may miss deep endocardial sites in type A WPW; leaves open need for combined endo-epicardial mapping in surgical candidates.
Neutze et al. (1973) conducted a case report in Atrial septal defect and a variant of type A Wolff-Parkinson-White (WPW) syndrome (n=1). Electrocardiographic and epicardial mapping was evaluated on Identification of early activation site. Epicardial mapping and vectorcardiography in a child with type A WPW syndrome identified premature activation near the endocardium of the basal left ventricle, precluding surgical interruption.
