Answer

APs are considered congenital phenomena that are related to a failure of insulating tissue maturation within the AV ring—even though their manifestations are often detected in later years, making them appear to be "acquired." On rare occasions, acquired WPW syndrome has occurred in patients who have undergone congenital heart surgery, which may be owing to an acquired functional epicardial AV connection. [12]
