What is the treatment for wolff-parkinson-white (wpw) syndrome called in which extra pathway tissue is burned away during a cardiac catheterization?

Ablation: The procedure is called ablation and it is performed by an electrophysiologist usually. The procedure is independent of cardiac catheterization.

Various treatments: Wpw syndrome is a fairly common finding and if there are no symptoms and no evidence for secondary related rhythm problems, it doesn't necessarily need treatment. When dangerous rhythms are seen or seen to be at risk then ablation of the bypass tract(s) causing the problem by an electrophysiologist is generally the treatment of choice.
