Can you explain what ebstein's anomaly of the tricuspid valve means?

Congenital anomaly. Ebstein anomaly of the tricuspid valve is a congenital heart disease characterized by "downward" displacement of the tricuspid valve towards the apex of the right ventricle. Often there is an associated atrial septal defect. There are frequent arrhythmias, including wolf-parkinson-white syndrome. There is wide variation in the severity.
